GtkGestureZoom

If there are touch sequences being currently handled by gesture, this function returns TRUE and fills in rect with the bounding box containing all active touches. Otherwise, FALSE will be returned.

since: 3.14

If there are touch sequences being currently handled by gesture, this function returns TRUE and fills in x and y with the center of the bounding box containing all active touches. Otherwise, FALSE will be returned.

since: 3.14

Returns the master GdkDevice that is currently operating on gesture, or NULL if the gesture is not being interacted.

since: 3.14

Returns all gestures in the group of gesture.

since: 3.14

Returns the last event that was processed for sequence.

Returns the GdkEventSequence that was last updated on gesture.

since: 3.14

If sequence is currently being interpreted by gesture, this function returns TRUE and fills in x and y with the last coordinates stored for that event sequence. The coordinates are always relative to the widget allocation.

since: 3.14

Returns the sequence state, as seen by gesture.

since: 3.14

Returns the list of GdkEventSequences currently being interpreted by gesture.

since: 3.14

Returns the user-defined window that receives the events handled by gesture. See gtk_gesture_set_window() for more information.

since: 3.14

Adds gesture to the same group than group_gesture. Gestures are by default isolated in their own groups.

since: 3.14

Returns TRUE if gesture is currently handling events corresponding to sequence.

since: 3.14

Returns TRUE if the gesture is currently active. A gesture is active meanwhile there are touch sequences interacting with it.

since: 3.14

Returns TRUE if both gestures pertain to the same group.

since: 3.14

Returns TRUE if the gesture is currently recognized. A gesture is recognized if there are as many interacting touch sequences as required by gesture, and GtkGesture::check returned TRUE for the sequences being currently interpreted.

since: 3.14

Sets the state of sequence in gesture. Sequences start in state #GTK_EVENT_SEQUENCE_NONE, and whenever they change state, they can never go back to that state. Likewise, sequences in state #GTK_EVENT_SEQUENCE_DENIED cannot turn back to a not denied state. With these rules, the lifetime of an event sequence is constrained to the next four:.

since: 3.14

Sets the state of all sequences that gesture is currently interacting with. See gtk_gesture_set_sequence_state() for more details on sequence states.

since: 3.14

Sets a specific window to receive events about, so gesture will effectively handle only events targeting window, or a child of it. window must pertain to gtk_event_controller_get_widget().

since: 3.14

Separates gesture into an isolated group.

since: 3.14

Gets the propagation phase at which controller handles events.

since: 3.14

Returns the GtkWidget this controller relates to.

since: 3.14

Feeds an events into controller, so it can be interpreted and the controller actions triggered.

since: 3.14

Resets the controller to a clean state. Every interaction the controller did through GtkEventController::handle-event will be dropped at this point.

since: 3.14

Sets the propagation phase at which a controller handles events.
