TableView with multiple columns, emit signal when whole row is selected

[Talei]

Hello,
I have TableView with i.e. 2 columns and n rows.
Currently I write text, via SIGNAL(clicked(QModelIndex)), to row that was clicked. Like this:
rows_one..jpg
But what I want also to implement, is to emit signal when entire row is selected. Like this:
rows..jpg

I tried SIGNAL(activated(QModelIndex)) but this is received only when user press enter.

As always thank you for any input/comments.
Best regards

Edit. Ideally I would want to emit signal when number, indicating tablerow number, is clicked (the one on the left side).
