/**
- * SECTION:gtkgesture
- * @Short_description: Base class for gestures
- * @Title: GtkGesture
- * @See_also: #GtkEventController, #GtkGestureSingle
+ * GtkGesture:
*
- * #GtkGesture is the base object for gesture recognition, although this
- * object is quite generalized to serve as a base for multi-touch gestures,
- * it is suitable to implement single-touch and pointer-based gestures (using
- * the special %NULL #GdkEventSequence value for these).
+ * `GtkGesture` is the base class for gesture recognition.
*
- * The number of touches that a #GtkGesture need to be recognized is controlled
- * by the #GtkGesture:n-points property, if a gesture is keeping track of less
- * or more than that number of sequences, it won't check whether the gesture
- * is recognized.
+ * Although `GtkGesture` is quite generalized to serve as a base for
+ * multi-touch gestures, it is suitable to implement single-touch and
+ * pointer-based gestures (using the special %NULL `GdkEventSequence`
+ * value for these).
+ *
+ * The number of touches that a `GtkGesture` need to be recognized is
+ * controlled by the [property@Gtk.Gesture:n-points] property, if a
+ * gesture is keeping track of less or more than that number of sequences,
+ * it won't check whether the gesture is recognized.
*
* As soon as the gesture has the expected number of touches, it will check
* regularly if it is recognized, the criteria to consider a gesture as
- * "recognized" is left to #GtkGesture subclasses.
+ * "recognized" is left to `GtkGesture` subclasses.
*
* A recognized gesture will then emit the following signals:
- * - #GtkGesture::begin when the gesture is recognized.
- * - A number of #GtkGesture::update, whenever an input event is processed.
- * - #GtkGesture::end when the gesture is no longer recognized.
+ *
+ * - [signal@Gtk.Gesture::begin] when the gesture is recognized.
+ * - [signal@Gtk.Gesture::update], whenever an input event is processed.
+ * - [signal@Gtk.Gesture::end] when the gesture is no longer recognized.
*
* ## Event propagation
*
* In order to receive events, a gesture needs to set a propagation phase
- * through gtk_event_controller_set_propagation_phase().
- *
- * In the capture phase, events are propagated from the toplevel down to the
- * target widget, and gestures that are attached to containers above the widget
- * get a chance to interact with the event before it reaches the target.
- *
- * In the bubble phase, events are propagated up from the target widget to the
- * toplevel, and gestures that are attached to containers above the widget get
- * a chance to interact with events that have not been handled yet.
- *
- * ## States of a sequence # {#touch-sequence-states}
- *
- * Whenever input interaction happens, a single event may trigger a cascade of
- * #GtkGestures, both across the parents of the widget receiving the event and
- * in parallel within an individual widget. It is a responsibility of the
- * widgets using those gestures to set the state of touch sequences accordingly
- * in order to enable cooperation of gestures around the #GdkEventSequences
- * triggering those.
- *
- * Within a widget, gestures can be grouped through gtk_gesture_group(),
- * grouped gestures synchronize the state of sequences, so calling
- * gtk_gesture_set_sequence_state() on one will effectively propagate
+ * through [method@Gtk.EventController.set_propagation_phase].
+ *
+ * In the capture phase, events are propagated from the toplevel down
+ * to the target widget, and gestures that are attached to containers
+ * above the widget get a chance to interact with the event before it
+ * reaches the target.
+ *
+ * In the bubble phase, events are propagated up from the target widget
+ * to the toplevel, and gestures that are attached to containers above
+ * the widget get a chance to interact with events that have not been
+ * handled yet.
+ *
+ * ## States of a sequence
+ *
+ * Whenever input interaction happens, a single event may trigger a cascade
+ * of `GtkGesture`s, both across the parents of the widget receiving the
+ * event and in parallel within an individual widget. It is a responsibility
+ * of the widgets using those gestures to set the state of touch sequences
+ * accordingly in order to enable cooperation of gestures around the
+ * `GdkEventSequence`s triggering those.
