Best way to implement a Button for an action in a QTableView

[Andy314]

I need a simple QPushButton in all rows in a specific column which performs an action (for the row).
I want no twice click to first enable an editor and then click the button.

There seem a lot of possible methods - what method is common used.

I'd implement a delegate that does the painting and nothing else and connect a slot to QAbstractItemView::clicked to handle the event as you don't have to worry about identifying what button was clicked
