QUndoView, how to know if the user clicked? it seems QAbstractItemView::clicked is not emitted :'(

mbruel

Hello,
I'm having an issue to know when the user of my app is clicking on the UndoView.
I would like to refresh my HMI when he does it.

The only place I've found so far would be to connect to QUndoStack::indexChanged but this doesn't go with what I want.

My app has a QGraphicsScene. When some stuff happens I fill the UndoStack BUT I don't want to refresh the scene.

I want to refresh it only on Undo/Redo and on a click on the UndoView.

It's easy to refresh when the user click on some Undo/Redo buttons but I don't find a way to intercept a click on the QUndoView.

Any ideas?
Cheers

on Linux 64bits, Qt.5.11.3, it seems that we need to click twice to have the signal QAbstractItemView::clicked.
First the new index is selected, then we have to click again to send the signal... Same with QAbstractItemView::activated

QAbstractItemView::pressed makes the job! Problem solved
