- gtkGesture
GtkGesture* gtkGesture;
- getGestureStruct
GtkGesture* getGestureStruct(bool transferOwnership)
- getStruct
void* getStruct()
the main Gtk struct as a void*
- setStruct
void setStruct(GObject* obj)
Undocumented in source. Be warned that the author may not have intended to support it.
- getType
GType getType()
- getBoundingBox
bool getBoundingBox(GdkRectangle rect)
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.
- getBoundingBoxCenter
bool getBoundingBoxCenter(double x, double y)
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.
- getDevice
Device getDevice()
Returns the master #GdkDevice that is currently operating
on @gesture, or %NULL if the gesture is not being interacted.
- getGroup
ListG getGroup()
Returns all gestures in the group of @gesture
- getLastEvent
Event getLastEvent(GdkEventSequence* sequence)
Returns the last event that was processed for @sequence.
- getLastUpdatedSequence
GdkEventSequence* getLastUpdatedSequence()
Returns the #GdkEventSequence that was last updated on @gesture.
- getPoint
bool getPoint(GdkEventSequence* sequence, double x, double y)
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.
- getSequenceState
GtkEventSequenceState getSequenceState(GdkEventSequence* sequence)
Returns the @sequence state, as seen by @gesture.
- getSequences
ListG getSequences()
Returns the list of #GdkEventSequences currently being interpreted
by @gesture.
- getWindow
Window getWindow()
Returns the user-defined window that receives the events
handled by @gesture. See gtk_gesture_set_window() for more
information.
- group
void group(Gesture gesture)
Adds @gesture to the same group than @group_gesture. Gestures
are by default isolated in their own groups.
- handlesSequence
bool handlesSequence(GdkEventSequence* sequence)
Returns %TRUE if @gesture is currently handling events corresponding to
@sequence.
- isActive
bool isActive()
Returns %TRUE if the gesture is currently active.
A gesture is active meanwhile there are touch sequences
interacting with it.
- isGroupedWith
bool isGroupedWith(Gesture other)
Returns %TRUE if both gestures pertain to the same group.
- isRecognized
bool isRecognized()
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.
- setSequenceState
bool setSequenceState(GdkEventSequence* sequence, GtkEventSequenceState state)
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:
- setState
bool setState(GtkEventSequenceState state)
Sets the state of all sequences that @gesture is currently
interacting with. See gtk_gesture_set_sequence_state()
for more details on sequence states.
- setWindow
void setWindow(Window window)
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().
- ungroup
void ungroup()
Separates @gesture into an isolated group.

on @gesture (manually, due to grabs...), or the individual @sequence
was claimed by parent widgets' controllers (see gtk_gesture_set_sequence_state()).
