Window manager: gwm
What were you trying to do?
Use the sort-of-latest, allegedly-greatest, web browser mozilla.
What's wrong:
mozilla ignores keyboard input.
After some investigation I determined that mozilla requires
that XSetInputFocus be used with one of its top level windows
as argument. I (via my window manager) have focus set to
PointerRoot, meaning keyboard input goes to the window where
the cursor is or the nearest ancestor window that wants input.
The setting of input focus is supposed to be invisble to clients.
The only way for a client to tell which policy is in use is to
call XGetInputFocus.
As long as the cursor is within the mozilla window, mozilla
receives exactly the same events whichever value is used for
the focus window. However, if focus is set to PointerRoot then
mozilla IGNORES the keyboard events. They are received and go
into the complicated input processing code, which decides they
are not interesting.
So far I have not found an obvious explanation for this behavior,
either in the source code or by speculating "what were they thinking?"
As far as I can tell my window manager (gwm) is following the
ICCCM standard. I do not find the common window manager behavior
where focus is actively moved every time the mouse moved to be
an acceptable substitute for the X default input model.
This behavior happens with the release version
Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.0.0) Gecko/20020529, build 2002052918
and with /mit/mozilla/.../mozbeta
Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.3a) Gecko/20021213, build 2002121308
What should have happened:
mozilla should not care what the user-specified root focus window is
Please describe any relevant documentation references:
XSetInputFocus(3X11)
