The #ClutterTableLayout structure contains only private data and should be accessed using the provided API

Hierarchy

Index

Constructors

Properties

columnSpacing: number

The spacing between columns of the #ClutterTableLayout, in pixels

easingDuration: number

The duration of the animations, in case #ClutterTableLayout:use-animations is set to %TRUE.

The duration is expressed in milliseconds.

easingMode: number

The easing mode for the animations, in case #ClutterTableLayout:use-animations is set to %TRUE.

The easing mode has the same semantics of #ClutterAnimation:mode: it can either be a value from the #ClutterAnimationMode enumeration, like %CLUTTER_EASE_OUT_CUBIC, or a logical id as returned by clutter_alpha_register_func().

The default value is %CLUTTER_EASE_OUT_CUBIC.

gTypeInstance: TypeInstance
rowSpacing: number

The spacing between rows of the #ClutterTableLayout, in pixels

useAnimations: boolean

Whether the #ClutterTableLayout should animate changes in the layout properties.

By default, #ClutterTableLayout will honour the easing state of the children when allocating them. Setting this property to %TRUE will override the easing state with the layout manager's #ClutterTableLayout:easing-mode and #ClutterTableLayout:easing-duration properties.

name: string

Methods

  • beginAnimation(duration: number, mode: number): Alpha
  • Begins an animation of duration milliseconds, using the provided easing mode

    The easing mode can be specified either as a #ClutterAnimationMode or as a logical id returned by clutter_alpha_register_func()

    The result of this function depends on the manager implementation

    Parameters

    • duration: number

      the duration of the animation, in milliseconds

    • mode: number

      the easing mode of the animation

    Returns Alpha

  • 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.

    Parameters

    • sourceProperty: string

      the property on source to bind

    • target: GObject.Object

      the target #GObject

    • targetProperty: string

      the property on target to bind

    • flags: BindingFlags

      flags to pass to #GBinding

    Returns Binding

  • 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.

    This function is the language bindings friendly version of g_object_bind_property_full(), using #GClosures instead of function pointers.

    Parameters

    • sourceProperty: string

      the property on source to bind

    • target: GObject.Object

      the target #GObject

    • targetProperty: string

      the property on target to bind

    • flags: BindingFlags

      flags to pass to #GBinding

    • transformTo: TClosure<any, any>

      a #GClosure wrapping the transformation function from the source to the target, or %NULL to use the default

    • transformFrom: TClosure<any, any>

      a #GClosure wrapping the transformation function from the target to the source, or %NULL to use the default

    Returns Binding

  • emit(sigName: "notify::easing-duration", ...args: any[]): void
  • emit(sigName: "notify::easing-mode", ...args: any[]): void

  • emit(sigName: "notify::use-animations", ...args: any[]): void
  • emit(sigName: string, ...args: any[]): void
  • endAnimation(): void
  • forceFloating(): void
  • 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().

    Returns void

  • freezeNotify(): void
  • 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.

    Returns void

  • getAnimationProgress(): number
  • Retrieves the progress of the animation, if one has been started by clutter_layout_manager_begin_animation()

    The returned value has the same semantics of the #ClutterAlpha:alpha value

    Returns number

  • getColumnCount(): number
  • getColumnSpacing(): number
  • Retrieves the spacing set using clutter_table_layout_set_column_spacing()

    Returns number

  • getData(key?: string): object
  • Gets a named field from the objects table of associations (see g_object_set_data()).

    Parameters

    • Optional key: string

      name of the key for that association

    Returns object

  • getEasingDuration(): number
  • Retrieves the duration set using clutter_table_layout_set_easing_duration()

    Returns number

  • getEasingMode(): number
  • Retrieves the easing mode set using clutter_table_layout_set_easing_mode()

    Returns number

  • Retrieves the horizontal and vertical expand policies for actor as set using clutter_table_layout_pack() or clutter_table_layout_set_expand()

    Parameters

    Returns [boolean, boolean]

  • Retrieves the horizontal and vertical fill policies for actor as set using clutter_table_layout_pack() or clutter_table_layout_set_fill()

    Parameters

    Returns [boolean, boolean]

  • getPreferredHeight(container: Clutter.Container, forWidth: number): [number, number]
  • Computes the minimum and natural heights of the container according to manager.

