I am using Ubuntu 10.04 64 bit and QT 4.6.3. QGroupBox borders in any Qt Application are not visible. I changed Ubuntu themes but borders are still not visible. I want them to be visible. How can I solve this?
Seems to me they depend on the "QStyle":http://doc.trolltech.com/latest/qstyle.html currently in use. This doesn't necessarily change when you change your theme in gnome (I think you're using gnome, since you mentioned ubuntu and not kubuntu, which are basically the same, but with a different desktop environment installed by default. (And yes, you can have kde on ubuntu.)) In kde the style is more likely to change with the environment since they're both Qt based.
Do I have to change QStyle currently in use.
Is there another way on Ubuntu side?
Have You tried using qtconfig to change the style used by Qt?
No but I wil give it a try
What graphics-theme on Ubuntu you have? May be that theme use its own QStyle with(out) borders.
