Maybe it works under XP (did not try), but that is // meaningless because under XP a owner drawn tab control is already rendered *with* // the proper XP Styles. So, for XP there is no need to care about the theme API at all. // // However, under Vista, a tab control which has the TCS_OWNERDRAWFIXED // style gets additional 3D-borders which are applied by Vista *after* WM_DRAWITEM // was processed. Thus, there is no known workaround available to prevent Vista from // adding those old fashioned 3D-borders. We can render the tab control items within // the WM_DRAWITEM handler in whatever style we want, but Vista will in each case // overwrite the borders of each tab control item with old fashioned 3D-borders... // // To complete this experience, tab controls also do not support NMCUSTOMDRAW. So, the // only known way to customize a tab control is by using TCS_OWNERDRAWFIXED which does // however not work properly under Vista. // // The "solution" which is currently implemented to prevent Vista from drawing those // 3D-borders is by using "ExcludeClipRect" to reduce the drawing area which is used // by Windows after WM_DRAWITEM was processed. This "solution" is very sensitive to // the used rectangles and offsets in general.
