<HTML><BODY>Hi. I'm working on a window manager and I got a few questions concerning WM_CLASS property. The questions are: 1. What is WM_CLASS's purpose? I thought it's to find X resources set by xrdb but Xrm* functions doesn't seem to depend on it. Is there any specific purpose, or does WM_CLASS have no specific purpose and just stores the info that other apps/users decide on how to use it? 2. Are there rules that an application should follow when setting res_name and res_class? For example, let's suppose I have a window manager somebox that has taskbar, dock, menus for starting applications/switching workspaces and configuration dialogs. What should be res_name/res_class for each of them? Accordng to manpage, res_name should be the application name and res_class should be the application class. So all the windows listed above should have the same res_name="somebox", res_class="WindowManager". But many apps I've seen don't seem to follow this logic. What's the proper way to set WM_CLASS for the windows? Is this the appropriate mailing list to ask this question, or should I write somewhere else? -- pv </BODY></HTML>
