The accessible role of the given GtkAccessible implementation.
The accessible role cannot be changed once set.
The #WebKitAutomationBrowsingContextPresentation of #WebKitWebView. This should only be used when creating a new #WebKitWebView as a response to #WebKitAutomationSession::create-web-view signal request. If the new WebView was added to a new tab of current browsing context window %WEBKIT_AUTOMATION_BROWSING_CONTEXT_PRESENTATION_TAB should be used.
Capture state of the camera device. Whenever the user grants a media-request sent by the web
page, requesting video capture capabilities (navigator.mediaDevices.getUserMedia({video: true})) this property will be set to %WEBKIT_MEDIA_CAPTURE_STATE_ACTIVE.
The application can monitor this property and provide a visual indicator allowing to optionally deactivate or mute the capture device by setting this property respectively to %WEBKIT_MEDIA_CAPTURE_STATE_NONE or %WEBKIT_MEDIA_CAPTURE_STATE_MUTED.
If the capture state of the device is set to %WEBKIT_MEDIA_CAPTURE_STATE_NONE the web-page can still re-request the permission to the user. Permission desision caching is left to the application.
Whether the widget or any of its descendents can accept the input focus.
This property is meant to be set by widget implementations, typically in their instance init function.
Whether the widget can receive pointer events.
A list of css classes applied to this widget.
The name of this widget in the CSS tree.
This property is meant to be set by widget implementations, typically in their instance init function.
The cursor used by widget.
Capture state of the display device. Whenever the user grants a media-request sent by the web page, requesting screencasting capabilities (`navigator.mediaDevices.getDisplayMedia() this property will be set to %WEBKIT_MEDIA_CAPTURE_STATE_ACTIVE.
The application can monitor this property and provide a visual indicator allowing to optionally deactivate or mute the capture device by setting this property respectively to %WEBKIT_MEDIA_CAPTURE_STATE_NONE or %WEBKIT_MEDIA_CAPTURE_STATE_MUTED.
If the capture state of the device is set to %WEBKIT_MEDIA_CAPTURE_STATE_NONE the web-page can still re-request the permission to the user. Permission desision caching is left to the application.
Whether the pages loaded inside #WebKitWebView are editable. For more information see webkit_web_view_set_editable().
An estimate of the percent completion for the current loading operation. This value will range from 0.0 to 1.0 and, once a load completes, will remain at 1.0 until a new load starts, at which point it will be reset to 0.0. The value is an estimate based on the total number of bytes expected to be received for a document, including all its possible subresources and child documents.
The favicon currently associated to the #WebKitWebView. See webkit_web_view_get_favicon() for more details.
Whether the widget should grab focus when it is clicked with the mouse.
This property is only relevant for widgets that can take focus.
Whether this widget itself will accept the input focus.
How to distribute horizontal space if widget gets extra space.
Whether the widget is the default widget.
Whether the widget has the input focus.
Enables or disables the emission of the ::query-tooltip signal on widget.
A value of %TRUE indicates that widget can have a tooltip, in this case
the widget will be queried using [signalGtk.Widget::query-tooltip] to
determine whether it will provide a tooltip or not.
Override for height request of the widget.
If this is -1, the natural request will be used.
Whether to expand horizontally.
Whether to use the hexpand property.
Whether the #WebKitWebView is controlled by automation. This should only be used when creating a new #WebKitWebView as a response to #WebKitAutomationSession::create-web-view signal request.
Whether the #WebKitWebView is ephemeral. An ephemeral web view never writes website data to the client storage, no matter what #WebKitWebsiteDataManager its context is using. This is normally used to implement private browsing mode. This is a %G_PARAM_CONSTRUCT_ONLY property, so you have to create an ephemeral #WebKitWebView and it can't be changed. The ephemeral #WebKitWebsiteDataManager created for the #WebKitWebView will inherit the network settings from the #WebKitWebContext's #WebKitWebsiteDataManager. To use different settings you can get the #WebKitWebsiteDataManager with webkit_web_view_get_website_data_manager() and set the new ones. Note that all #WebKitWebViews created with an ephemeral #WebKitWebContext will be ephemeral automatically. See also webkit_web_context_new_ephemeral().
Whether the #WebKitWebView is currently loading a page. This property becomes %TRUE as soon as a new load operation is requested and before the #WebKitWebView::load-changed signal is emitted with %WEBKIT_LOAD_STARTED and at that point the active URI is the requested one. When the load operation finishes the property is set to %FALSE before #WebKitWebView::load-changed is emitted with %WEBKIT_LOAD_FINISHED.
Whether the #WebKitWebView audio is muted. When %TRUE, audio is silenced. It may still be playing, i.e. #WebKitWebView:is-playing-audio may be %TRUE.
Whether the #WebKitWebView is currently playing audio from a page. This property becomes %TRUE as soon as web content starts playing any kind of audio. When a page is no longer playing any kind of sound, the property is set back to %FALSE.
Whether the web process currently associated to the #WebKitWebView is responsive.
The GtkLayoutManager instance to use to compute the preferred size
of the widget, and allocate its children.
This property is meant to be set by widget implementations, typically in their instance init function.
Margin on bottom side of widget.
This property adds margin outside of the widget's normal size
request, the margin will be added in addition to the size from
[methodGtk.Widget.set_size_request] for example.
Margin on end of widget, horizontally.
This property supports left-to-right and right-to-left text directions.
This property adds margin outside of the widget's normal size
request, the margin will be added in addition to the size from
[methodGtk.Widget.set_size_request] for example.
Margin on start of widget, horizontally.
This property supports left-to-right and right-to-left text directions.
This property adds margin outside of the widget's normal size
request, the margin will be added in addition to the size from
[methodGtk.Widget.set_size_request] for example.
Margin on top side of widget.
This property adds margin outside of the widget's normal size
request, the margin will be added in addition to the size from
[methodGtk.Widget.set_size_request] for example.
Capture state of the microphone device. Whenever the user grants a media-request sent by the web
page, requesting audio capture capabilities (navigator.mediaDevices.getUserMedia({audio: true})) this property will be set to %WEBKIT_MEDIA_CAPTURE_STATE_ACTIVE.
The application can monitor this property and provide a visual indicator allowing to optionally deactivate or mute the capture device by setting this property respectively to %WEBKIT_MEDIA_CAPTURE_STATE_NONE or %WEBKIT_MEDIA_CAPTURE_STATE_MUTED.
If the capture state of the device is set to %WEBKIT_MEDIA_CAPTURE_STATE_NONE the web-page can still re-request the permission to the user. Permission desision caching is left to the application.
The name of the widget.
The requested opacity of the widget.
How content outside the widget's content area is treated.
This property is meant to be set by widget implementations, typically in their instance init function.
The identifier of the #WebKitWebPage corresponding to the #WebKitWebView.
The parent widget of this widget.
Whether the widget will receive the default action when it is focused.
The related #WebKitWebView used when creating the view to share the same web process. This property is not readable because the related web view is only valid during the object construction.
The GtkRoot widget of the widget tree containing this widget.
This will be %NULL if the widget is not contained in a root widget.
The scale factor of the widget.
Whether the widget responds to input.
The #WebKitSettings of the view.
The main frame document title of this #WebKitWebView. If the title has not been received yet, it will be %NULL.
Sets the text of tooltip to be the given string, which is marked up with Pango markup.
Also see [methodGtk.Tooltip.set_markup].
This is a convenience property which will take care of getting the
tooltip shown if the given string is not %NULL:
[propertyGtk.Widget:has-tooltip] will automatically be set to %TRUE
and there will be taken care of [signalGtk.Widget::query-tooltip] in
the default signal handler.
Note that if both [propertyGtk.Widget:tooltip-text] and
[propertyGtk.Widget:tooltip-markup] are set, the last one wins.
Sets the text of tooltip to be the given string.
Also see [methodGtk.Tooltip.set_text].
This is a convenience property which will take care of getting the

