Hi Curt,

The problem is that QTableView does a reset of the selection in the 
mouseReleaseEvent() based on the current mouse position in the view. You 
need to reimplement mouseReleaseEvent() to keep on selecting what you want.

I don't get what you mean here. The index is always valid when you have 
the mouse inside the view.

best regards,
