Class Description

                                                                      
 This is the ROOT implementation of the Qt object communication       
 mechanism (see also http://www.troll.no/qt/metaobjects.html)         
                                                                      
 Signals and slots are used for communication between objects.        
 When an object has changed in some way that might be interesting     
 for the outside world, it emits a signal to tell whoever is          
 listening. All slots that are connected to this signal will be       
 activated (called). It is even possible to connect a signal          
 directly to another signal (this will emit the second signal         
 immediately whenever the first is emitted.) There is no limitation   
 on the number of slots that can be connected to a signal.            
 The slots will be activated in the order they were connected         
 to the signal. This mechanism allows objects to be easily reused,    
 because the object that emits a signal does not need to know         
 to which objects the signals are connected.                          
 Together, signals and slots make up a powerfull component            
 programming mechanism.
