From the Frequently Asked Questions posting: ---------------------------------------------------------------------- Subject: 74) Why doesn't my program get the keystrokes I select for? The window manager controls how the input focus is transferred from one window to another. In order to get keystrokes, your program must ask the window manager for the input focus. To do this, you must set up what are called "hints" for the window manager. If your applications is Xlib-based, you can use something like the following: XWMHints wmhints; ... wmhints.flags = InputHint; wmhints.input = True; XSetWMHints(dpy, window, &hints) If your application is based on the Xt Intrinsics, you can set the XtNinput resource to be True (as you probably want to in any case); if you don't have source, you can start up the application with the resource '*input:True'. Certain window managers, notably dxwm and olwm, are very picky about having this done. If you are using Sun's OpenWindows olwm, you can also add this resource to your defaults file to use clients that aren't ICCCM-compliant.
