Re: Help with partial line needed (was: Bad resizing upon detaching/reattaching GTK toolbar)

There is definitly some bug in fluxbox, it sends the most crazy
configure notify events to Emacs when the tool bar is detached. It
usually sends three, two correct ones and one that is off by about 5
pixels. It is those missing 5 pixels that shrinks the window (i.e.
Emacs rounds it to an even line). There should only be one configure
Emacs is special in the way it handles (or rather the GTK version)
detaching and attaching of the tool bar. It tries to keep the same
lines as before, thus the resizing and the configure notify events.
I see that other applications instead keeps the total pixel size, so
then no configure notify is sent (the frame size is kept). I can change
to that behaviour, but since the tool bar height may not be a multiple
of the line height (as it is in other Emacs ports), there will most
probably be a partial line. And that partial line is the minibuffer.
It would be better if that partial line was in a non-minibuffer. Does
anybody know how to achive that (I just call change_frame_size)?
There are another race condition involving configure notify and tool bar
attach/detach, but they happen very seldom, and usually ends up growing
the Emacs frame rather than shrink it. The fluxbox behaviour is not
changed by fixing that race condition. I haven't checked in the fix for
the race condition. If there is a way to force the partial line to a
non-minibuffer I think I'll go with that solution instead.
Sorry I couldn't help.

Please write in English if possible, because the Emacs maintainers
usually do not have translators to read other languages for them.
Your bug report will be posted to the address@hidden mailing list.
Please describe exactly what actions triggered the bug
and the precise symptoms of the bug:
When one detaches and reattaches the toolbar by dragging on its
handle, each time the total size of the Emacs window shrinks. This is
particularly noisome since it is not easy to reattach the toolbar
without the state attached/detached flickering a few times, and each
time one line of the window is gone.
I can not reproduce this, what window manager are you running?
Do you get the same behaviour if you disable and enable
First I get a backtrace. Sigh.
Debugger entered--Lisp error: (wrong-type-argument keymapp nil)
signal(wrong-type-argument (keymapp nil))
define-key-after(nil [customize] (menu-item "customize" customize :image (image :type xpm :file

tool-bar-add-item("preferences" customize customize :help "Edit preferences
Then the frame gets oversized (namely, the text window size does not
shrink to accommodate the toolbar size, and consequently the
minibuffer gets off-screen). If I disable the toolbar again, the
frame shrinks to normal size again, as the window size stays the same.
However, this first toggling is "neutral" only because of the back
trace, apparently (I have debug-on-error set to t).
The next time I call tool-bar-mode (no backtrace this time), the
window-size _adapts_ to the reduced space. Disabling tool-bar-mode
again, the window does _not_ adapt to the additional space again.
After that, enabling the toolbar makes the size adapt, so the frame
size stays more or less the same while the window size shrinks, and
disabling the toolbar lets the window size stay the same, thus causing
the frame to shrink.
The same happens when detaching and reattaching the toolbar: detach
the toolbar, and the window does not grow in spite of the additional
space, attach it again, and the window shrinks.
Maybe this is an effect of the combination of my line height and the
size of the toolbar? I use 10x20 as my normal font, and the startup
geometry is 80x35.
My X resources contain Emacs.toolBar: 0, so I don't have a toolbar on
