[Qt-interest] making QPushButton appear next to the selected item in a QTableView

[TP]

Hello,

I am trying to figure out how to make a widget like a QPushButton appear 
next to the selected item in a QTableView.

Up to now, my approach is to create a QPushButton in the paint() method of a 
custom QItemDelegate set on the QTableView.
The parent of the QPushButton is the QTableView.
I use the QStyleOptionViewItem QRect to determine how to move() the 
QPushButton next to the selected item in the QTableView.

The biggest problem is that I want to put the QPushButton not really in the 
viewport of the QTableView, but rather in the table! This means, that if I 
scroll down the table to the bottom, and make the QPushButton appear by 
clicking on a cell, and then I scroll up the table, I want the QPushButton 
to disappear.
But on the contrary, with my current code, it remains in the viewport. I 
don't know how to do that. What is the best method to use?

Thanks

Julien