    See also clutter_actor_get_preferred_height()

    Parameters

    • container: Clutter.Container

      the #ClutterContainer using manager

    • forWidth: number

      the width for which the height should be computed, or -1

    Returns [number, number]

  • getPreferredWidth(container: Clutter.Container, forHeight: number): [number, number]
  • Computes the minimum and natural widths of the container according to manager.

    See also clutter_actor_get_preferred_width()

    Parameters

    • container: Clutter.Container

      the #ClutterContainer using manager

    • forHeight: number

      the height for which the width should be computed, or -1

    Returns [number, number]

  • getProperty(propertyName?: string, value?: any): void
  • Gets a property of an object.

    The value can be:

    • an empty #GValue initialized by %G_VALUE_INIT, which will be automatically initialized with the expected type of the property (since GLib 2.60)
    • a #GValue initialized with the expected type of the property
    • a #GValue initialized with a type to which the expected type of the property can be transformed

    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.

    Parameters

    • Optional propertyName: string

      the name of the property to get

    • Optional value: any

      return location for the property value

    Returns void

  • getQdata(quark: number): object
  • This function gets back user data pointers stored via g_object_set_qdata().

    Parameters

    • quark: number

      A #GQuark, naming the user data pointer

    Returns object

  • getRowCount(): number
  • getRowSpacing(): number
  • Retrieves the spacing set using clutter_table_layout_set_row_spacing()

    Returns number

  • Retrieves the row and column span for actor as set using clutter_table_layout_pack() or clutter_table_layout_set_span()

    Parameters

    Returns [number, number]

  • getUseAnimations(): boolean
  • Retrieves whether layout should animate changes in the layout properties

    Since clutter_table_layout_set_use_animations()

    Returns boolean

  • getv(names: string[], values: any[]): void
  • 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.

    Parameters

    • names: string[]

      the names of each property to get

    • values: any[]

      the values of each property to get

    Returns void

  • isFloating(): boolean
  • layoutChanged(): void
  • Emits the #ClutterLayoutManager::layout-changed signal on manager

    This function should only be called by implementations of the #ClutterLayoutManager class

    Returns void

  • notify(propertyName: string): void
  • 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.

    Parameters

    • propertyName: string

      the name of a property installed on the class of object.

    Returns void

  • 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]);
    

    Parameters

    • pspec: ParamSpec

      the #GParamSpec of a property installed on the class of object.

  • pack(actor: Clutter.Actor, column: number, row: number): void
  • Packs actor inside the #ClutterContainer associated to layout at the given row and column.

    Parameters

    • actor: Clutter.Actor

      a #ClutterActor

    • column: number

      the column the actor should be put, or -1 to append

    • row: number

      the row the actor should be put, or -1 to append

    Returns void

  • Increases the reference count of object.

    Since GLib 2.56, if GLIB_VERSION_MAX_ALLOWED is 2.56 or greater, the type of object will be propagated to the return type (using the GCC typeof() extension), so any casting the caller needs to do on the return type must be explicit.

    Returns GObject.Object

  • 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().

    Returns GObject.Object

  • runDispose(): void
  • Releases all references to other objects. This can be used to break reference cycles.

    This function should only be called from object system implementations.

    Returns void

  • setColumnSpacing(spacing: number): void
  • Sets the spacing between columns of layout

    Parameters

    • spacing: number

      the spacing between columns of the layout, in pixels

    Returns void

  • If the #ClutterLayoutManager sub-class allows it, allow adding a weak reference of the container using manager from within the layout manager

    The layout manager should not increase the reference count of the container

    Parameters

    Returns void

  • setData(key: string, data?: object): void
  • 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.

