I'm pretty sure the general method would be as follows:

1. Create a QFrame that will serve as a wrapper; pass it the widget you wish to 'select'
2. Place the wrapped widget in a layout; this will be the QFrame widget's layout.
3. Overload the functions for a mouse double-click event and a paint event, so that on selection parts of the border are painted.
