oxygen-style-animated is a branch of trunk/KDE/kdebase/runtime/kstyles/oxygen that introduces smooth animations for the Oxygen widget style.
The code is organized as follow:
1/ oxygenstyle.h and .cpp derive from QCommonStyle and take care of all the painting. All 'primitives' are implemented as separate functions with identical prototypes and mapped to the corresponding QStyle primitive element at initialization style.
Some of the painting routines have been moved in oxygenstylehelper, for re-usability. Additionaly some code that is common to the widget style and the window decoration resides at kdebase/workspace/libs/oxygen.
