[Qt-interest] paint emtpy selected cell from QItemDelegate with a custom editor

[wim.delvaux at adaptiveplanet.com]

Hi,

I have this item delegate that returns a custom widget as editor for a certain 
cell.

However that widget has a transparent background. and paints itself on top of 
the 'static' content of the cell (i.e. the value that is in the cell without 
editor).

I want to paint the widget on an 'empty' background. That background is 
generally 'selected'.

I have set setBackgroundRole on the widget while setting setAutoFillBackground 
to TRUE but to avail.  previous content is not erase.

How can I do this ?

Thx
