◆ 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,...).
