[Qt-interest] QCheckBox as editor in QTreeView

[Daniele Esposti]

Hi Andre,

yes, of course, I can also use the CheckStateRole to do that in a more
simple and fancy way. The point is I'm using a delegate to create
different editors (from base text, checkbox, etc. to more costumised
ones) and I found that problem with the QCheckBox widget.
