How to update QIcon on palette change?

[schrute]

How can I change QIcons already set on QPushButtons, QMenu etc on the application palette change?

Listen on QEvent::PaletteChange an apply your changes.

@Christian-Ehrlicher This should work for simple cases but what about complex widgets like QTreeWidget where icons are set using a decoration role in a model?

@schrute
At a guess then you need to tell it that the model data has changed for the decoration role, so that it redraws?
