Hi Forum,
during the X-mas holidays I had a bit of time and decided to upgrade my 2nd mashine to openSUSE 11.1 which ships with KDE4.1.3. Directly after that I added the KDE 4.2 dev. Repos and did an update to KDE4.2 (4.1.87) which went all well. Then I started with configuring the desktop and found some strange behaviour on some apps regarding Fonts. Especially YAST2 and Kaffeine (0.87) had micro fonts (maybe size 2) and all the gtk apps fonts were small (not that small) as well. The KDE Font settings didn’t show any effect. I spent hours with searching and trying to solve this and finally installed gnome-control-centre which started with microfonts again. After finding the appearance sections and setting font sizes for gtk apps to the level equal to the KDE Font settings everything worked well. I can understand this for the gtk apps but what I do not understand why also the Kaffeine and Yast fonts were ok after that exercise as I believe those apps are qt based and should be able to follow the KDE settings. I have almost 4 years experience now on Linux usage and configuring (not programming) and did a lot of tricky things already but I can understand the frustration of users new to Linux and KDE. The choice and freedom causes some really bad issues in terms of compatibility. Who would think istalling a configuration tool from Gnome (even i have chosen to use KDE) to set up fonts for KDE apps ?!

Maybe should mention that on the 2nd machine I use a 37" TV at 1080p resolution with Font size 24 now for dayly internet and emailing stuff.... Maybe on a normal 22" monitor with font size 10 I wouldnt have had any issue - who knows.

Nevertheless, I think KDE4 - even not yet home - is a very nice Desktop. It looks great, already feature rich and still not yet too resource hungry (works just fine on my old 2nd with 512MB RAM). But for my 1st machine I'd better stay with 3.5.10 for the next while.

I have no idea why using the GNOME settings panel would have had any effect upon YaST and Kaffeine, apart from the fact that you could be using the Gtk version of YaST, and that Kaffeine for 4.2 is still in heavy development.

Hi bcooksley, thats exactly what I was wondering about as well. I am using the Yast-qt package and kaffeine 0.8.7 and not the new alpha. I created a new user accout just to try. After login all fonts are at 10 which is the pre-setting and not readable in my configuration. Anyway, have set the fonts in KDE settings then to 26. To make sure all new config files are used, I loged off and in again and the screenshot here shows what happens....

Yast and Kaffeine keep the low font sizes while native qt4 apps are ok. I started gnome-appearance-properties from the console and set the fonts to 22 - thats almost equal to size 26 for qt apps. Kaffeine and Yast were just fine after this again. So its exactly re-producable for me. I will further check what configuration files have changed in the user directory after the gnome settings. Will post my findings... probably not before weekend.

Ahh, YaST and Kaffeine are based on Qt 3, which system settings does not change... why GNOME was able to affect them though would be very interesting.

Is there any trick how I can set the font size for qt3 apps with KDE4 if the KDE settings doesnt affect the qt3 apps ? A lot of qt apps are not yet ported so I guess not only openSUSE will ship KDE3 apps in KDE4 environment. Well, knowing this is not directly KDE4 issue but more the distributor's but it will affect the general appearance and usability for KDE4.

It also looks like that in KDE appearance setting the "use KDE fonts in Gtk apps" doesn't show any effect - e.g. GIMP or Firefox was only readable after I used the gnome settings tool.

I believe you can use KControl from KDE 3 to configure Qt3, Support for setting Qt3 settings from System Settings will probably never be added due to Qt3 being near its End Of Life