the default signal handler.
Note that if both [propertyGtk.Widget:tooltip-text] and
[propertyGtk.Widget:tooltip-markup] are set, the last one wins.
The current active URI of the #WebKitWebView. See webkit_web_view_get_uri() for more details.
The #WebKitUserContentManager of the view.
How to distribute vertical space if widget gets extra space.
Whether to expand vertically.
Whether to use the vexpand property.
Whether the widget is visible.
The #WebKitWebContext of the view.
The #WebKitWebsitePolicies for the view.
Override for width request of the widget.
If this is -1, the natural request will be used.
The zoom level of the #WebKitWebView content. See webkit_web_view_set_zoom_level() for more details.
Enable or disable an action installed with gtk_widget_class_install_action().
action name, such as "clipboard.paste"
whether the action is now enabled
For widgets that can be “activated” (buttons, menu items, etc.), this function activates them.
The activation will emit the signal set using
[methodGtk.WidgetClass.set_activate_signal] during class initialization.
Activation is what happens when you press Enter on a widget during key navigation.
If you wish to handle the activation keybinding yourself, it is
recommended to use [methodGtk.WidgetClass.add_shortcut] with an action
created with [ctorGtk.SignalAction.new].
If widget isn't activatable, the function returns %FALSE.
Looks up the action in the action groups associated with
widget and its ancestors, and activates it.
If the action is in an action group added with
[methodGtk.Widget.insert_action_group], the name is expected
to be prefixed with the prefix that was used when the group was
inserted.
The arguments must match the actions expected parameter type,
as returned by g_action_get_parameter_type().
Activates the default.activate action from widget.
Adds controller to widget so that it will receive events.
You will usually want to call this function right after
creating any kind of [classGtk.EventController].
a GtkEventController that hasn't been added to a widget yet
Adds a style class to widget.
After calling this function, the widgets style will match
for css_class, according to CSS matching rules.
Use [methodGtk.Widget.remove_css_class] to remove the
style again.
The style class to add to widget, without the leading '.' used for notation of style classes
Adds a widget to the list of mnemonic labels for this widget.
See [methodGtk.Widget.list_mnemonic_labels]. Note the
list of mnemonic labels for the widget is cleared when the
widget is destroyed, so the caller must make sure to update
its internal state at this point as well.
Queues an animation frame update and adds a callback to be called before each frame.
Until the tick callback is removed, it will be called frequently
(usually at the frame rate of the output device or as quickly as
the application can be repainted, whichever is slower). For this
reason, is most suitable for handling graphics that change every
frame or every few frames. The tick callback does not automatically
imply a relayout or repaint. If you want a repaint or relayout, and
aren’t changing widget properties that would trigger that (for example,
changing the text of a GtkLabel), then you will have to call
[methodGtk.Widget.queue_resize] or [methodGtk.Widget.queue_draw]
yourself.
[methodGdk.FrameClock.get_frame_time] should generally be used
for timing continuous animations and
[methodGdk.FrameTimings.get_predicted_presentation_time] if you are
trying to display isolated frames at particular times.
This is a more convenient alternative to connecting directly to the
[signalGdk.FrameClock::update] signal of GdkFrameClock, since you
don't have to worry about when a GdkFrameClock is assigned to a widget.
function to call for updating animations
This function is only used by GtkWidget subclasses, to
assign a size, position and (optionally) baseline to their
child widgets.
In this function, the allocation and baseline may be adjusted. The given allocation will be forced to be bigger than the widget's minimum size, as well as at least 0×0 in size.
For a version that does not take a transform, see
[methodGtk.Widget.size_allocate].
New width of widget
New height of widget
New baseline of widget, or -1
Transformation to be applied to widget
Creates a binding between source_property on source and target_property
on target.
Whenever the source_property is changed the target_property is
updated using the same value. For instance:
g_object_bind_property (action, "active", widget, "sensitive", 0);
Will result in the "sensitive" property of the widget #GObject instance to be updated with the same value of the "active" property of the action #GObject instance.
If flags contains %G_BINDING_BIDIRECTIONAL then the binding will be mutual:
if target_property on target changes then the source_property on source
will be updated as well.
The binding will automatically be removed when either the source or the
target instances are finalized. To remove the binding without affecting the
source and the target you can just call g_object_unref() on the returned
#GBinding instance.
Removing the binding by calling g_object_unref() on it must only be done if
the binding, source and target are only used from a single thread and it
is clear that both source and target outlive the binding. Especially it
is not safe to rely on this if the binding, source or target can be
finalized from different threads. Keep another reference to the binding and
use g_binding_unbind() instead to be on the safe side.
A #GObject can have multiple bindings.

Creates a binding between source_property on source and target_property
on target, allowing you to set the transformation functions to be used by
the binding.

Determines whether web_view has a previous history item.
Determines whether web_view has a next history item.

Called by widgets as the user moves around the window using keyboard shortcuts.
The direction argument indicates what kind of motion is taking place (up,
down, left, right, tab forward, tab backward).
This function calls the [vfuncGtk.Widget.focus] virtual function; widgets
can override the virtual function in order to implement appropriate focus
behavior.
The default focus() virtual function for a widget should return TRUE if
moving in direction left the focus on a focusable location inside that
widget, and FALSE if moving in direction moved the focus outside the
widget. When returning TRUE, widgets normallycall [methodGtk.Widget.grab_focus]
to place the focus accordingly; when returning FALSE, they don’t modify
the current focus location.
This function is used by custom widget implementations; if you're
writing an app, you’d use [methodGtk.Widget.grab_focus] to move
the focus to a particular widget.
direction of focus movement
Computes the bounds for widget in the coordinate space of target.
FIXME: Explain what "bounds" are.
If the operation is successful, %TRUE is returned. If widget has no
bounds or the bounds cannot be expressed in target's coordinate space
(for example if both widgets are in different windows), %FALSE is
returned and bounds is set to the zero rectangle.
It is valid for widget and target to be the same widget.
Computes whether a container should give this widget extra space when possible.
Containers should check this, rather than looking at
[methodGtk.Widget.get_hexpand] or [methodGtk.Widget.get_vexpand].
This function already checks whether the widget is visible, so visibility does not need to be checked separately. Non-visible widgets are not expanded.
The computed expand value uses either the expand setting explicitly set on the widget itself, or, if none has been explicitly set, the widget may expand if some of its children do.
expand direction
Translates the given point in widget's coordinates to coordinates
relative to target’s coordinate system.
In order to perform this operation, both widgets must share a common ancestor.
the GtkWidget to transform into
a point in widget's coordinate system
Computes a matrix suitable to describe a transformation from
widget's coordinate system into target's coordinate system.
The transform can not be computed in certain cases, for example
when widget and target do not share a common ancestor. In that
case out_transform gets set to the identity matrix.
Tests if the point at (x, y) is contained in widget.
The coordinates for (x, y) must be in widget coordinates, so
(0, 0) is assumed to be the top left of widget's content area.
X coordinate to test, relative to widget's origin
Y coordinate to test, relative to widget's origin
Creates a new PangoLayout with the appropriate font map,
font description, and base direction for drawing text for
this widget.
If you keep a PangoLayout created in this way around,
you need to re-create it when the widget PangoContext
is replaced. This can be tracked by listening to changes
of the [propertyGtk.Widget:root] property on the widget.

Notifies the user about an input-related error on this widget.
If the [propertyGtk.Settings:gtk-error-bell] setting is %TRUE,
it calls [methodGdk.Surface.beep], otherwise it does nothing.
Note that the effect of [methodGdk.Surface.beep] can be configured
in many ways, depending on the windowing backend and the desktop
environment or window manager that is used.

webkit_web_view_can_execute_editing_command() to check whether
it's possible to execute the command.

