* means that either it or any of its parents up to the toplevel
|
|
* widget have been set as hidden.
|
|
* @realize: Signal emitted when widget is associated with a
|
|
* #GdkWindow, which means that gtk_widget_realize() has been called or
|
|
* the widget has been mapped (that is, it is going to be drawn).
|
|

|
|
* @size_allocate: Signal emitted to get the widget allocation.
|
|
* @state_changed: Signal emitted when the widget state
|
|
* changes. Deprecated: 3.0
|
|
* @state_flags_changed: Signal emitted when the widget state changes,
|

* see gtk_widget_get_state_flags().
|
|
* @parent_set: Signal emitted when a new parent has been set on a
|
|
* widget.
|
|
* @hierarchy_changed: Signal emitted when the anchored state of a
|
|
* widget changes.
|
|
* @style_set: Signal emitted when a new style has been set on a
|
|
* widget. Deprecated: 3.0
|
|
* @direction_changed: Signal emitted when the text direction of a
|
|
* widget changes.
|
|
* @grab_notify: Signal emitted when a widget becomes shadowed by a
|
|
* GTK+ grab (not a pointer or keyboard grab) on another widget, or
|
|
* when it becomes unshadowed due to a grab being removed.
|
|
* @child_notify: Signal emitted for each child property that has
|
|
* changed on an object.
|
|
* @draw: Signal emitted when a widget is supposed to render itself.
|
|
* @get_request_mode: This allows a widget to tell its parent container whether
|
|
* it prefers to be allocated in %GTK_SIZE_REQUEST_HEIGHT_FOR_WIDTH or
|
|
* %GTK_SIZE_REQUEST_WIDTH_FOR_HEIGHT mode.
|
|
* %GTK_SIZE_REQUEST_HEIGHT_FOR_WIDTH means the widget prefers to have
|
|
* #GtkWidgetClass.get_preferred_width() called and then
|
|
* #GtkWidgetClass.get_preferred_height_for_width().
|
|
* %GTK_SIZE_REQUEST_CONSTANT_SIZE disables any height-for-width or
|
|
* width-for-height geometry management for a said widget and is the
|
|
* default return.
|
|
* It's important to note (as described below) that any widget
|
|
* which trades height-for-width or width-for-height must respond properly
|
|
* to both of the virtual methods #GtkWidgetClass.get_preferred_height_for_width()
|
|
* and #GtkWidgetClass.get_preferred_width_for_height() since it might be
|
|
* queried in either #GtkSizeRequestMode by its parent container.
|
|
* @get_preferred_height: This is called by containers to obtain the minimum
|
|
* and natural height of a widget. A widget that does not actually trade
|
|
* any height for width or width for height only has to implement these
|
|
* two virtual methods (#GtkWidgetClass.get_preferred_width() and
|
|
* #GtkWidgetClass.get_preferred_height()).
|
|
* @get_preferred_width_for_height: This is analogous to
|
|
* #GtkWidgetClass.get_preferred_height_for_width() except that it
|
|
* operates in the oposite orientation. It's rare that a widget actually
|
|
* does %GTK_SIZE_REQUEST_WIDTH_FOR_HEIGHT requests but this can happen
|
|
* when, for example, a widget or container gets additional columns to
|
|
* compensate for a smaller allocated height.
|
|
* @get_preferred_width: This is called by containers to obtain the minimum
|
|
* and natural width of a widget. A widget will never be allocated a width
|
|
* less than its minimum and will only ever be allocated a width greater
|
|
* than the natural width once all of the said widget's siblings have
|
|
* received their natural widths.
|
|
* Furthermore, a widget will only ever be allocated a width greater than
|
|
* its natural width if it was configured to receive extra expand space
|
|
* from its parent container.
|
|
* @get_preferred_height_for_width: This is similar to
|
|
* #GtkWidgetClass.get_preferred_height() except that it is passed a
|
|
* contextual width to request height for. By implementing this virtual
|
|
* method it is possible for a #GtkLabel to tell its parent how much height
|
|
* would be required if the label were to be allocated a said width.
