Re: focus problem

I got a long description from an X expert of the correct way to handle
focus detection in X.  I was going to implement it, but it was so
complex that I never got to it.  It would be good for someone to
implement it.  I will search for it when someone volunteers.

focus problem

This bug report will be sent to the Free Software Foundation,
not to your local site managers!
Please write in English, because the Emacs maintainers do not have
translators to read other languages for them.

Your bug report will be posted to the bug-gnu-emacs@gnu.org mailing list,
and to the gnu.emacs.bug news group.

In GNU Emacs 21.2.1 (i686-pc-linux-gnu, X toolkit)
 of 2002-04-08 on gupu.complang.tuwien.ac.at
configured using `configure  --without-toolkit-scroll-bars --prefix /usr'
Important settings:

Please describe exactly what actions triggered the bug
and the precise symptoms of the bug:


Start emacs under X in a failsafe session, i.e. a session without any
windowmanager - well, rather frame-manager ;-).  Move the mouse into
the emacs-frame.  The cursor remains hollow.  Only when invoking a
window-manager (e.g. twm) the cursor becomes filled.

This is particularily distracting if several emacs-windows are used,
since they contain all a hollow cursor (only the status-bar remains a
hint to tell where the current place is).

Previous emacs versions (20.7.2, 21.1.1) behaved as expected: When the
mouse moved into the emacs-frame, the cursor became filled even
without a windowmanager.  Traditional X-applications (e.g. xterm) also
behave this way.

I considered x-autoselect-window focus-follows-mouse
cursor-in-non-selected-windows mentioned in the NEWS but to no avail.

--

Using no window-manager today seems rather anacronistic, but these are
actual uses where the problem showed up:

a) Using emacs remotely via Cygwin/XFree from an MS Windows machine.

b) Using emacs remotely with older and slow X-Terminals

(I reported this on Fri Mar 15 15:23:04 2002 to
emacs-pretest-bug@gnu.org for 21.2.50.1 already, no reaction so far.
The last modification in 21.2.1 appears to have happened on Mar 16
12:38)

If no one has volunteered, I can look at it.  Can you mail the description?

Thanks,