This function is intended for #GObject implementations to re-enforce a [floating][floating-ref] object reference. Doing this is seldom required: all #GInitiallyUnowneds are created with a floating reference which usually just needs to be sunken by calling g_object_ref_sink().
Increases the freeze count on object. If the freeze count is
non-zero, the emission of "notify" signals on object is
stopped. The signals are queued until the freeze count is decreased
to zero. Duplicate notifications are squashed so that at most one
#GObject::notify signal is emitted for each property modified while the
object is frozen.
This is necessary for accessors that modify multiple properties to prevent premature notification while the object is still being modified.
Retrieves the GtkAccessibleRole for the given GtkAccessible.
Returns the baseline that has currently been allocated to widget.
This function is intended to be used when implementing handlers
for the GtkWidgetClass.snapshot() function, and when allocating
child widgets in GtkWidgetClass.size_allocate().
Returns the height that has currently been allocated to widget.
Returns the width that has currently been allocated to widget.
Retrieves the widget’s allocation.
Note, when implementing a layout container: a widget’s allocation
will be its “adjusted” allocation, that is, the widget’s parent
typically calls [methodGtk.Widget.size_allocate] with an allocation,
and that allocation is then adjusted (to handle margin
and alignment for example) before assignment to the widget.
[methodGtk.Widget.get_allocation] returns the adjusted allocation that
was actually assigned to the widget. The adjusted allocation is
guaranteed to be completely contained within the
[methodGtk.Widget.size_allocate] allocation, however.
So a layout container is guaranteed that its children stay inside the assigned bounds, but not that they have exactly the bounds the container assigned.
Gets the first ancestor of widget with type widget_type.
For example, gtk_widget_get_ancestor (widget, GTK_TYPE_BOX)
gets the first GtkBox that’s an ancestor of widget. No
reference will be added to the returned widget; it should
not be unreferenced.
Note that unlike [methodGtk.Widget.is_ancestor], this function
considers widget to be an ancestor of itself.

Get the presentation type of #WebKitWebView when created for automation.
Obtains the #WebKitBackForwardList associated with the given #WebKitWebView. The #WebKitBackForwardList is owned by the #WebKitWebView.
Gets the ID of the buildable object.
GtkBuilder sets the name based on the ID attribute
of the
Get the camera capture state of a #WebKitWebView.
Determines whether the input focus can enter widget or any
of its children.
See [methodGtk.Widget.set_focusable].
Queries whether widget can be the target of pointer events.
Gets the value set with gtk_widget_set_child_visible().
If you feel a need to use this function, your code probably needs reorganization.
This function is only useful for container implementations and should never be called by an application.
Gets the web context of web_view.
Returns the list of style classes applied to widget.
Returns the CSS name that is used for self.
Returns the current custom character encoding name of web_view.
Gets a named field from the objects table of associations (see g_object_set_data()).
name of the key for that association
Gets the reading direction for a particular widget.
See [methodGtk.Widget.set_direction].
Get the GdkDisplay for the toplevel window associated with
this widget.
This function can only be called after the widget has been
added to a widget hierarchy with a GtkWindow at the top.
In general, you should only create display specific resources when a widget has been realized, and you should free those resources when the widget is unrealized.
Get the display capture state of a #WebKitWebView.
Gets the web editor state of web_view.
Gets the value of the #WebKitWebView:estimated-load-progress property.
You can monitor the estimated progress of a load operation by
connecting to the notify::estimated-load-progress signal of web_view.
Gets the #WebKitFindController that will allow the caller to query the #WebKitWebView for the text to look for.
Returns whether the widget should grab focus when it is clicked with the mouse.
See [methodGtk.Widget.set_focus_on_click].
Determines whether widget can own the input focus.
See [methodGtk.Widget.set_focusable].
Returns the cairo_font_options_t of widget.
Seee [methodGtk.Widget.set_font_options].
Obtains the frame clock for a widget.
The frame clock is a global “ticker” that can be used to drive
animations and repaints. The most common reason to get the frame
clock is to call [methodGdk.FrameClock.get_frame_time], in order
to get a time to use for animating. For example you might record
the start of the animation with an initial value from
[methodGdk.FrameClock.get_frame_time], and then update the animation
by calling [methodGdk.FrameClock.get_frame_time] again during each repaint.
[methodGdk.FrameClock.request_phase] will result in a new frame on the
clock, but won’t necessarily repaint any widgets. To repaint a
widget, you have to use [methodGtk.Widget.queue_draw] which invalidates
the widget (thus scheduling it to receive a draw on the next
frame). gtk_widget_queue_draw() will also end up requesting a frame
on the appropriate frame clock.
A widget’s frame clock will not change while the widget is mapped. Reparenting a widget (which implies a temporary unmap) can change the widget’s frame clock.
Unrealized widgets do not have a frame clock.
Returns the current value of the has-tooltip property.
Returns the content height of the widget.
This function returns the height passed to its
size-allocate implementation, which is the height you
should be using in [vfuncGtk.Widget.snapshot].
For pointer events, see [methodGtk.Widget.contains].
Gets whether the widget would like any available extra horizontal space.
When a user resizes a GtkWindow, widgets with expand=TRUE
generally receive the extra space. For example, a list or
scrollable area or document in your window would often be set to
expand.
Containers should use [methodGtk.Widget.compute_expand] rather
than this function, to see whether a widget, or any of its children,
has the expand flag set. If any child of a widget wants to
expand, the parent may ask to expand also.
This function only looks at the widget’s own hexpand flag, rather than computing whether the entire widget tree rooted at this widget wants to expand.
Gets whether gtk_widget_set_hexpand() has been used to explicitly set the expand flag on this widget.
If [propertyGtk.Widget:hexpand] property is set, then it
overrides any computed expand value based on child widgets.
If hexpand is not set, then the expand value depends on
whether any children of the widget would like to expand.
There are few reasons to use this function, but it’s here for completeness and consistency.
Get the #WebKitInputMethodContext currently in use by web_view, or %NULL if no input method is being used.
Get the #WebKitWebInspector associated to web_view
Gets the mute state of web_view.
Retrieves the layout manager used by widget.
See [methodGtk.Widget.set_layout_manager].
Return the main resource of web_view.
Whether the widget is mapped.
Gets the bottom margin of widget.
Gets the end margin of widget.
Gets the start margin of widget.
Gets the top margin of widget.
Get the microphone capture state of a #WebKitWebView.
Retrieves the name of a widget.
See [methodGtk.Widget.set_name] for the significance of widget names.
#Fetches the requested opacity for this widget.
See [methodGtk.Widget.set_opacity].
Returns the widgets overflow value.
Get the identifier of the #WebKitWebPage corresponding to the #WebKitWebView
Gets a PangoContext with the appropriate font map, font description,
and base direction for this widget.
Unlike the context returned by [methodGtk.Widget.create_pango_context],
this context is owned by the widget (it can be used until the screen
for the widget changes or the widget is removed from its toplevel),
and will be updated to match any changes to the widget’s attributes.
This can be tracked by listening to changes of the
[propertyGtk.Widget:root] property on the widget.
Retrieves the minimum and natural size of a widget, taking into account the widget’s preference for height-for-width management.
This is used to retrieve a suitable size by container widgets which do
not impose any restrictions on the child placement. It can be used
to deduce toplevel window and menu sizes as well as child widgets in
free-form containers such as GtkFixed.
Handle with care. Note that the natural height of a height-for-width widget will generally be a smaller size than the minimum height, since the required height for the natural width is generally smaller than the required height for the minimum width.
Use [idgtk_widget_measure] if you want to support baseline alignment.
Gets a property of an object.
The value can be:
In general, a copy is made of the property contents and the caller is responsible for freeing the memory by calling g_value_unset().
Note that g_object_get_property() is really intended for language bindings, g_object_get() is much more convenient for C programming.
the name of the property to get
return location for the property value
This function gets back user data pointers stored via g_object_set_qdata().
A #GQuark, naming the user data pointer
Determines whether widget is realized.
Determines whether widget is always treated as the default widget
within its toplevel when it has the focus, even if another widget
is the default.
See [methodGtk.Widget.set_receives_default].
Gets whether the widget prefers a height-for-width layout or a width-for-height layout.
Single-child widgets generally propagate the preference of their child, more complex widgets need to request something either in context of their children or in context of their allocation capabilities.
Retrieves the internal scale factor that maps from window coordinates to the actual device pixels.
On traditional systems this is 1, on high density outputs, it can be a higher value (typically 2).
See [methodGdk.Surface.get_scale_factor].
Returns the widget’s sensitivity.
This function returns the value that has been set using
[methodGtk.Widget.set_sensitive]).
The effective sensitivity of a widget is however determined
by both its own and its parent widget’s sensitivity.
See [methodGtk.Widget.is_sensitive].
Gets the current session state of web_view
Gets the #WebKitSettings currently applied to web_view.
If no other #WebKitSettings have been explicitly applied to
web_view with webkit_web_view_set_settings(), the default
#WebKitSettings will be returned. This method always returns
a valid #WebKitSettings object.
To modify any of the web_view settings, you can either create
a new #WebKitSettings object with webkit_settings_new(), setting
the desired preferences, and then replace the existing web_view
settings with webkit_web_view_set_settings() or get the existing
web_view settings and update it directly. #WebKitSettings objects
can be shared by multiple #WebKitWebViews, so modifying
the settings of a #WebKitWebView would affect other
#WebKitWebViews using the same #WebKitSettings.
Gets the settings object holding the settings used for this widget.
Note that this function can only be called when the GtkWidget
is attached to a toplevel, since the settings object is specific
to a particular GdkDisplay. If you want to monitor the widget for
changes in its settings, connect to the notify::display signal.
Returns the content width or height of the widget.
Which dimension is returned depends on orientation.
This is equivalent to calling [methodGtk.Widget.get_width]
for %GTK_ORIENTATION_HORIZONTAL or [methodGtk.Widget.get_height]
for %GTK_ORIENTATION_VERTICAL, but can be used when
writing orientation-independent code, such as when
implementing [ifaceGtk.Orientable] widgets.
the orientation to query
Gets the size request that was explicitly set for the widget using gtk_widget_set_size_request().
A value of -1 stored in width or height indicates that that
dimension has not been set explicitly and the natural requisition
of the widget will be used instead. See
[methodGtk.Widget.set_size_request]. To get the size a widget will
actually request, call [methodGtk.Widget.measure] instead of
this function.
Asynchronously retrieves a snapshot of web_view for region.

