Class
ClutterTapAction
Description [src]
class Clutter.TapAction : Clutter.GestureAction
{
/* No available fields */
}
Action for tap gestures
ClutterTapAction
is a sub-class of ClutterGestureAction
that implements
the logic for recognizing mouse clicks and touch tap gestures.
The simplest usage of ClutterTapAction
consists in adding it to
a ClutterActor
, setting it as reactive and connecting a
callback for the ClutterTapAction::tap
signal, along the lines of the
following code:
clutter_actor_add_action (actor, clutter_tap_action_new ());
clutter_actor_set_reactive (actor, TRUE);
g_signal_connect (action, "tap", G_CALLBACK (on_tap_callback), NULL);
Instance methods

clutter_gesture_action_cancel
Cancel a ClutterGestureAction
before it begins.
clutter_gesture_action_get_device
Retrieves the ClutterInputDevice
of a touch point.
clutter_gesture_action_get_last_event
Retrieves a reference to the last ClutterEvent
for a touch point. Call
clutter_event_copy()
if you need to store the reference somewhere.
clutter_gesture_action_get_motion_coords

clutter_gesture_action_get_n_current_points
Retrieves the number of points currently active.
clutter_gesture_action_get_n_touch_points
Retrieves the number of requested points to trigger the gesture.
clutter_gesture_action_get_press_coords
Retrieves the coordinates, in stage space, of the press event that started the dragging for a specific touch point.
clutter_gesture_action_get_release_coords
Retrieves the coordinates, in stage space, where the touch point was last released.
clutter_gesture_action_get_sequence
Retrieves the ClutterEventSequence
of a touch point.
clutter_gesture_action_get_threshold_trigger_distance
Retrieves the threshold trigger distance of the gesture action
,
as set using clutter_gesture_action_set_threshold_trigger_distance()
.
clutter_gesture_action_get_threshold_trigger_edge
Retrieves the edge trigger of the gesture action
, as set using
clutter_gesture_action_set_threshold_trigger_edge()
.
clutter_gesture_action_get_velocity
Retrieves the velocity, in stage pixels per millisecond, of the latest motion event during the dragging.
clutter_gesture_action_set_n_touch_points
Sets the number of points needed to trigger the gesture.
clutter_gesture_action_set_threshold_trigger_distance
Sets the threshold trigger distance for the gesture drag threshold, if any.
clutter_gesture_action_set_threshold_trigger_edge
Sets the edge trigger for the gesture drag threshold, if any.

Signals
Signals inherited from ClutterGestureAction (4)
ClutterGestureAction::gesture-begin
The signal is emitted when the ClutterActor
to which
a ClutterGestureAction
has been applied starts receiving a gesture.
ClutterGestureAction::gesture-cancel
The signal is emitted when the ongoing gesture gets
cancelled from the ClutterGestureAction::gesture-progress
signal handler.
ClutterGestureAction::gesture-end
The signal is emitted at the end of the gesture gesture, when the pointer’s button is released.
ClutterGestureAction::gesture-progress
The signal is emitted for each motion event after
the ClutterGestureAction::gesture-begin
signal has been emitted.
Signals inherited from GObject (1)
GObject::notify
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.
