Re: How to properly use XGrabKey to get a program hotkey
This will only work if the window manager or the window with focus doesn't already grab the same keys. Does the example work without a window manager running? Thanks for the reply, but I believe libX will generate an error if the keys are already grabbed. In this case there is no error generated. Anyway, I discovered the problem. I was using the ControlMask modifier, and the numlock was down on my keyboard. Evidently numlock counts as a modifier. *doh*. The example works fine now. ___ xorg@lists.freedesktop.org: X.Org support Archives: http://lists.freedesktop.org/archives/xorg Info: http://lists.freedesktop.org/mailman/listinfo/xorg Your subscription address: arch...@mail-archive.com

My goal is to have a program that sleeps in the background but can be activated by the user via some hotkey. From digging around the Xlib Is this program running as the normal user or is this some privileged service (say switch to another user)? Normal user. I don't think there's any need to perform privileged actions for this application. ___ xorg@lists.freedesktop.org: X.Org support Archives: http://lists.freedesktop.org/archives/xorg Info: http://lists.freedesktop.org/mailman/listinfo/xorg Your subscription address: arch...@mail-archive.com

From digging around the Xlib manual and the Xlib O'reilly manual, I gather that the correct way to to this is with XGrabKey. However my understanding of the process is incorrect as a simple proof of concept does not work. My understanding is that if I call XGrabKey with the root window as the grab_window, and owner_events false, then whenever my hotkey is pressed the event will be sent *only* to the root window. If I then select KeyPress events from the root window, and then listen for X events, I should get a key press event when the hotkey is pressed. I've pasted a minimal example below. What I expect is that when the program is run, regardless of what window has focus, if Ctrl+Shift+K is pressed, my program should output Hot key pressed! in the console, and then terminate. Furthermore, it is my understanding that if the XGrabKey fails, the default error handler will display a message, and since it does not I am assuming that the call succeeds. Obviously, my understanding is flawed somehow. Can anyone point me in the right direction? This will only work if the window manager or the window with focus doesn't already grab the same keys.
