well, you can't do SIGNAL "foo($variable)" since $variable can't be
interpreted at connect() time. Also, I don't think the "&" in
"&driveSelected()" is legal.

So, here's what you could do instead:

$driveView->connect(SIGNAL "clicked()", this, SLOT "driveSelected()");

In the driveSelected() slot, if you want to find out the current item,
you can call this->sender->currentItem(), or you could use your global
$MainWidget::driveView->currentItem(). Personally, I'd use
this->sender.
