12.1.10.5.17. Plot style sheets

This demo shows how you can set and change the theme of your GUI. The style can not be entirely removed to the windows, mac or plastique style (usually done by setStyle(new QWindowsStyle())). It only resets the style sheet to an empty one, such that the native fallbacks to the os dependent style is applied. However, Qt::WA_StyledBackground is still active.
