Style plugin

[GrahamL]

Hi
I am trying to follow the style plugin example given here -
http://qt-project.org/doc/qt-5.0/qtwidgets/tools-styleplugin.html
The docs state that
Note: On some platforms, the native style will prevent the button from having a red background. In this case, try to run the example in another style (e.g., fusion).

And indeed on my Windows 7 box the color of the button is unchanged.

Does this mean that there is no way to change the backgound color of a widget using style plugins on windows?

Thanks
