void gtk_gesture_group ( GtkGesture* group_gesture, GtkGesture* gesture )
gesture to the same group than
are by default isolated in their own groups.
When gestures are grouped, the state of
is kept in sync for all of those, so calling gtk_gesture_set_sequence_state(),
on one will transfer the same value to the others.
Groups also perform an “implicit grabbing” of sequences, if a
GdkEventSequence state is set to #GTK_EVENT_SEQUENCE_CLAIMED on one group,
every other gesture group attached to the same
GtkWidget will switch the
state for that sequence to #GTK_EVENT_SEQUENCE_DENIED.
