[Qt-interest] Retrieve a particular item from the QTreeView

[Constantin Makshin]

I can't say for sure what's the difference, but my guess is that pressed() is emitted when a mouse button is pressed and clicked() — when it's released.

And you don't have to override mousePressEvent() as signals emitted by item views and selection models are more convenient, particularly because they provide index of the selected item.
