Custom title widget to display.
The decoration layout for buttons.
If this property is not set, the
[propertyGtk.Settings:gtk-decoration-layout] setting is used.
There can be valid reasons for overriding the setting, such as a header bar design that does not allow for buttons to take room on the right, or only offers room for a single close button. Split header bars are another example for overriding the setting.
The format of the string is button names, separated by commas. A colon separates the buttons that should appear on the start from those on the end. Recognized button names are minimize, maximize, close, icon (the window icon) and menu (a menu button for the fallback app menu).
For example, “menu:minimize,maximize,close” specifies a menu on the left, and minimize, maximize and close buttons on the right.
Whether [propertyHeaderBar:decoration-layout] is set.
Whether the widget is double buffered.
Whether to expand in both directions. Setting this sets both #GtkWidget:hexpand and #GtkWidget:vexpand
Whether the widget should grab focus when it is clicked with the mouse.
This property is only relevant for widgets that can take focus.
Before 3.20, several widgets (GtkButton, GtkFileChooserButton, GtkComboBox) implemented this property individually.
How to distribute horizontal space if widget gets extra space, see #GtkAlign
Whether to reserve space for a subtitle, even if none is currently set.
Enables or disables the emission of #GtkWidget::query-tooltip on widget.
A value of %TRUE indicates that widget can have a tooltip, in this case
the widget will be queried using #GtkWidget::query-tooltip to determine
whether it will provide a tooltip or not.
Note that setting this property to %TRUE for the first time will change the event masks of the GdkWindows of this widget to include leave-notify and motion-notify events. This cannot and will not be undone when the property is set to %FALSE again.
Whether to expand horizontally. See gtk_widget_set_hexpand().
Whether to use the #GtkWidget:hexpand property. See gtk_widget_get_hexpand_set().
Whether the size should smoothly change when changing between children.
If TRUE, the header bar will interpolate its size between the one of the
previous visible child and the one of the new visible child, according to
the set transition duration and the orientation, e.g. if the orientation is
horizontal, it will interpolate the its height.
Sets all four sides' margin at once. If read, returns max margin on any side.
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 gtk_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 gtk_widget_set_size_request() for example.
Margin on left 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 gtk_widget_set_size_request() for example.
Margin on right 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 gtk_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 gtk_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 gtk_widget_set_size_request() for example.
The requested opacity of the widget. See gtk_widget_set_opacity() for more details about window opacity.
Before 3.8 this was only available in GtkWindow
Whether to show window decorations.
Which buttons are actually shown and where is determined by the
[propertyHeaderBar:decoration-layout] property, and by the state of the
window (e.g. a close button will not be shown if the window can't be
closed).
The amount of space between children.
The style of the widget, which contains information about how it will look (colors, etc).
The subtitle to display.
The title to display.
Sets the text of tooltip to be the given string, which is marked up with the [Pango text markup language][PangoMarkupFormat]. Also see gtk_tooltip_set_markup().
This is a convenience property which will take care of getting the tooltip shown if the given string is not %NULL: #GtkWidget:has-tooltip will automatically be set to %TRUE and there will be taken care of #GtkWidget::query-tooltip in the default signal handler.
Note that if both #GtkWidget:tooltip-text and #GtkWidget:tooltip-markup are set, the last one wins.
Sets the text of tooltip to be the given string.
Also see gtk_tooltip_set_text().
This is a convenience property which will take care of getting the tooltip shown if the given string is not %NULL: #GtkWidget:has-tooltip will automatically be set to %TRUE and there will be taken care of #GtkWidget::query-tooltip in the default signal handler.
Note that if both #GtkWidget:tooltip-text and #GtkWidget:tooltip-markup are set, the last one wins.
The transition duration, in milliseconds.
How to distribute vertical space if widget gets extra space, see #GtkAlign
Whether to expand vertically. See gtk_widget_set_vexpand().
Whether to use the #GtkWidget:vexpand property. See gtk_widget_get_vexpand_set().
The policy for aligning the center widget.
