[Qt-interest] Highlighting button in TableView

[Guido Seifert]

What you want to do is not that easy. Your delegate draws the button when the delegate editor opens, i.e. your Qt::ItemDataRole is Qt::EditRole. When in Qt::DisplayRole the delegate lets the cell draw itself. To see a button you have to overload the delegate's paint function to draw the button yourself.


At least this is one way, no idea if there is a better way to achieve what you want.

Guido
