Artificial Italic doesnt’t work in Qt3/Qt4/KDE3/KDE4.

Comment 1 Mike Fabian 2008-03-26 17:34:04 UTC

Artificial bold doesn’t work in qtconfig, neither of Qt4 nor of Qt3
and it doesn’t work either in the KDE3 control centre (kcontrol).
Only regular and italic are selectable.

Of course CJK fonts like FZSongTi usually have only regular, but italic and
bold can be “faked” by freetype2 as one can easily verify by using:

   xfd -fa "FzSongTi:size=12:weight=200"

And bold-italic:

   xfd -fa "FzSongTi:size=12:weight=200:slant=100"

Therefore I don’t understand either why Qt doesn’t allow bold here.

In GTK2 applications, for example gedit, this works.

I found this patch from 
http://www.kde-apps.org/content/show.php/FakeBold+Font+patches+for+QT+4.3.x?content=64029
I've modified it for qt4.4, and build it in Build Service
https://build.opensuse.org/package/show?package=libqt4&project=home%3Aswyear
I've test for days, seem works fine.

Comment 5 Dirk Mueller 2008-04-02 09:48:36 UTC

I'll add the patches to the next qt4 update round. qt3 part is wontfix for now, unless somebody adapts the patch. 

Thanks for finding them on the net :)

Comment 6 Dirk Mueller 2008-04-02 13:49:59 UTC

submitted for factory

Comment 7 Mike Fabian 2008-04-03 15:31:36 UTC

I’ve verified that it works in Factory now. Thank you very much!

Comment 8 Dirk Mueller 2008-04-10 13:26:18 UTC

causes rendering regressions, as those fake-embolded glyphs are wider, but qt doesn't know about it, so glyphs are cut off

visible quite clearly in konsole, it became completely unusable with the patch. I Have to back it  out for now, sorry.

Comment 9 Dirk Mueller 2008-04-21 12:45:55 UTC

pinged trolltech about it.

Comment 10 Dirk Mueller 2008-05-19 08:34:11 UTC

Any status on this it's been almost a year since the last comment?

Comment 13 Dirk Mueller 2010-04-26 08:59:23 UTC

no time to work on this anymore, please file a bugreport upstream (now that there is a public issue tracker). Thanks!
