Just thinking out loud:<br>
How about adding an</div>

to KdePlatformTheme?<br>
<br>
We could then try to load the KDE library at runtine in QKdeTheme::createKdeTheme(). If we can resolve the symbol, an application that doesn't even know from KDE could benefit from KdePlatformTheme.</div>

...and while at it, requestColorScheme() could also be re-implemented....</div>

Heh I did not expect that Qt would start to link KColorScheme library :D. But<br>
the output could be used to make default palettes for QKDETheme.<br>
<br>
Another option would be to just read the files during runtime. I see that<br>
QKdeThemePrivate::readKdeSystemPalette already can read colors from<br>
.config/kdeglobals which contain the colors of the currently active color<br>
scheme. The color scheme files in $GenericDataLocation/color-schemes/<br>
have the same format.<br>
