I written an application using Xlib that needs both KeyPress and
ButtonPress events. The program works correctly when I'm running twm but
whenever I try to run it under OLWM, it never gets the input focus. (I
do get the button events though.) Does anyone have any ideas of what I'm
doing wrong?
Configurations: Sun3/60s and 3/80s running SunOS4.0.3. Twm is running
under MIT X11R4.11. We've tried OpenWindows 2.0 Beta and MIT X11R4.11
using OpenWindows OLWM.

In short, your application is not asking for input; twm is willing to give it to you anyway, whereas OLWM is not. > (I do get the button events though.) Pointer events, such as ButtonPress events, always go where the pointer is[%]; there is no "please give me / don't give me pointer events" window manager hint. Look up XSetWMProperties in the R4 Xlib documentation; that's what you need to call. (The crucial thing is the wm_hints.input bit, which should be set to True. Of course, you'll also need to add InputHint to the wm_hints.flags field.) [%] Grabs complicate things; they can cause events to be generated relative to windows that have no relation to the windows they would normally be generated relative to. But this is true of keyboard and pointer events both, so it has no relevance to my point above. der Mouse old: mcgill-vision!mouse new: mouse@larry.mcrcim.mcgill.edu
