GTK Style in KDE20 Nov 2008
GTK applications in KDE always look horrible. In Kubuntu this is taken care of for you, but in Debian it is only a quick install away:
$ sudo aptitude install gtk-qt-engine
There are other ways of achieving this, e.g. qtcurve, but for me this seems perfectly satisfactory. Having installed, you visit your control panel and you will find a new option under “Appearance & Themes” called “GTK Styles and Fonts” change this to use your KDE style for your GTK applications, and restart KDE.
