Constructor & Destructor Documentation

◆ TQSlot() [1/2]

TQSlot::TQSlot ( TClass cl,
const char *  method_name,
const char *  funcname 
)

Create the method invocation environment.

Necessary input information: the class, full method name with prototype string of the form: method(char*,int,float). To initialize class method with default arguments, method string with default parameters should be of the form:

method(="ABC",1234,3.14) (!! parameter string should consists of '=').

To execute the method call TQSlot::ExecuteMethod(object,...).

Definition at line 101 of file TQConnection.cxx.

◆ TQSlot() [2/2]

TQSlot::TQSlot ( const char *  class_name,
const char *  funcname 
)

Create the method invocation environment.

Necessary input information: the name of class (could be interpreted class), full method name with prototype or parameter string of the form: method(char*,int,float). To initialize class method with default arguments, method string with default parameters should be of the form:

method(="ABC",1234,3.14) (!! parameter string should consists of '=').

To execute the method call TQSlot::ExecuteMethod(object,...).

ExecuteMethod the method for the specified object and with several argument values.

ParamArr is an array containing the function argument values. If nparam = -1 then paramArr must contain values for all function arguments, otherwise Nargs-NargsOpt <= nparam <= Nargs, where Nargs is the number of all arguments and NargsOpt is the number of default arguments.