Returns the widget state as a flag set.
It is worth mentioning that the effective %GTK_STATE_FLAG_INSENSITIVE
state will be returned, that is, also based on parent insensitivity,
even if widget itself is sensitive.
Also note that if you are looking for a way to obtain the
[flagsGtk.StateFlags] to pass to a [classGtk.StyleContext]
method, you should look at [methodGtk.StyleContext.get_state].
Returns the style context associated to widget.
The returned object is guaranteed to be the same
for the lifetime of widget.
Fetch an object build from the template XML for widget_type in
this widget instance.
This will only report children which were previously declared
with [methodGtk.WidgetClass.bind_template_child_full] or one of its
variants.
This function is only meant to be called for code which is private
to the widget_type which declared the child and is meant for language
bindings which cannot easily make use of the GObject structure offsets.
The GType to get a template child for
The “id” of the child defined in the template XML
Gets the value of the #WebKitWebView:title property.
You can connect to notify::title signal of web_view to
be notified when the title has been received.
Retrieves the #GTlsCertificate associated with the main resource of web_view,
and the #GTlsCertificateFlags showing what problems, if any, have been found
with that certificate.
If the connection is not HTTPS, this function returns %FALSE.
This function should be called after a response has been received from the
server, so you can connect to #WebKitWebView::load-changed and call this function
when it's emitted with %WEBKIT_LOAD_COMMITTED event.
Note that this function provides no information about the security of the web page if the current #WebKitTLSErrorsPolicy is %WEBKIT_TLS_ERRORS_POLICY_IGNORE, as subresources of the page may be controlled by an attacker. This function may safely be used to determine the security status of the current page only if the current #WebKitTLSErrorsPolicy is %WEBKIT_TLS_ERRORS_POLICY_FAIL, in which case subresources that fail certificate verification will be blocked.
Gets the contents of the tooltip for widget.
If the tooltip has not been set using
[methodGtk.Widget.set_tooltip_markup], this
function returns %NULL.
Gets the contents of the tooltip for widget.
If the widget's tooltip was set using
[methodGtk.Widget.set_tooltip_markup],
this function will return the escaped text.
Returns the current active URI of web_view. The active URI might change during
a load operation:
You can monitor the active URI by connecting to the notify::uri
signal of web_view.
Gets the user content manager associated to web_view.
Gets whether the widget would like any available extra vertical space.
See [methodGtk.Widget.get_hexpand] for more detail.
Gets whether gtk_widget_set_vexpand() has been used to explicitly set the expand flag on this widget.
See [methodGtk.Widget.get_hexpand_set] for more detail.
Determines whether the widget is visible.
If you want to take into account whether the widget’s
parent is also marked as visible, use
[methodGtk.Widget.is_visible] instead.
This function does not check if the widget is obscured in any way.
See [methodGtk.Widget.set_visible].
Get the #WebKitWebsiteDataManager associated to web_view. If web_view is not ephemeral,
the returned #WebKitWebsiteDataManager will be the same as the #WebKitWebsiteDataManager
of web_view's #WebKitWebContext.
Gets the default website policies set on construction in the
web_view. These can be overridden on a per-origin basis via the
#WebKitWebView::decide-policy signal handler.
See also webkit_policy_decision_use_with_policies().
Returns the content width of the widget.
This function returns the width passed to its
size-allocate implementation, which is the width you
should be using in [vfuncGtk.Widget.snapshot].
For pointer events, see [methodGtk.Widget.contains].
Get the #WebKitWindowProperties object containing the properties
that the window containing web_view should have.
Get the zoom level of web_view, i.e. the factor by which the
view contents are scaled with respect to their original size.
Gets n_properties properties for an object.
Obtained properties will be set to values. All properties must be valid.
Warnings will be emitted and undefined behaviour may result if invalid
properties are passed in.

