But I suspect this is not what you want... and no - there is no reliable way of getting a window id from some app you ran - the window ID is runtime assigned and can be anything. An app can open multiple windows (and often creates invisible windows you never see and sub windows etc. A large number of apps will set a _NET_WM_PID property on the window with the PID of the process that created the window - but not all. xterm does do this. Apps may set the WM_COMMAND property with the command that launched them (and any arguments). WM_CLASS may provide some hints as to the app that owns the window. you might have to follow the breadcrumbs and look at the window id referenced by WM_CLIENT_LEADER to get some of these properties. -- ------------- Codito, ergo sum - "I code, therefore I am" -------------- Carsten Haitzler - <a href="mailto:raster@rasterman.com" target="_blank">raster@rasterman.com</a> </blockquote></div>
