Nice. That worked. FWIW, Tk never gave me the very outermost window as the parent of the tkinter.Tk instance. Here's the start of hierarchy: % xwininfo -tree xwininfo: Please select the window about which you would like information by clicking the mouse in that window. xwininfo: Window id: 0x5a0001f "Typing Watcher" Root window id: 0x7a2 (the root window) (has no name) Parent window id: 0xc73880 (has no name) 1 child: 0x5a0001e (has no name): () 178x126+0+0 +2+43 1 child: 0x5a00020 (has no name): () 178x126+0+0 +2+43 5 children: ... Tk thought 0x5a0001e was the top, but as you can see 0x5a0001f is the named window. Calling wmctrl using "Typing Watcher" as the target window did the trick.
