Description Usage Arguments Details Author(s)

Request more motion notifies if event is a motion notify hint event. This function should be used instead of gdkWindowGetPointer to request further motion notifies, because it also works for extension events where motion notifies are provided for devices other than the core pointer. Coordinate extraction, processing and requesting more motion events from a GDK_MOTION_NOTIFY event usually works like this:

1	gdkEventRequestMotions(event)

event

a valid GdkEvent

# motion event handler
{
  x <- motion_event$x
  y <- motion_event$y
  # handle (x,y) motion here
  motion_event$request_motions() # handles is_hint events
}
