[Bf-committers] XIM improvement (non-latin support + connection recovery)

[Tamito KAJIYAMA]

Irie-san,

Thank you for the information.  With a Ubuntu 10.04 installation on a real
machine, the XIM improvement patch version 2 works as expected.  For instance
object names with Japanese characters can be entered and displayed properly.
As you mentioned in the patch description, Japanese characters in the text
editor are displayed as blank rectangles.  So, everything seems okay now.

I will remain at your disposal if you need further testing of XIM patch updates.

Regards,

Hi Kajiyama-san,

1. I confirmed the same error on Ubuntu 11.10 + VirtualBox 4.1.8, but
I also got this error without applying my patch when quitting Blender
by Control+Q + ENTER.  Maybe this error happens if XIM server attempts
to send the reply to already deleted window.  I think it's no problem
because the error handler ApplicationErrorHandler() in
GHOST_WindowX11.cpp simply display the message.

2. I'm using Ubuntu 11.10 amd64 on a real machine.  In my test
environment, the international font is properly displayed with no
specific font setting except in the text editor.  I guess the
unreadable blank text in VirtualBox is due to the graphic driver (not
for your font setting).

Currently Blender's text editor uses a hard-coded monospace font
defined in source/blender/editors/datafiles/bmonofont.ttf.c.  This
font doesn't have the Japanese glyphs and cannot be changed to another
one by any settings, unfortunately.  I tried making another patch that
uses international monospace font, but showing the cursor and the
word-wrapping didn't work correctly because the text editor doesn't
consider wide-characters at all.  Probably the text editor needs
drastic changes to use international font.

Anyway, thanks for the testing!
