Description

GtkGestureLongPress is a GtkGesture implementation able to recognize long presses, triggering the “pressed” after the timeout is exceeded.

If the touchpoint is lifted before the timeout passes, or if it drifts too far of the initial press point, the “cancelled” signal will be emitted.

Returns a newly created GtkGesture that recognizes long presses.