+ *
+ * Within a widget, gestures can be grouped through [method@Gtk.Gesture.group].
+ * Grouped gestures synchronize the state of sequences, so calling
+ * [method@Gtk.Gesture.set_sequence_state] on one will effectively propagate
* the state throughout the group.
*
- * By default, all sequences start out in the #GTK_EVENT_SEQUENCE_NONE state,
+ * By default, all sequences start out in the %GTK_EVENT_SEQUENCE_NONE state,
* sequences in this state trigger the gesture event handler, but event
* propagation will continue unstopped by gestures.
*
- * If a sequence enters into the #GTK_EVENT_SEQUENCE_DENIED state, the gesture
+ * If a sequence enters into the %GTK_EVENT_SEQUENCE_DENIED state, the gesture
* group will effectively ignore the sequence, letting events go unstopped
* through the gesture, but the "slot" will still remain occupied while
* the touch is active.
*
- * If a sequence enters in the #GTK_EVENT_SEQUENCE_CLAIMED state, the gesture
+ * If a sequence enters in the %GTK_EVENT_SEQUENCE_CLAIMED state, the gesture
* group will grab all interaction on the sequence, by:
- * - Setting the same sequence to #GTK_EVENT_SEQUENCE_DENIED on every other gesture
- * group within the widget, and every gesture on parent widgets in the propagation
- * chain.
- * - calling #GtkGesture::cancel on every gesture in widgets underneath in the
- * propagation chain.
+ *
+ * - Setting the same sequence to %GTK_EVENT_SEQUENCE_DENIED on every other
+ * gesture group within the widget, and every gesture on parent widgets
+ * in the propagation chain.
+ * - Emitting [signal@Gtk.Gesture::cancel] on every gesture in widgets
+ * underneath in the propagation chain.
* - Stopping event propagation after the gesture group handles the event.
*
- * Note: if a sequence is set early to #GTK_EVENT_SEQUENCE_CLAIMED on
- * #GDK_TOUCH_BEGIN/#GDK_BUTTON_PRESS (so those events are captured before
- * reaching the event widget, this implies #GTK_PHASE_CAPTURE), one similar
- * event will emulated if the sequence changes to #GTK_EVENT_SEQUENCE_DENIED.
+ * Note: if a sequence is set early to %GTK_EVENT_SEQUENCE_CLAIMED on
+ * %GDK_TOUCH_BEGIN/%GDK_BUTTON_PRESS (so those events are captured before
+ * reaching the event widget, this implies %GTK_PHASE_CAPTURE), one similar
+ * event will emulated if the sequence changes to %GTK_EVENT_SEQUENCE_DENIED.
* This way event coherence is preserved before event propagation is unstopped
* again.
*
- * Sequence states can't be changed freely, see gtk_gesture_set_sequence_state()
- * to know about the possible lifetimes of a #GdkEventSequence.
+ * Sequence states can't be changed freely.
+ * See [method@Gtk.Gesture.set_sequence_state] to know about the possible

*
* ## Touchpad gestures
*
- * On the platforms that support it, #GtkGesture will handle transparently
- * touchpad gesture events. The only precautions users of #GtkGesture should do
- * to enable this support are:
- * - Enabling %GDK_TOUCHPAD_GESTURE_MASK on their #GdkSurfaces
+ * On the platforms that support it, `GtkGesture` will handle transparently
+ * touchpad gesture events. The only precautions users of `GtkGesture` should
+ * do to enable this support are:
+ *
* - If the gesture has %GTK_PHASE_NONE, ensuring events of type
- * %GDK_TOUCHPAD_SWIPE and %GDK_TOUCHPAD_PINCH are handled by the #GtkGesture
+ * %GDK_TOUCHPAD_SWIPE and %GDK_TOUCHPAD_PINCH are handled by the `GtkGesture`
