class TQConnection: public TList, public TQObject

TQConnection class is an internal class, used in the object
communication mechanism.

-  is a list of signal_lists containing pointers
to this connection
-  receiver is the object to which slot-method is applied

Function documentation

 Default constructor.
TQConnection(TClass* cl, void* receiver, const char* method_name)
 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* method_name)
 TQConnection ctor.
    Creates connection to method of class specified by name,
    it could be interpreted class and with method == funcname.
TQConnection(const TQConnection& con)
 Copy constructor. Ignore connections to this TQConnections
 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 (aka name of slot)
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 PrintCollectionHeader(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(Long64_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, Int_t nparam = -1)
 Apply slot-method to the fReceiver object with variable
 number of argument values.
void ExecuteMethod(const char* params)
 Apply slot-method to the fReceiver object and
 with string parameter.
Bool_t CheckSlot(Int_t nargs) const
 Return true if the underlying method is value and the number of argument
 is compatible.
void * GetSlotAddress() const
 Return the object address to be passed to the function.
CallFunc_t * LockSlot() const
 Lock the interpreter and mark the slot as executing.
void UnLockSlot(TQSlot* ) const
 Unlock the interpreter and mark the slot as no longer executing.
TQConnection & operator=(const TQConnection& )
void * GetReceiver() const
{ return fReceiver; }
const char * GetClassName() const
{ return fClassName; }