Loads the previous history item. You can monitor the load operation by connecting to #WebKitWebView::load-changed signal.
Loads the next history item. You can monitor the load operation by connecting to #WebKitWebView::load-changed signal.
Loads the specific history item list_item.
You can monitor the load operation by connecting to
#WebKitWebView::load-changed signal.
a #WebKitBackForwardListItem
Causes widget to have the keyboard focus for the GtkWindow it's inside.
If widget is not focusable, or its [vfuncGtk.Widget.grab_focus]
implementation cannot transfer the focus to a descendant of widget
that is focusable, it will not take focus and %FALSE will be returned.
Calling [methodGtk.Widget.grab_focus] on an already focused widget
is allowed, should not have an effect, and return %TRUE.
Returns whether css_class is currently applied to widget.
A style class, without the leading '.' used for notation of style classes
Determines if the widget should show a visible indication that it has the global input focus.
This is a convenience function that takes into account whether
focus indication should currently be shown in the toplevel window
of widget. See [methodGtk.Window.get_focus_visible] for more
information about focus indication.
To find out if the widget has the global input focus, use
[methodGtk.Widget.has_focus].
Reverses the effects of gtk_widget_show().
This is causing the widget to be hidden (invisible to the user).
Returns whether the widget is currently being destroyed.
This information can sometimes be used to avoid doing unnecessary work.
Creates and initializes child widgets defined in templates.
This function must be called in the instance initializer
for any class which assigned itself a template using
[methodGtk.WidgetClass.set_template].
It is important to call this function in the instance initializer
of a GtkWidget subclass and not in GObject.constructed() or
GObject.constructor() for two reasons:
g_object_new() on a widget with composite templates,
it’s important to build the composite widgets before the construct
properties are set. Properties passed to g_object_new() should
take precedence over properties set in the private template XMLA good rule of thumb is to call this function as the first thing in an instance initialization function.
Inserts group into widget.
Children of widget that implement [ifaceGtk.Actionable] can
then be associated with actions in group by setting their
“action-name” to prefix.action-name.
Note that inheritance is defined for individual actions. I.e.
even if you insert a group with prefix prefix, actions with
the same prefix will still be inherited from the parent, unless
the group contains an action with the same name.
If group is %NULL, a previously inserted group for name is
removed from widget.
the prefix for actions in group
a GActionGroup, or %NULL to remove the previously inserted group for name
Inserts widget into the child widget list of parent.
It will be placed after previous_sibling, or at the beginning if
previous_sibling is %NULL.
After calling this function, gtk_widget_get_prev_sibling(widget)
will return previous_sibling.
If parent is already set as the parent widget of widget, this
function can also be used to reorder widget in the child widget
list of parent.
This API is primarily meant for widget implementations; if you are just using a widget, you must use its own API for adding children.
the parent GtkWidget to insert widget into
the new previous sibling of widget
Inserts widget into the child widget list of parent.
It will be placed before next_sibling, or at the end if
next_sibling is %NULL.
After calling this function, gtk_widget_get_next_sibling(widget)
will return next_sibling.
If parent is already set as the parent widget of widget, this function
can also be used to reorder widget in the child widget list of parent.
This API is primarily meant for widget implementations; if you are just using a widget, you must use its own API for adding children.
the parent GtkWidget to insert widget into
the new next sibling of widget
Determines whether widget can be drawn to.
A widget can be drawn if it is mapped and visible.
Checks whether object has a [floating][floating-ref] reference.
Determines if the widget is the focus widget within its toplevel.
This does not mean that the [propertyGtk.Widget:has-focus]
property is necessarily set; [propertyGtk.Widget:has-focus]
will only be set if the toplevel widget additionally has the
global input focus.
Returns the widget’s effective sensitivity.
This means it is sensitive itself and also its parent widget is sensitive.
Determines whether the widget and all its parents are marked as visible.
This function does not check if the widget is obscured in any way.
See also [methodGtk.Widget.get_visible] and
[methodGtk.Widget.set_visible].
Emits the ::keynav-failed signal on the widget.
This function should be called whenever keyboard navigation within a single widget hits a boundary.
The return value of this function should be interpreted
in a way similar to the return value of
[methodGtk.Widget.child_focus]. When %TRUE is returned,
stay in the widget, the failed keyboard navigation is OK
and/or there is nowhere we can/should move the focus to.
When %FALSE is returned, the caller should continue with
keyboard navigation outside the widget, e.g. by calling
[methodGtk.Widget.child_focus] on the widget’s toplevel.
The default [signalGtk.Widget::keynav-failed] handler returns
%FALSE for %GTK_DIR_TAB_FORWARD and %GTK_DIR_TAB_BACKWARD.
For the other values of GtkDirectionType it returns %TRUE.
Whenever the default handler returns %TRUE, it also calls
[methodGtk.Widget.error_bell] to notify the user of the
failed keyboard navigation.
A use case for providing an own implementation of ::keynav-failed
(either by connecting to it or by overriding it) would be a row of
[classGtk.Entry] widgets where the user should be able to navigate
the entire row with the cursor keys, as e.g. known from user
interfaces that require entering license keys.
direction of focus movement
Returns the widgets for which this widget is the target of a mnemonic.
Typically, these widgets will be labels. See, for example,
[methodGtk.Label.set_mnemonic_widget].
The widgets in the list are not individually referenced.
If you want to iterate through the list and perform actions
involving callbacks that might destroy the widgets, you
must call g_list_foreach (result, (GFunc)g_object_ref, NULL)
first, and then unref all the widgets afterwards.
Load the given content string for the URI content_uri.
This allows clients to display page-loading errors in the #WebKitWebView itself.
When this method is called from #WebKitWebView::load-failed signal to show an
error page, then the back-forward list is maintained appropriately.
For everything else this method works the same way as webkit_web_view_load_html().
the new content to display as the main page of the web_view
the URI for the alternate page content
the base URI for relative locations or %NULL
Load the specified bytes into web_view using the given mime_type and encoding.
When mime_type is %NULL, it defaults to "text/html".
When encoding is %NULL, it defaults to "UTF-8".
When base_uri is %NULL, it defaults to "about:blank".
You can monitor the load operation by connecting to #WebKitWebView::load-changed signal.
input data to load
the MIME type of bytes, or %NULL
the character encoding of bytes, or %NULL
the base URI for relative locations or %NULL
Load the given content string with the specified base_uri.
If base_uri is not %NULL, relative URLs in the content will be
resolved against base_uri and absolute local paths must be children of the base_uri.
For security reasons absolute local paths that are not children of base_uri
will cause the web process to terminate.
If you need to include URLs in content that are local paths in a different
directory than base_uri you can build a data URI for them. When base_uri is %NULL,
it defaults to "about:blank". The mime type of the document will be "text/html".
You can monitor the load operation by connecting to #WebKitWebView::load-changed signal.
The HTML string to load
The base URI for relative locations or %NULL
Load the specified plain_text string into web_view. The mime type of
document will be "text/plain". You can monitor the load
operation by connecting to #WebKitWebView::load-changed signal.
The plain text to load
Requests loading of the specified #WebKitURIRequest. You can monitor the load operation by connecting to #WebKitWebView::load-changed signal.
a #WebKitURIRequest to load
Requests loading of the specified URI string. You can monitor the load operation by connecting to #WebKitWebView::load-changed signal.
an URI string
Causes a widget to be mapped if it isn’t already.
This function is only for use in widget implementations.
Measures widget in the orientation orientation and for the given for_size.
As an example, if orientation is %GTK_ORIENTATION_HORIZONTAL and for_size
is 300, this functions will compute the minimum and natural width of widget
if it is allocated at a height of 300 pixels.
See GtkWidget’s geometry management section for
a more details on implementing GtkWidgetClass.measure().
the orientation to measure
Size for the opposite of orientation, i.e. if orientation is %GTK_ORIENTATION_HORIZONTAL, this is the height the widget should be measured with. The %GTK_ORIENTATION_VERTICAL case is analogous. This way, both height-for-width and width-for-height requests can be implemented. If no size is known, -1 can be passed.
Emits the ::mnemonic-activate signal.
See [signalGtk.Widget::mnemonic-activate].
%TRUE if there are other widgets with the same mnemonic
Emits a "notify" signal for the property property_name on object.
When possible, eg. when signaling a property change from within the class that registered the property, you should use g_object_notify_by_pspec() instead.
Note that emission of the notify signal may be blocked with g_object_freeze_notify(). In this case, the signal emissions are queued and will be emitted (in reverse order) when g_object_thaw_notify() is called.
the name of a property installed on the class of object.
Emits a "notify" signal for the property specified by pspec on object.
This function omits the property name lookup, hence it is faster than g_object_notify().
One way to avoid using g_object_notify() from within the class that registered the properties, and using g_object_notify_by_pspec() instead, is to store the GParamSpec used with g_object_class_install_property() inside a static array, e.g.:
enum
{
PROP_0,
PROP_FOO,
PROP_LAST
};
static GParamSpec *properties[PROP_LAST];
static void
my_object_class_init (MyObjectClass *klass)
{
properties[PROP_FOO] = g_param_spec_int ("foo", "Foo", "The foo",
0, 100,
50,
G_PARAM_READWRITE);
g_object_class_install_property (gobject_class,
PROP_FOO,
properties[PROP_FOO]);
}
and then notify a change on the "foo" property with:
g_object_notify_by_pspec (self, properties[PROP_FOO]);
the #GParamSpec of a property installed on the class of object.
Returns a GListModel to track the children of widget.
Calling this function will enable extra internal bookkeeping to track children and emit signals on the returned listmodel. It may slow down operations a lot.
Applications should try hard to avoid calling this function because of the slowdowns.
Returns a GListModel to track the [classGtk.EventController]s
of widget.
Calling this function will enable extra internal bookkeeping to track controllers and emit signals on the returned listmodel. It may slow down operations a lot.
Applications should try hard to avoid calling this function because of the slowdowns.
Finds the descendant of widget closest to the point (x, y).
The point must be given in widget coordinates, so (0, 0) is assumed
to be the top left of widget's content area.
Usually widgets will return %NULL if the given coordinate is not
contained in widget checked via [methodGtk.Widget.contains].
Otherwise they will recursively try to find a child that does
not return %NULL. Widgets are however free to customize their
picking algorithm.
This function is used on the toplevel to determine the widget below the mouse cursor for purposes of hover highlighting and delivering events.
X coordinate to test, relative to widget's origin
Y coordinate to test, relative to widget's origin
Flags to influence what is picked
Flags the widget for a rerun of the [vfuncGtk.Widget.size_allocate]
function.
Use this function instead of [methodGtk.Widget.queue_resize]
when the widget's size request didn't change but it wants to
reposition its contents.
An example user of this function is [methodGtk.Widget.set_halign].
This function is only for use in widget implementations.
Schedules this widget to be redrawn in the paint phase of the current or the next frame.
This means widget's [vfuncGtk.Widget.snapshot]
implementation will be called.
Flags a widget to have its size renegotiated.
This should be called when a widget for some reason has a new
size request. For example, when you change the text in a
[classGtk.Label], the label queues a resize to ensure there’s
enough space for the new text.
Note that you cannot call gtk_widget_queue_resize() on a widget
from inside its implementation of the [vfuncGtk.Widget.size_allocate]
virtual method. Calls to gtk_widget_queue_resize() from inside
[vfuncGtk.Widget.size_allocate] will be silently ignored.
This function is only for use in widget implementations.
Creates the GDK resources associated with a widget.
Normally realization happens implicitly; if you show a widget and all its parent containers, then the widget will be realized and mapped automatically.
Realizing a widget requires all the widget’s parent widgets to be
realized; calling this function realizes the widget’s parents
in addition to widget itself. If a widget is not yet inside a
toplevel window when you realize it, bad things will happen.
This function is primarily used in widget implementations, and
isn’t very useful otherwise. Many times when you think you might
need it, a better approach is to connect to a signal that will be
called after the widget is realized automatically, such as
[signalGtk.Widget::realize].
Increase the reference count of object, and possibly remove the
[floating][floating-ref] reference, if object has a floating reference.
In other words, if the object is floating, then this call "assumes ownership" of the floating reference, converting it to a normal reference by clearing the floating flag while leaving the reference count unchanged. If the object is not floating, then this call adds a new normal reference increasing the reference count by one.
Since GLib 2.56, the type of object will be propagated to the return type
under the same conditions as for g_object_ref().
Reloads the current contents of web_view.
See also webkit_web_view_reload_bypass_cache().
Reloads the current contents of web_view without
using any cached data.
Removes controller from widget, so that it doesn't process
events anymore.
It should not be used again.
Widgets will remove all event controllers automatically when they are destroyed, there is normally no need to call this function.
a GtkEventController
Removes a style from widget.
After this, the style of widget will stop matching for css_class.
The style class to remove from widget, without the leading '.' used for notation of style classes
Removes a widget from the list of mnemonic labels for this widget.
See [methodGtk.Widget.list_mnemonic_labels]. The widget must
have previously been added to the list with
[methodGtk.Widget.add_mnemonic_label].
a GtkWidget that was previously set as a mnemonic label for widget with [methodGtk.Widget.add_mnemonic_label]
Removes a tick callback previously registered with gtk_widget_add_tick_callback().
an id returned by [methodGtk.Widget.add_tick_callback]
Resets the accessible property to its default value.
a GtkAccessibleProperty
Resets the accessible relation to its default value.
a GtkAccessibleRelation
Resets the accessible state to its default value.
a GtkAccessibleState
Restore the web_view session state from state
a #WebKitWebViewSessionState
Releases all references to other objects. This can be used to break reference cycles.
This function should only be called from object system implementations.
Asynchronously run script in the context of the current page in web_view. If
WebKitSettings:enable-javascript is FALSE, this method will do nothing.
When the operation is finished, callback will be called. You can then call
webkit_web_view_run_javascript_finish() to get the result of the operation.

