QTreeWidget, resizing item and widgets problem

[The Storm]

Of course you do. Each cell is painted using a delegate and the default delegate is QItemDelegate or QStyledItemDelegate since Qt 4.4.


Try changing the palette of the frame (especially the Window role) to see if the background of the frame gets painted.

I hope that this is what you meant (attached picture) and how can I be sure that this QItemDelegate doesn't paint anything while there is widget on it.
