|

* @activate_signal: The signal to emit when a widget of this class is
|

* activated, gtk_widget_activate() handles the emission.
|
||
* Implementation of this signal is optional.
|
||
* @destroy: Signals that all holders of a reference to the widget
|
||
* should release the reference that they hold.
|
||
* @show: Signal emitted when widget is shown
|
||
* @hide: Signal emitted when widget is hidden.
|
||
* @map: Signal emitted when widget is going to be mapped, that is
|
||
* when the widget is visible (which is controlled with
|
||
* gtk_widget_set_visible()) and all its parents up to the toplevel
|
||
* widget are also visible.
|
||
* @unmap: Signal emitted when widget is going to be unmapped, which
|
||
* 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
|
||
* #GdkSurface, which means that gtk_widget_realize() has been called or
|
||
* the widget has been mapped (that is, it is going to be drawn).
|
||
* @unrealize: Signal emitted when the GdkSurface associated with
|
||
* widget is destroyed, which means that gtk_widget_unrealize() has
|
||
* been called or the widget has been unmapped (that is, it is going
|
||
* to be hidden).
|
||
* @root: Called when the widget gets added to a #GtkRoot widget. Must chain up
|
||
* @unroot: Called when the widget is about to be removed from its #GtkRoot widget. Must chain up
|
||
* @size_allocate: Signal emitted to get the widget allocation.
|
||
* @state_flags_changed: Signal emitted when the widget state changes,
|
||
* see gtk_widget_get_state_flags().
|
||
* @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.
|
||
* @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.measure() called first to get the default width (passing
|
||
* a for_size of -1), then again to get the height for said default width.
|
||
* %GTK_SIZE_REQUEST_CONSTANT_SIZE disables any height-for-width or
|
||
* width-for-height geometry management for said widget and is the
|
||
* default return.
|
||
* It’s important to note that any widget
|
||
* which trades height-for-width or width-for-height must respond properly
|
||
* to a for_size value >= -1 passed to #GtkWidgetClass.measure, for both
|
||
* possible orientations.
|
||
* @measure: This is called by containers to obtain the minimum and natural
|
||
* size of the widget. Depending on the orientation parameter, the passed
|
||
* for_size can be interpreted as width or height. A widget will never be
|
||
* allocated less than its minimum size.
|
||
* @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.
|
||
* @popup_menu: Signal emitted whenever a widget should pop up a
|
||
* context menu.
|
||
* @get_accessible: Returns the accessible object that describes the
|
||
* widget to an assistive technology.
|
||
* @can_activate_accel: Signal allows applications and derived widgets
|
||
* to override the default GtkWidget handling for determining whether
|
||
* an accelerator can be activated.
|
||
* @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.
|
||
* @css_changed: Signal emitted when the CSS used by widget was changed. Widgets
|
||
* should then discard their caches that depend on CSS and queue resizes or
|
||
* redraws accordingly. The default implementation will take care of this for
|
||
* all the default CSS properties, so implementations must chain up.
|
||
* @snapshot: Vfunc for gtk_widget_snapshot().
|
||
* @contains: Vfunc for gtk_widget_contains().
