[Qt-interest] QListWidget clicked() signal

[Martin Fiala]

Thank you very much for the reply.

So, just to be absolutely sure, there isn't any signal that is emitted
when the widget is clicked or activated? I don't really need to know
if there was an item clicked or which one was clicked etc.. Just to
know which of the two widgets was clicked... It just seems
unbelieavable to me as I can see the widget react on the click even if
there are no items (the frame of widget changes)..
If so I might have to look into those overloads......
Thanks again for your quick response.
