`GtkGestureLongPress` is a `GtkGesture` for long presses.
This gesture is also known as “Press and Hold”.
When the timeout is exceeded, the gesture is triggering the [[email protected]:GtkGestureLongPress:pressed]
signal.
If the touchpoint is lifted before the timeout passes, or if it drifts too far of the initial press point, the [
[email protected]:GtkGestureLongPress:cancelled] signal will be emitted.
How long the timeout is before the pressed signal gets emitted is
determined by the [[email protected]:gtk-long-press-time] setting. It can be modified by the [
[email protected]:delay-factor] property.