if (!js_result) {
g_warning ("Error running javascript: %s", error->message);

Sets the color that will be used to draw the web_view background before
the actual contents are rendered. Note that if the web page loaded in web_view
specifies a background color, it will take precedence over the rgba color.
By default the web_view background color is opaque white.
Note that the parent window must have a RGBA visual and

Set the camera capture state of a #WebKitWebView.
If #WebKitSettings:enable-mediastream is %FALSE, this method will have no visible effect. Once the state of the device has been set to %WEBKIT_MEDIA_CAPTURE_STATE_NONE it cannot be changed anymore. The page can however request capture again using the mediaDevices API.
a #WebKitMediaCaptureState
Specifies whether the input focus can enter the widget or any of its children.
Applications should set can_focus to %FALSE to mark a
widget as for pointer/touch use only.
Note that having can_focus be %TRUE is only one of the
necessary conditions for being focusable. A widget must
also be sensitive and focusable and not have an ancestor
that is marked as not can-focus in order to receive input
focus.
See [methodGtk.Widget.grab_focus] for actually setting
the input focus on a widget.
whether or not the input focus can enter the widget or any of its children
Sets whether widget can be the target of pointer events.
whether this widget should be able to receive pointer events
Sets whether widget should be mapped along with its parent.
The child visibility can be set for widget before it is added
to a container with [methodGtk.Widget.set_parent], to avoid
mapping children unnecessary before immediately unmapping them.
However it will be reset to its default state of %TRUE when the
widget is removed from a container.
Note that changing the child visibility of a widget does not queue a resize on the widget. Most of the time, the size of a widget is computed from all visible children, whether or not they are mapped. If this is not the case, the container can queue a resize itself.
This function is only useful for container implementations and should never be called by an application.
if %TRUE, widget should be mapped along with its parent.
Sets the allowlist for which
Cross-Origin Resource Sharing
checks are disabled in web_view. URI patterns must be of the form
[protocol]://[host]/[path], each component may contain the wildcard
character (*) to represent zero or more other characters. All three
components are required and must not be omitted from the URI
patterns.
Disabling CORS checks permits resources from other origins to load allowlisted resources. It does not permit the allowlisted resources to load resources from other origins.
If this function is called multiple times, only the allowlist set by the most recent call will be effective.
an allowlist of URI patterns, or %NULL
Clear all style classes applied to widget
and replace them with classes.
%NULL-terminated list of style classes to apply to widget.
Sets a named cursor to be shown when pointer devices point
towards widget.
This is a utility function that creates a cursor via
[ctorGdk.Cursor.new_from_name] and then sets it on widget
with [methodGtk.Widget.set_cursor]. See those functions for
details.
On top of that, this function allows name to be %NULL, which
will do the same as calling [methodGtk.Widget.set_cursor]
with a %NULL cursor.
The name of the cursor
Sets the current custom character encoding override of web_view. The custom
character encoding will override any text encoding detected via HTTP headers or
META tags. Calling this method will stop any current load operation and reload the
current page. Setting the custom character encoding to %NULL removes the character
encoding override.
a character encoding name or %NULL
Each object carries around a table of associations from strings to pointers. This function lets you set an association.
If the object already had an association with that name, the old association will be destroyed.
Internally, the key is converted to a #GQuark using g_quark_from_string().
This means a copy of key is kept permanently (even after object has been
finalized) — so it is recommended to only use a small, bounded set of values
for key in your program, to avoid the #GQuark storage growing unbounded.
name of the key
data to associate with that key
Sets the reading direction on a particular widget.
This direction controls the primary direction for widgets containing text, and also the direction in which the children of a container are packed. The ability to set the direction is present in order so that correct localization into languages with right-to-left reading directions can be done. Generally, applications will let the default reading direction present, except for containers where the containers are arranged in an order that is explicitly visual rather than logical (such as buttons for text justification).
If the direction is set to %GTK_TEXT_DIR_NONE, then the value
set by [funcGtk.Widget.set_default_direction] will be used.

