I use mostly GTK+ applications (eg. Geeqie, Audacious, etc.) on Lubuntu. However, I decided to give KDE 4 a try by installing kubuntu-desktop
and then removing the apps I didn't want.
Big mistake. Now, even when I'm running LXDE with the Qt applications running QGtkStyle, apps like K3b use Windows/KDE button order in dialog boxes rather than the GNOME/OSX-style button order used by standard GTK+ dialogs.
How do I force Qt applications back into using the GNOME-style button order for dialog boxes?
(Ideally, in a manner strong enough that it'll stay in effect even if I log into KDE, since 90% of my applications are GTK+ ones regardless of which desktop I run)
