/// [`Gesture`][crate::Gesture] 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 [`None`] [`gdk::EventSequence`][crate::gdk::EventSequence] value for these).
///
/// The number of touches that a [`Gesture`][crate::Gesture] need to be recognized is controlled
/// by the `property::Gesture::n-points` property, if a gesture is keeping track of less
/// or more than that number of sequences, it won't check wether the gesture
/// is recognized.
///
/// As soon as the gesture has the expected number of touches, the gesture will
/// run the `signal::Gesture::check` signal regularly on input events until the gesture
/// is recognized, the criteria to consider a gesture as "recognized" is left to
/// [`Gesture`][crate::Gesture] subclasses.
///
/// A recognized gesture will then emit the following signals:
/// - `signal::Gesture::begin` when the gesture is recognized.
/// - A number of `signal::Gesture::update`, whenever an input event is processed.
/// - `signal::Gesture::end` when the gesture is no longer recognized.
///
/// ## Event propagation
///
/// In order to receive events, a gesture needs to either set a propagation phase
/// through [`EventControllerExt::set_propagation_phase()`][crate::prelude::EventControllerExt::set_propagation_phase()], or feed those manually
/// through [`EventControllerExt::handle_event()`][crate::prelude::EventControllerExt::handle_event()].
///
/// 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.
///
/// After the capture phase, GTK+ emits the traditional `signal::Widget::button-press-event`,
/// `signal::Widget::button-release-event`, `signal::Widget::touch-event`, etc signals. Gestures
/// with the [`PropagationPhase::Target`][crate::PropagationPhase::Target] phase are fed events from the default `signal::Widget::event`
/// handlers.
///
/// 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 [`GestureExt::group_with()`][crate::prelude::GestureExt::group_with()],
/// grouped gestures synchronize the state of sequences, so calling
/// [`GestureExt::set_sequence_state()`][crate::prelude::GestureExt::set_sequence_state()] on one will effectively propagate
/// the state throughout the group.
///
/// By default, all sequences start out in the [`EventSequenceState::None`][crate::EventSequenceState::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 [`EventSequenceState::Denied`][crate::EventSequenceState::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 [`EventSequenceState::Claimed`][crate::EventSequenceState::Claimed] state, the gesture
/// group will grab all interaction on the sequence, by:
/// - Setting the same sequence to [`EventSequenceState::Denied`][crate::EventSequenceState::Denied] on every other gesture
/// group within the widget, and every gesture on parent widgets in the propagation
/// chain.
/// - calling `signal::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 [`EventSequenceState::Claimed`][crate::EventSequenceState::Claimed] on
/// `GDK_TOUCH_BEGIN`/`GDK_BUTTON_PRESS` (so those events are captured before
/// reaching the event widget, this implies [`PropagationPhase::Capture`][crate::PropagationPhase::Capture]), one similar
/// event will emulated if the sequence changes to [`EventSequenceState::Denied`][crate::EventSequenceState::Denied].
/// This way event coherence is preserved before event propagation is unstopped
/// again.
///
/// Sequence states can't be changed freely, see [`GestureExt::set_sequence_state()`][crate::prelude::GestureExt::set_sequence_state()]
/// to know about the possible lifetimes of a [`gdk::EventSequence`][crate::gdk::EventSequence].
///
/// ## Touchpad gestures
///
/// On the platforms that support it, [`Gesture`][crate::Gesture] will handle transparently
/// touchpad gesture events. The only precautions users of [`Gesture`][crate::Gesture] should do
/// to enable this support are:
/// - Enabling [`gdk::EventMask::TOUCHPAD_GESTURE_MASK`][crate::gdk::EventMask::TOUCHPAD_GESTURE_MASK] on their `GdkWindows`
/// - If the gesture has [`PropagationPhase::None`][crate::PropagationPhase::None], ensuring events of type
/// `GDK_TOUCHPAD_SWIPE` and `GDK_TOUCHPAD_PINCH` are handled by the [`Gesture`][crate::Gesture]
///
/// This is an Abstract Base Class, you cannot instantiate it.
///
