Is there a way to identify the widget sending a signal if I connect a bunch of different widgets to the same slot?

I have six QLineEdits on which I want to update the tools tip when the editingFinished () signal is sent. I would prefer to keep the processing to a minimum by only resetting the ToolTip for the edit that changed, rather than resetting all of them each time.

Actually, it's not the processing, it just feels wrong to do all of them when only one is necessary!
