Function
GdkWindowInvalidateHandlerFunc
Description [src]
Whenever some area of the window is invalidated (directly in the
window or in a child window) this gets called with region
in
the coordinate space of window
. You can use region
to just
keep track of the dirty region, or you can actually change
region
in case you are doing display tricks like showing
a child in multiple places.
