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