Slot with a return value?

[lalesculiviu]

Hello!

May I make a slot with a return value, like:

public slots:
    bool saveAs();
....
connect(savePB, SIGNAL(clicked()), this, SLOT(saveAs());

public slots:
    bool saveAs();
....
connect(savePB, SIGNAL(clicked()), this, SLOT(saveAs());

To copy to clipboard, switch view to plain text mode 

Practically, it works, but is this documented in Qt or allowed?
