Need help for delegate.paint. Does not work for me ...

 

I have a model / view schema.
I’m developing a general multipurpose delegates, and I’d want to use some custom widgets I have.
The first I have tested does not work:

  1. void A_delegates::paint(QPainter* painter, const QStyleOptionViewItem & option,
  2.  const QModelIndex& index) const
  3. QRect the_rect(option.rect);    
  4. A_file_chooser file_chooser;
  5. file_chooser.setGeometry(QRect(QPoint(0,0), the_rect.size()));
  6. file_chooser.render(painter,the_rect.topLeft());

I see an empty cell ?
I have read the doc searching something usefull about this but without success.
Can anybody help me ? Thanks.

( the file chooser is as simple as a label plus a button. I can see it in other scenarios)

The widget, where you call render is invisble (show is never called). This implies, it is not painted.
