Class Description

                                                                      
 TQConnection class is an internal class, used in the object          
 communication mechanism.                                             
                                                                      
 TQConnection:                                                        
    -  is a list of signal_lists containing pointers                  
       to this connection                                             
    -  receiver is the object to which slot-method is applied         
                                                                      
 This implementation is provided by                                   
 Valeriy Onuchin (onuchin@sirius.ihep.su).                            
                                                                      


TQConnection() : TList(), TQObject()
 Default constructor.

TQConnection(TClass *cl, void *receiver, const char *method_name) : TList(), TQObject()
 TQConnection ctor.
    cl != 0  - connection to object == receiver of class == cl
               and method == method_name
    cl == 0  - connection to function with name == method_name

TQConnection(const char *class_name, void *receiver, const char *funcname) : TList(), TQObject()
 TQConnection ctor.
    Creates connection to method of class specified by name,
    it could be interpreted class and with method == funcname.

~TQConnection()
 TQConnection dtor.
    - remove this connection from all signal lists
    - we do not delete fSlot if it has other connections,
      TQSlot::fCounter > 0 .

const char* GetName() const
 Returns name of connection

void Destroyed()
 Signal Destroyed tells that connection is destroyed.

void ls(Option_t *option) const
 List TQConnection full method name and list all signals
 connected to this connection.

void Print(Option_t *option) const
 Print TQConnection full method name and print all
 signals connected to this connection.

void ExecuteMethod()
 Apply slot-method to the fReceiver object without arguments.

void ExecuteMethod(Long_t param)
 Apply slot-method to the fReceiver object with
 single argument value.

void ExecuteMethod(Double_t param)
 Apply slot-method to the fReceiver object with
 single argument value.

void ExecuteMethod(Long_t *params)
 Apply slot-method to the fReceiver object with variable
 number of argument values.

void ExecuteMethod(const char *param)
 Apply slot-method to the fReceiver object and
 with string parameter.
