GestureSwipeSignalName

Emitted when the gesture is recognized.

This means the number of touch sequences matches [propertyGtk.Gesture:n-points].

Note: These conditions may also happen when an extra touch (eg. a third touch on a 2-touches gesture) is lifted, in that situation sequence won’t pertain to the current set of active touches, so don’t rely on this being true.

Emitted whenever a sequence is cancelled.

This usually happens on active touches when [methodGtk.EventController.reset] is called on gesture (manually, due to grabs…), or the individual sequence was claimed by parent widgets’ controllers (see [methodGtk.Gesture.set_sequence_state]).

gesture must forget everything about sequence as in response to this signal.

Emitted when gesture either stopped recognizing the event sequences as something to be handled, or the number of touch sequences became higher or lower than [propertyGtk.Gesture:n-points].

Note: sequence might not pertain to the group of sequences that were previously triggering recognition on gesture (ie. a just pressed touch sequence that exceeds [propertyGtk.Gesture:n-points]). This situation may be detected by checking through [methodGtk.Gesture.handles_sequence].

The notify signal is emitted on an object when one of its properties has its value set through g_object_set_property(), g_object_set(), et al.

Note that getting this signal doesn’t itself guarantee that the value of the property has actually changed. When it is emitted is determined by the derived GObject class. If the implementor did not create the property with G_PARAM_EXPLICIT_NOTIFY, then any call to g_object_set_property() results in notify being emitted, even if the new value is the same as the old. If they did pass G_PARAM_EXPLICIT_NOTIFY, then this signal is emitted only when they explicitly call g_object_notify() or g_object_notify_by_pspec(), and common practice is to do that only when the value has actually changed.

This signal is typically used to obtain change notification for a single property, by specifying the property name as a detail in the g_signal_connect() call, like this:

(C Language Example):

g_signal_connect (text_view->buffer, "notify::paste-target-list",
                  G_CALLBACK (gtk_text_view_target_list_notify),
                  text_view)

It is important to note that you must use canonical parameter names as detail strings for the notify signal.

Emitted whenever a sequence state changes.

See [methodGtk.Gesture.set_sequence_state] to know more about the expectable sequence lifetimes.

Emitted when the recognized gesture is finished.

Velocity and direction are a product of previously recorded events.

Emitted whenever an event is handled while the gesture is recognized.

sequence is guaranteed to pertain to the set of active touches.

Mouse button number to listen to, or 0 to listen for any button.

Whether the gesture is exclusive.

Exclusive gestures only listen to pointer and pointer emulated events.

The number of touch points that trigger recognition on this gesture.

The name for this controller, typically used for debugging purposes.

The limit for which events this controller will handle.

The propagation phase at which this controller will handle events.

Whether the gesture handles only touch events.

The widget receiving the GdkEvents that the controller will handle.
