gdk:window-freeze-updates (window)

window -- a gdk:window object

Temporarily freezes a window such that it will not receive expose events. The window will begin receiving expose events again when the gdk:window-thaw-updates function is called. If the gdk:window-freeze-updates function has been called more than once, the gdk:window-thaw-updates function must be called an equal number of times to begin processing exposes.
