My very first theme. It's made for DexterMagnific's QuantumStyle SVG engine. This engine currently is a big buggy and incomplete, so my theme also is.
1) Make sure you have QuantumStyle installed. If not, get it here: http://kde-look.org/content/show.php/QuantumStyle?content=101088
2) Exctract the archive into /home/user/.config/QuantumStyle/ . You should have the directory "SimpleGray" there.
3) Write the line theme=SimpleGray in the file /home/user/.config/QuantumStyle/quantumstyle.qsconfig . If it doesn't exist, create it.
4) You got it! Select "QuantumStyle" from KDE theme preferences or qtconfig.
