◆ TQConnection() [1/4]

TQConnection::TQConnection ( )
inline

Definition at line 82 of file TQConnection.h.

◆ TQConnection() [2/4]

TQConnection::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

Definition at line 454 of file TQConnection.cxx.

◆ TQConnection() [3/4]

TQConnection::TQConnection ( const char *  class_name,
void *  receiver,
const char *  funcname 
)

TQConnection ctor.

Creates connection to method of class specified by name, it could be interpreted class and with method == funcname.

Definition at line 478 of file TQConnection.cxx.

virtual

TQConnection dtor.

  • remove this connection from all signal lists
  • we do not delete fSlot if it has other connections, TQSlot::fCounter > 0 .
