QTreeView and ItemDelegate style problem

[Guilo]

Hi !

I am using a QTreeView with a item delegate for all the columns but the first one. Usually when you mouse over a line in a QtreeView, the whole line is hghlighted. Here it stops at the non delegated columns (see attached picture). I think that I should change something in paint() of my delegate but I can't find what.

Thanks to help me.
