Class
ClutterPanGesture
Description [src]
final class Clutter.PanGesture : Clutter.Gesture
{
/* No available fields */
}A ClutterGesture subclass for recognizing pan gestures.
Instance methods
clutter_pan_gesture_get_accumulated_delta
Retrieves the accumulated delta from all events (ie. the total delta that the
pan has been moved) as accumulated_delta_out.
clutter_pan_gesture_get_begin_centroid_abs
Retrieves the begin centroid of self in absolute coordinates.
clutter_pan_gesture_get_begin_threshold
Gets the movement threshold in pixels that begins the pan gesture.
clutter_pan_gesture_get_centroid_abs
Retrieves the current centroid of the points active on self in
absolute coordinates.
clutter_pan_gesture_get_delta
Retrieves the delta between the current ::pan-update signal emission and the
one before as delta_out.
clutter_pan_gesture_get_max_n_points
Gets the maximum number of points set by clutter_pan_gesture_set_max_n_points().
clutter_pan_gesture_get_min_n_points
Gets the minimum number of points set by clutter_pan_gesture_set_min_n_points().
clutter_pan_gesture_get_pan_axis
Retrieves the axis constraint set by clutter_pan_gesture_set_pan_axis().
clutter_pan_gesture_set_begin_threshold
Sets the movement threshold in pixels to begin the pan gesture.
clutter_pan_gesture_set_max_n_points
Sets the maximum number of points to use for the pan. Set to 0 to allow an unlimited number.
Methods inherited from ClutterGesture (14)
clutter_gesture_can_not_cancel
In case self and other_gesture are operating on the same points, calling
this function will make sure that self does not cancel other_gesture
when self moves to state RECOGNIZING.
clutter_gesture_cancel
Cancels the gesture by setting its state to CANCELLED.
clutter_gesture_get_n_points
Retrieves the number of active points the gesture currently has.
clutter_gesture_get_point_begin_coords
Retrieves the begin coordinates of the point with index point_index.
clutter_gesture_get_point_begin_coords_abs
clutter_gesture_get_point_coords
Retrieves the latest coordinates of the point with index point_index.
clutter_gesture_get_point_coords_abs
clutter_gesture_get_point_event
Retrieves the the latest event of the point with index point_index.
clutter_gesture_get_point_previous_coords
Retrieves the previous coordinates of the point with index point_index.
clutter_gesture_get_point_previous_coords_abs
clutter_gesture_get_points
Retrieves an array of the currently active points of the gesture, the array is ordered in the order the points were added in (newest to oldest).
clutter_gesture_get_state
Gets the current state of the gesture.
clutter_gesture_reset_state_machine
clutter_gesture_set_state
Sets the state of the gesture. This method is private to gesture implementations.
Methods inherited from ClutterAction (1)
Methods inherited from ClutterActorMeta (5)
clutter_actor_meta_get_actor
Retrieves a pointer to the ClutterActor that owns meta.
clutter_actor_meta_get_enabled
Retrieves whether meta is enabled.
clutter_actor_meta_get_name
Retrieves the name set using clutter_actor_meta_set_name().
clutter_actor_meta_set_enabled
Sets whether meta should be enabled or not.
clutter_actor_meta_set_name
Sets the name of meta.
Properties
Clutter.PanGesture:begin-threshold
The threshold in pixels that has to be panned for the gesture to start.
Clutter.PanGesture:max-n-points
The maximum number of points to use for the pan. Set to 0 to allow an unlimited number. Defaults to 0.
Clutter.PanGesture:min-n-points
The minimum number of points for the gesture to start, defaults to 1.
Properties inherited from ClutterGesture (1)
Properties inherited from ClutterActorMeta (3)
Clutter.ActorMeta:actor
The ClutterActor attached to the ClutterActorMeta instance.
Clutter.ActorMeta:enabled
Whether or not the ClutterActorMeta is enabled.
Clutter.ActorMeta:name
The unique name to access the ClutterActorMeta.
Signals
Clutter.PanGesture::pan-update
The ::pan-update signal is emitted when one or multiple points of the pan have changed.
Signals inherited from ClutterGesture (5)
ClutterGesture::cancel
The ::cancel signal is emitted when a continuous gesture got cancelled.
ClutterGesture::end
The ::end signal is emitted when a continuous gesture ends.
ClutterGesture::may-recognize
The ::may-recognize signal is emitted if the gesture might become active and move to RECOGNIZING. Its purpose is to allow the implementation or a user of a gesture to prohibit the gesture from starting when needed.
ClutterGesture::recognize
The ::recognize signal is emitted when the gesture recognizes.
ClutterGesture::should-handle-sequence
The ::should-handle-sequence signal is emitted when a sequence gets added
to the gesture. Return FALSE to make the gesture ignore the sequence of events.
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.
