Bug in FOX related to composed characters and proposed patch

Hi there,

some weeks ago, I sent here a message where I described a bug related to
composed characters and XIM inputs. These characters are frequently used
for example in french (ex: â ô ), in german (to do the umlaut like in ü
ä ¶ etc.) and other languages.

For these characters to be correctly input in FOX application, the FOX
library must be compiled with the --with-xim configure option.

In FOX 1.6.36 and 1.7.19, compiled with the --with-xim option, entering
composed characters *only* works when the mouse pointer (caution : the
mouse pointer, not the input cursor) lies within the text field that has
the focus. Otherwise, if the mouse pointer is elsewhere in the window,
it is not possible to input characters like â ä ü û¶, etc. This can be
easily checked with adie : write a text and move the mouse pointer
outside the adie window. Then entering composed characters don't work
anymore.

After some (deep) investigations, I finally found where the problem is
and fixed the bug. I attached here a patch for the FXApp.cpp class of
FOX 1.6.36.

I succesfully tested this patch on the following Linux systems : Debian
Lenny (stable), latest Ubuntu, Mandriva 2009 but I didn't test it on
Windows.

Hope this post could help to definitely fix this annoying bug.

Best regards,
Roland