|
|
* @mnemonic_activate: Activates the @widget if @group_cycling is
|
|
* %FALSE, and just grabs the focus if @group_cycling is %TRUE.
|
|
* @grab_focus: Causes @widget to have the keyboard focus for the
|
|
* #GtkWindow it's inside.
|
|
* @focus:
|
|
* @move_focus: Signal emitted when a change of focus is requested
|
|
* @keynav_failed: Signal emitted if keyboard navigation fails.
|
|
* @event: The GTK+ main loop will emit three signals for each GDK
|
|
* event delivered to a widget: one generic ::event signal, another,
|
|
* more specific, signal that matches the type of event delivered
|
|
* (e.g. "key-press-event") and finally a generic "event-after"
|
|
* signal.
|
|
* @button_press_event: Signal will be emitted when a button
|
|
* (typically from a mouse) is pressed.
|
|
* @button_release_event: Signal will be emitted when a button
|
|
* (typically from a mouse) is released.
|
|
* @scroll_event: Signal emitted when a button in the 4 to 7 range is
|
|
* pressed.
|
|
* @motion_notify_event: Signal emitted when the pointer moves over
|
|
* the widget's #GdkWindow.
|
|
* @delete_event: Signal emitted if a user requests that a toplevel
|
|
* window is closed.
|
|
* @destroy_event: Signal is emitted when a #GdkWindow is destroyed.
|
|
* @key_press_event: Signal emitted when a key is pressed.
|
|
* @key_release_event: Signal is emitted when a key is released.
|
|
* @enter_notify_event: Signal event will be emitted when the pointer
|
|
* enters the widget's window.
|
|
* @leave_notify_event: Will be emitted when the pointer leaves the
|
|
* widget's window.
|
|
* @configure_event: Signal will be emitted when the size, position or
|
|
* stacking of the widget's window has changed.
|
|
* @focus_in_event: Signal emitted when the keyboard focus enters the
|
|
* widget's window.
|
|
* @focus_out_event: Signal emitted when the keyboard focus leaves the
|
|
* widget's window.
|
|
* @map_event: Signal emitted when the widget's window is mapped.
|
|
* @unmap_event: Signal will be emitted when the widget's window is
|
|
* unmapped.
|
|
* @property_notify_event: Signal will be emitted when a property on
|
|
* the widget's window has been changed or deleted.
|
|
* @selection_clear_event: Signal will be emitted when the the
|
|
* widget's window has lost ownership of a selection.
|
|
* @selection_request_event: Signal will be emitted when another
|
|
* client requests ownership of the selection owned by the widget's
|
|
* window.
|
|
* @selection_notify_event:
|
|
* @proximity_in_event:
|
|
* @proximity_out_event:
|
|
* @visibility_notify_event: Signal emitted when the widget's window is
|
|
* obscured or unobscured.
|
|
* @window_state_event: Signal emitted when the state of the toplevel
|
|
* window associated to the widget changes.
|
|
* @damage_event: Signal emitted when a redirected window belonging to
|
|
* widget gets drawn into.
|
|
* @grab_broken_event: Signal emitted when a pointer or keyboard grab
|
|
* on a window belonging to widget gets broken.
|
|
* @selection_get:
|
|
* @selection_received:
|
|
* @drag_begin: Signal emitted on the drag source when a drag is
|
|
* started.
|
|
* @drag_end: Signal emitted on the drag source when a drag is
|
|
* finished.
|
|
* @drag_data_get: Signal emitted on the drag source when the drop
|
|
* site requests the data which is dragged.
|
|
* @drag_data_delete: Signal emitted on the drag source when a drag
|
|
* with the action %GDK_ACTION_MOVE is successfully completed.
|
|
* @drag_leave: Signal emitted on the drop site when the cursor leaves
|
|
* the widget.
|
|
* @drag_motion: signal emitted on the drop site when the user moves
|
|
* the cursor over the widget during a drag.
|
|
* @drag_drop: Signal emitted on the drop site when the user drops the
|
|
* data onto the widget.