Set the display capture state of a #WebKitWebView.
If #WebKitSettings:enable-mediastream is %FALSE, this method will have no visible effect. Once the state of the device has been set to %WEBKIT_MEDIA_CAPTURE_STATE_NONE it cannot be changed anymore. The page can however request capture again using the mediaDevices API.
a #WebKitMediaCaptureState
Sets whether the user is allowed to edit the HTML document.
If editable is %TRUE, web_view allows the user to edit the HTML document. If
editable is %FALSE, an element in web_view's document can only be edited if the
CONTENTEDITABLE attribute has been set on the element or one of its parent
elements. By default a #WebKitWebView is not editable.
Normally, a HTML document is not editable unless the elements within the document are editable. This function provides a way to make the contents of a #WebKitWebView editable without altering the document or DOM structure.
a #gboolean indicating the editable state
Set child as the current focus child of widget.
This function is only suitable for widget implementations.
If you want a certain widget to get the input focus, call
[methodGtk.Widget.grab_focus] on it.
Sets whether the widget should grab focus when it is clicked with the mouse.
Making mouse clicks not grab focus is useful in places like toolbars where you don’t want the keyboard focus removed from the main area of the application.
whether the widget should grab focus when clicked with the mouse
Specifies whether widget can own the input focus.
Widget implementations should set focusable to %TRUE in
their init() function if they want to receive keyboard input.
Note that having focusable be %TRUE is only one of the
necessary conditions for being focusable. A widget must
also be sensitive and can-focus and not have an ancestor
that is marked as not can-focus in order to receive input
focus.
See [methodGtk.Widget.grab_focus] for actually setting
the input focus on a widget.
whether or not widget can own the input focus
Sets the font map to use for Pango rendering.
The font map is the object that is used to look up fonts. Setting a custom font map can be useful in special situations, e.g. when you need to add application-specific fonts to the set of available fonts.
When not set, the widget will inherit the font map from its parent.
Sets the cairo_font_options_t used for Pango rendering
in this widget.
When not set, the default font options for the GdkDisplay
will be used.
a cairo_font_options_t to unset any previously set default font options
Sets the has-tooltip property on widget to has_tooltip.
whether or not widget has a tooltip.
Sets whether the widget would like any available extra horizontal space.
When a user resizes a GtkWindow, widgets with expand=TRUE
generally receive the extra space. For example, a list or
scrollable area or document in your window would often be set to
expand.
Call this function to set the expand flag if you would like your widget to become larger horizontally when the window has extra room.
By default, widgets automatically expand if any of their children
want to expand. (To see if a widget will automatically expand given
its current children and state, call [methodGtk.Widget.compute_expand].
A container can decide how the expandability of children affects the
expansion of the container by overriding the compute_expand virtual
method on GtkWidget.).
Setting hexpand explicitly with this function will override the automatic expand behavior.
This function forces the widget to expand or not to expand,
regardless of children. The override occurs because
[methodGtk.Widget.set_hexpand] sets the hexpand-set property (see
[methodGtk.Widget.set_hexpand_set]) which causes the widget’s hexpand
value to be used, rather than looking at children and widget state.
whether to expand
Sets whether the hexpand flag will be used.
The [propertyGtk.Widget:hexpand-set] property will be set
automatically when you call [methodGtk.Widget.set_hexpand]
to set hexpand, so the most likely reason to use this function
would be to unset an explicit expand flag.
If hexpand is set, then it overrides any computed expand value based on child widgets. If hexpand is not set, then the expand value depends on whether any children of the widget would like to expand.
There are few reasons to use this function, but it’s here for completeness and consistency.

Set the microphone capture state of a #WebKitWebView.
If #WebKitSettings:enable-mediastream is %FALSE, this method will have no visible effect. Once the state of the device has been set to %WEBKIT_MEDIA_CAPTURE_STATE_NONE it cannot be changed anymore. The page can however request capture again using the mediaDevices API.
a #WebKitMediaCaptureState
Sets a widgets name.
Setting a name allows you to refer to the widget from a
CSS file. You can apply a style to widgets with a particular name
in the CSS file. See the documentation for the CSS syntax (on the
same page as the docs for [classGtk.StyleContext].
Note that the CSS syntax has certain special characters to delimit and represent elements in a selector (period, #, >, *...), so using these will make your widget impossible to match by name. Any combination of alphanumeric symbols, dashes and underscores will suffice.
name for the widget
Request the widget to be rendered partially transparent.
An opacity of 0 is fully transparent and an opacity of 1 is fully opaque.
Opacity works on both toplevel widgets and child widgets, although there are some limitations: For toplevel widgets, applying opacity depends on the capabilities of the windowing system. On X11, this has any effect only on X displays with a compositing manager, see gdk_display_is_composited(). On Windows and Wayland it should always work, although setting a window’s opacity after the window has been shown may cause some flicker.
Note that the opacity is inherited through inclusion — if you set
a toplevel to be partially translucent, all of its content will
appear translucent, since it is ultimatively rendered on that
toplevel. The opacity value itself is not inherited by child
widgets (since that would make widgets deeper in the hierarchy
progressively more translucent). As a consequence, [classGtk.Popover]s
and other [ifaceGtk.Native] widgets with their own surface will use their
own opacity value, and thus by default appear non-translucent,
even if they are attached to a toplevel that is translucent.
desired opacity, between 0 and 1
Sets how widget treats content that is drawn outside the
widget's content area.
See the definition of [enumGtk.Overflow] for details.
This setting is provided for widget implementations and should not be used by application code.
The default value is %GTK_OVERFLOW_VISIBLE.
desired overflow
Sets parent as the parent widget of widget.
This takes care of details such as updating the state and style
of the child to reflect its new location and resizing the parent.
The opposite function is [methodGtk.Widget.unparent].
This function is useful only when implementing subclasses of
GtkWidget.
Sets a property on an object.
the name of the property to set

Specifies whether widget will be treated as the default
widget within its toplevel when it has the focus, even if
another widget is the default.
whether or not widget can be a default widget.
Sets the sensitivity of a widget.
A widget is sensitive if the user can interact with it. Insensitive widgets are “grayed out” and the user can’t interact with them. Insensitive widgets are known as “inactive”, “disabled”, or “ghosted” in some other toolkits.
%TRUE to make the widget sensitive
Sets the #WebKitSettings to be applied to web_view. The
existing #WebKitSettings of web_view will be replaced by
settings. New settings are applied immediately on web_view.
The same #WebKitSettings object can be shared
by multiple #WebKitWebViews.
Sets the minimum size of a widget.
That is, the widget’s size request will be at least width
by height. You can use this function to force a widget to
be larger than it normally would be.
In most cases, [methodGtk.Window.set_default_size] is a better
choice for toplevel windows than this function; setting the default
size will still allow users to shrink the window. Setting the size
request will force them to leave the window at least as large as
the size request.
Note the inherent danger of setting any fixed size - themes, translations into other languages, different fonts, and user action can all change the appropriate size for a given widget. So, it's basically impossible to hardcode a size that will always be correct.
The size request of a widget is the smallest size a widget can accept while still functioning well and drawing itself correctly. However in some strange cases a widget may be allocated less than its requested size, and in many cases a widget may be allocated more space than it requested.
If the size request in a given direction is -1 (unset), then the “natural” size request of the widget will be used instead.
The size request set here does not include any margin from the
properties
[propertyGtk.Widget:margin-start],
[propertyGtk.Widget:margin-end],
[propertyGtk.Widget:margin-top], and
[propertyGtk.Widget:margin-bottom], but it does include pretty
much all other padding or border properties set by any subclass
of GtkWidget.

