> Maybe I don't understand what the goal is here. The goal is to get notified by Gdk when a window will not have to draw itself (e.g. is hidden/invisible or whatever). I played a bit with the double-buffer implementation and to keep a single pixmap for the top-level window instead of creating/destroying a new pixmap for each paint per window. However now I am searching for a way to release this buffer if I know for sure that frequent re-paints are unlikely (-> e.g. the window is hidden). > If all you want is to know when one of the events in the Subject line > happens, then the simplest platform independent low-level way to do it > is the gdk_window_set_filter. Sorry I thought GdkXEvents are platform depandant. My fault, sorry :-/ ... the X confused me ;) I'll have a look there, thanks a lot! > My original point was that this information is in the GdkWindow API > documentation and locating it wasn't hard, even if you know little about > GTK+. I understand your rant, and I already studying GTKs reference frequently hopin to find the bits I am searching for. But its like double-buffering, the whole painting-process was explained in another document (thanks a lot, this really helps!) someone on the list told me. I found all the gtk hide/show signals but howto do it in Gdk -> then it becoms a bit dark for an gtk-unexperienced programmer. Maybe I would need hours/days searching and trying out for finding a suboptimal solution, which could be answered in one minute on the list. lg Clemens _______________________________________________ gtk-list@xxxxxxxxx http://mail.gnome.org/mailman/listinfo/gtk-list
