Description Refilwe Seete 2009-10-08 22:33:17 UTC

If one adds the GNOME desktop to a KDE install the Qt interface will use the GNOME desktop's window title font for module titles (I believe it's Jakub Steiner's "Fifth Leg").

Reproducible: Always

Steps to Reproduce:
1. Install KDE desktop
2. Install GNOME desktop as well

Actual Results:  
Change in title font

Expected Results:  
No change in title fonts

This occurs in oS 11.2 Milestone 8.  It also occurs if one updates the system to Factory and then installs GNOME packages.

Actually you do not need to install GNOME packages, installing the fifthleg font on a KDE install is enough to cause the font to change as shown in the attached image.

Hi

I got the same ugly fonts on two updated systems from 11.1 to 11.2. the third system with a new installation got clean fonts.

I have checked a lot of rc-files, yast, qt..., but with no result.

Comment 5 Refilwe Seete 2009-11-07 16:56:56 UTC

I can reproduce this on openSUSE 11.2 RC2.

Once the "fifth-leg" font is installed, the YaST2 Qt fonts change as per the attached picture.

Comment 6 Thomas Göttlicher 2009-11-13 13:38:40 UTC

I guess YQApplication::headingFont() returns the fifth-leg.

Comment 7 Gabriele Mohr 2010-04-15 10:53:55 UTC

I did some tests to set the font family explicitly with QFont. But whatever set for the family the fifth-leg font is taken.
Jakub, to which family does the fifth-leg-font belongs to?

The Family of the font is set to 'FifthLeg', the generic being Sans-Serif. And yea at that size without proper hinting, the text looks hideous.

Comment 9 Gabriele Mohr 2010-04-22 12:55:52 UTC

I don't know yet where the font is selected. 
YQApplication::headingFont() isn't used because the headline of the dialog is set by UI::WizardCommand(`SetDialogHeading( title ) in Wizard.ycp. 
To set QFont explicitly, e.g. to Times in YQWizard::layoutWorkArea() has no effect (except 'bold' is used).