|
|
* @drag_data_received: Signal emitted on the drop site when the
|
|
* dragged data has been received.
|
|
* @drag_failed: Signal emitted on the drag source when a drag has
|
|
* failed.
|
|
* @popup_menu: Signal emitted whenever a widget should pop up a
|
|
* context menu.
|
|
* @show_help:
|
|
* @get_accessible: Returns the accessible object that describes the
|
|
* widget to an assistive technology.
|
|
* @screen_changed: Signal emitted when the screen of a widget has
|
|
* changed.
|
|
* @can_activate_accel: Signal allows applications and derived widgets
|
|
* to override the default GtkWidget handling for determining whether
|
|
* an accelerator can be activated.
|
|
* @composited_changed: Signal emitted when the composited status of
|
|
* widgets screen changes. See gdk_screen_is_composited().
|
|
* @query_tooltip: Signal emitted when "has-tooltip" is %TRUE and the
|
|
* hover timeout has expired with the cursor hovering "above"
|
|
* widget; or emitted when widget got focus in keyboard mode.
|
|
* @compute_expand: Computes whether a container should give this
|
|
* widget extra space when possible.
|
|
* @adjust_size_request: Convert an initial size request from a widget's
|
|
* #GtkSizeRequestMode virtual method implementations into a size request to
|
|
* be used by parent containers in laying out the widget.
|
|
* adjust_size_request adjusts <emphasis>from</emphasis> a child widget's
|
|
* original request <emphasis>to</emphasis> what a parent container should
|
|
* use for layout. The @for_size argument will be -1 if the request should
|
|
* not be for a particular size in the opposing orientation, i.e. if the
|
|
* request is not height-for-width or width-for-height. If @for_size is
|
|
* greater than -1, it is the proposed allocation in the opposing
|
|
* orientation that we need the request for. Implementations of
|
|
* adjust_size_request should chain up to the default implementation,
|
|
* which applies #GtkWidget's margin properties and imposes any values
|
|
* from gtk_widget_set_size_request(). Chaining up should be last,
|
|
* <emphasis>after</emphasis> your subclass adjusts the request, so
|
|
* #GtkWidget can apply constraints and add the margin properly.
|
|
* @adjust_size_allocation: Convert an initial size allocation assigned
|
|
* by a #GtkContainer using gtk_widget_size_allocate(), into an actual
|
|
* size allocation to be used by the widget. adjust_size_allocation
|
|
* adjusts <emphasis>to</emphasis> a child widget's actual allocation
|
|
* <emphasis>from</emphasis> what a parent container computed for the
|
|
* child. The adjusted allocation must be entirely within the original
|
|
* allocation. In any custom implementation, chain up to the default
|
|
* #GtkWidget implementation of this method, which applies the margin
|
|
* and alignment properties of #GtkWidget. Chain up
|
|
* <emphasis>before</emphasis> performing your own adjustments so your
|
|
* own adjustments remove more allocation after the #GtkWidget base
|
|
* class has already removed margin and alignment. The natural size
|
|
* passed in should be adjusted in the same way as the allocated size,
|
|
* which allows adjustments to perform alignments or other changes
|
|
* based on natural size.
|
|
* @style_updated: Signal emitted when the GtkStyleContext of a widget
|
|
* is changed.
|
|
* @touch_event:
|
|
* @get_preferred_height_and_baseline_for_width:
|
|
* @adjust_baseline_request:
|
|
* @adjust_baseline_allocation:
|
|
* @queue_draw_region: Invalidates the area of widget defined by
|
|
* region by calling gdk_window_invalidate_region() on the widget's
|
|
* window and all its child windows.

* @member_name: name of the instance private member on the private struct for @data_type
|
|
*
|
|
* Binds a child widget defined in a template to the @widget_class, and
|
|
* also makes it available as an internal child in GtkBuilder, under the
|
|
* name @member_name.
|
|
*
|
|
* This macro is a convenience wrapper around the
|
|
* gtk_widget_class_bind_template_child_full() function.
|
|
*
|
|
* This macro will use the offset of the @member_name inside the @TypeName
|
|
* private data structure.