Turns on flag values in the current widget state.
Typical widget states are insensitive, prelighted, etc.
This function accepts the values %GTK_STATE_FLAG_DIR_LTR and
%GTK_STATE_FLAG_DIR_RTL but ignores them. If you want to set
the widget's direction, use [methodGtk.Widget.set_direction].
This function is for use in widget implementations.

Sets markup as the contents of the tooltip, which is marked
up with Pango markup.

Sets the visibility state of widget.
Note that setting this to %TRUE doesn’t mean the widget is
actually viewable, see [methodGtk.Widget.get_visible].
This function simply calls [methodGtk.Widget.show] or
[methodGtk.Widget.hide] but is nicer to use when the
visibility of the widget depends on some condition.

Set the zoom level of web_view, i.e. the factor by which the
view contents are scaled with respect to their original size.

Returns whether widget should contribute to
the measuring and allocation of its parent.
This is %FALSE for invisible children, but also for children that have their own surface.
Flags a widget to be displayed.
Any widget that isn’t shown will not appear on the screen.
Remember that you have to show the containers containing a widget, in addition to the widget itself, before it will appear onscreen.
When a toplevel container is shown, it is immediately realized and mapped; other shown widgets are realized and mapped when their toplevel container is realized and mapped.
Snapshot the a child of widget.
When a widget receives a call to the snapshot function,
it must send synthetic [vfuncGtk.Widget.snapshot] calls
to all children. This function provides a convenient way
of doing this. A widget, when it receives a call to its
[vfuncGtk.Widget.snapshot] function, calls
gtk_widget_snapshot_child() once for each child, passing in
the snapshot the widget received.
gtk_widget_snapshot_child() takes care of translating the origin of
snapshot, and deciding whether the child needs to be snapshot.
This function does nothing for children that implement GtkNative.
a child of widget
GtkSnapshot as passed to the widget. In particular, no calls to gtk_snapshot_translate() or other transform calls should have been made.
Remove a specified datum from the object's data associations, without invoking the association's destroy handler.
name of the key
This function gets back user data pointers stored via
g_object_set_qdata() and removes the data from object
without invoking its destroy() function (if any was
set).
Usually, calling this function is only required to update
user data pointers with a destroy notifier, for example:
void
object_add_to_user_list (GObject *object,
const gchar *new_string)
{
// the quark, naming the object data
GQuark quark_string_list = g_quark_from_static_string ("my-string-list");
// retrieve the old string list
GList *list = g_object_steal_qdata (object, quark_string_list);
// prepend new string
list = g_list_prepend (list, g_strdup (new_string));
// this changed 'list', so we need to set it again
g_object_set_qdata_full (object, quark_string_list, list, free_string_list);
}
static void
free_string_list (gpointer data)
{
GList *node, *list = data;
for (node = list; node; node = node->next)
g_free (node->data);
g_list_free (list);
}
Using g_object_get_qdata() in the above example, instead of g_object_steal_qdata() would have left the destroy function set, and thus the partial string list would have been freed upon g_object_set_qdata_full().
A #GQuark, naming the user data pointer
Stops any ongoing loading operation in web_view.
This method does nothing if no content is being loaded.
If there is a loading operation in progress, it will be cancelled and
#WebKitWebView::load-failed signal will be emitted with
%WEBKIT_NETWORK_ERROR_CANCELLED error.
Terminates the web process associated to web_view. When the web process gets terminated
using this method, the #WebKitWebView::web-process-terminated signal is emitted with
%WEBKIT_WEB_PROCESS_TERMINATED_BY_API as the reason for termination.
Reverts the effect of a previous call to
g_object_freeze_notify(). The freeze count is decreased on object
and when it reaches zero, queued "notify" signals are emitted.
Duplicate notifications for each property are squashed so that at most one #GObject::notify signal is emitted for each property, in the reverse order in which they have been queued.
It is an error to call this function when the freeze count is zero.
Translate coordinates relative to src_widget’s allocation
to coordinates relative to dest_widget’s allocations.
In order to perform this operation, both widget must share a common ancestor.

Triggers a tooltip query on the display where the toplevel
of widget is located.
Tries to close the web_view. This will fire the onbeforeunload event
to ask the user for confirmation to close the page. If there isn't an
onbeforeunload event handler or the user confirms to close the page,
the #WebKitWebView::close signal is emitted, otherwise nothing happens.
Causes a widget to be unmapped if it’s currently mapped.
This function is only for use in widget implementations.
Dissociate widget from its parent.
This function is only for use in widget implementations, typically in dispose.
Causes a widget to be unrealized (frees all GDK resources associated with the widget).
This function is only useful in widget implementations.
Decreases the reference count of object. When its reference count
drops to 0, the object is finalized (i.e. its memory is freed).
If the pointer to the #GObject may be reused in future (for example, if it is an instance variable of another object), it is recommended to clear the pointer to %NULL rather than retain a dangling pointer to a potentially invalid #GObject instance. Use g_clear_object() for this.
Turns off flag values for the current widget state.

This function essentially limits the life time of the closure to
the life time of the object. That is, when the object is finalized,
the closure is invalidated by calling g_closure_invalidate() on
it, in order to prevent invocations of the closure with a finalized
(nonexisting) object. Also, g_object_ref() and g_object_unref() are
added as marshal guards to the closure, to ensure that an extra
reference count is held on object during invocation of the
closure. Usually, this function will be called on closures that
use this object as closure data.

Find the #GParamSpec with the given name for an

name of a property to look up.
Add a property to an interface; this is only useful for interfaces that are added to GObject-derived types. Adding a property to an interface forces all objects classes with that interface to have a compatible property. The compatible property could be a newly created #GParamSpec, but normally g_object_class_override_property() will be used so that the object class only needs to provide an implementation and inherits the property description, default value, bounds, and so forth from the interface property.
This function is meant to be called from the interface's default
vtable initialization function (the class_init member of
#GTypeInfo.) It must not be called after after class_init has
been called for any object types implementing this interface.

the #WebKitWebContext to be used by the #WebKitWebView
Creates a new #WebKitWebView sharing the same web process with web_view.
This method doesn't have any effect when %WEBKIT_PROCESS_MODEL_SHARED_SECONDARY_PROCESS
process model is used, because a single web process is shared for all the web views in the
same #WebKitWebContext. When using %WEBKIT_PROCESS_MODEL_MULTIPLE_SECONDARY_PROCESSES process model,
this method should always be used when creating the #WebKitWebView in the #WebKitWebView::create signal.
You can also use this method to implement other process models based on %WEBKIT_PROCESS_MODEL_MULTIPLE_SECONDARY_PROCESSES,
like for example, sharing the same web process for all the views in the same security domain.
The newly created #WebKitWebView will also have the same #WebKitUserContentManager,
