*All* widgets receive *events* from mouse clicks, which can be handled 
by subclassing and overriding the event function, or by installing an 
event handler.

Some widgets, by default, handle events by emitting corresponding 
signals. This is done for widgets where the specific events need *often* 
to be handled (eg: a click for a button), so that the user can customize 
the behaviour by connecting a slot.

In you case, Trolltech decided that QLabel usually don't need click to 
be handled, so they didn't provide a standard event handler which emits 
a standard signal for it. But you can do it yourself, in your own 
QClickableLabel, though.
