  1. gestureHandlesSequence :: (HasCallStack, MonadIO m, IsGesture a) => a -> Maybe EventSequence -> m Bool

    gi-gtk3 GI.Gtk.Objects.Gesture

    Returns True if gesture is currently handling events corresponding to sequence. Since: 3.14

  2. gestureSetSequenceState :: (HasCallStack, MonadIO m, IsGesture a) => a -> EventSequence -> EventSequenceState -> m Bool

    gi-gtk3 GI.Gtk.Objects.Gesture

    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:

    • None
    • None → Denied
    • None → Claimed
    • None → Claimed → Denied
    Note: Due to event handling ordering, it may be unsafe to set the state on another gesture within a Gesture::begin signal handler, as the callback might be executed before the other gesture knows about the sequence. A safe way to perform this could be: 
    static void
first_gesture_begin_cb (GtkGesture       *first_gesture,
GdkEventSequence *sequence,
gpointer          user_data)
{
gtk_gesture_set_sequence_state (first_gesture, sequence, GTK_EVENT_SEQUENCE_CLAIMED);
gtk_gesture_set_sequence_state (second_gesture, sequence, GTK_EVENT_SEQUENCE_DENIED);
}

static void
second_gesture_begin_cb (GtkGesture       *second_gesture,
GdkEventSequence *sequence,
gpointer          user_data)
{
if (gtk_gesture_get_sequence_state (first_gesture, sequence) == GTK_EVENT_SEQUENCE_CLAIMED)
gtk_gesture_set_sequence_state (second_gesture, sequence, GTK_EVENT_SEQUENCE_DENIED);
}
    If both gestures are in the same group, just set the state on the gesture emitting the event, the sequence will be already be initialized to the group's global state when the second gesture processes the event. Since: 3.14

  3. onGestureSequenceStateChanged :: (IsGesture a, MonadIO m) => a -> ((?self :: a) => GestureSequenceStateChangedCallback) -> m SignalHandlerId

    gi-gtk3 GI.Gtk.Objects.Gesture

    Connect a signal handler for the sequenceStateChanged signal, to be run before the default handler. When overloading is enabled, this is equivalent to 

    on gesture #sequenceStateChanged callback

  4. gestureSingleGetCurrentSequence :: (HasCallStack, MonadIO m, IsGestureSingle a) => a -> m (Maybe EventSequence)

    gi-gtk3 GI.Gtk.Objects.GestureSingle

    Returns the event sequence currently interacting with gesture. This is only meaningful if gestureIsActive returns True. Since: 3.14
