If it is not, you may still get the drawings on the screen by calling XFlush(), but what you should do is probably one of: o use XtAddEventHandler to handle Expose events o add a XtActionProc to handle Expose events and define a translation table like: <Expose>: my-expose-handler() o Add a subclass of the core widget and set the XtExposeProc field o Draw to a pixmap and set the backgroundPixmap resource Just some options from what I could understand from the small code sample.
