Writing QSS for custom widgets is not really supported.

You can make it work though the following cases :
1. If your widget can be completely styled using QStyle and it uses
primitives, controls that are already defined in QStyle (i.e if you
define your own elements, it won't work).

2. If you are only looking for colors/brushes, you can set the
stylesheet and your widget's palette() will have the appropriate brushes.