    Parameters

    • key: string

      name of the key

    • Optional data: object

      data to associate with that key

    Returns void

  • setEasingDuration(msecs: number): void
  • Sets the duration of the animations used by layout when animating changes in the layout properties

    Use clutter_table_layout_set_use_animations() to enable and disable the animations

    Parameters

    • msecs: number

      the duration of the animations, in milliseconds

    Returns void

  • setEasingMode(mode: number): void
  • Sets the easing mode to be used by layout when animating changes in layout properties

    Use clutter_table_layout_set_use_animations() to enable and disable the animations

    Parameters

    • mode: number

      an easing mode, either from #ClutterAnimationMode or a logical id from clutter_alpha_register_func()

    Returns void

  • setExpand(actor: Clutter.Actor, xExpand: boolean, yExpand: boolean): void
  • Sets the horizontal and vertical expand policies for actor inside layout

    Parameters

    • actor: Clutter.Actor

      a #ClutterActor child of layout

    • xExpand: boolean

      whether actor should allocate extra space horizontally

    • yExpand: boolean

      whether actor should allocate extra space vertically

    Returns void

  • setFill(actor: Clutter.Actor, xFill: boolean, yFill: boolean): void
  • Sets the horizontal and vertical fill policies for actor inside layout

    Parameters

    • actor: Clutter.Actor

      a #ClutterActor child of layout

    • xFill: boolean

      whether actor should fill horizontally the allocated space

    • yFill: boolean

      whether actor should fill vertically the allocated space

    Returns void

  • setProperty(propertyName: string, value?: any): void
  • setRowSpacing(spacing: number): void
  • Sets the spacing between rows of layout

    Parameters

    • spacing: number

      the spacing between rows of the layout, in pixels

    Returns void

  • setSpan(actor: Clutter.Actor, columnSpan: number, rowSpan: number): void
  • Sets the row and column span for actor inside layout

    Parameters

    • actor: Clutter.Actor

      a #ClutterActor child of layout

    • columnSpan: number

      Column span for actor

    • rowSpan: number

      Row span for actor

    Returns void

  • setUseAnimations(animate: boolean): void
  • Sets whether layout should animate changes in the layout properties

    The duration of the animations is controlled by clutter_table_layout_set_easing_duration(); the easing mode to be used by the animations is controlled by clutter_table_layout_set_easing_mode()

    Parameters

    • animate: boolean

      %TRUE if the layout should use animations

    Returns void

  • stealData(key?: string): object
  • Remove a specified datum from the object's data associations, without invoking the association's destroy handler.

    Parameters

    • Optional key: string

      name of the key

    Returns object

  • stealQdata(quark: number): object
  • 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().

    Parameters

    • quark: number

      A #GQuark, naming the user data pointer

    Returns object

  • thawNotify(): void
  • 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.

    Returns void

  • unref(): void
  • 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.

    Returns void

  • watchClosure(closure: TClosure<any, any>): void
  • 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.

    Parameters

    • closure: TClosure<any, any>

      #GClosure to watch

    Returns void

  • compatControl(what: number, data: object): number
  • Find the #GParamSpec with the given name for an interface. Generally, the interface vtable passed in as g_iface will be the default vtable from g_type_default_interface_ref(), or, if you know the interface has already been loaded, g_type_default_interface_peek().

    Parameters

    • gIface: TypeInterface

      any interface vtable for the interface, or the default vtable for the interface

    • propertyName: string

      name of a property to look up.

    Returns ParamSpec

  • 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.

    If pspec is a floating reference, it will be consumed.

    Parameters

    • gIface: TypeInterface

      any interface vtable for the interface, or the default vtable for the interface.

    • pspec: ParamSpec

      the #GParamSpec for the new property

    Returns void

  • Lists the properties of an interface.Generally, the interface vtable passed in as g_iface will be the default vtable from g_type_default_interface_ref(), or, if you know the interface has already been loaded, g_type_default_interface_peek().

    Parameters

    • gIface: TypeInterface

      any interface vtable for the interface, or the default vtable for the interface

    Returns ParamSpec[]

  • Creates a new instance of a #GObject subtype and sets its properties.

    Construction parameters (see %G_PARAM_CONSTRUCT, %G_PARAM_CONSTRUCT_ONLY) which are not explicitly specified are set to their default values.

    Parameters

    • objectType: GType<unknown>

      the type id of the #GObject subtype to instantiate

    • parameters: GObject.Parameter[]

      an array of #GParameter

    Returns GObject.Object
