I want to call a function whenever I new window appears and another function when a window is closed. For instance when calling xcalc from a commandline.
So I wonder how this could be achieved without polling. I'm happily using fvwm for quite a long time, and there was always some way to do this or that. Anyway I feel this is a basic feature of a window manager, but couldn't find anything like WindowOpenedCommand WindowClosingCommand Any idea is deeply appreciated. Thanks. Uli.
