When a signal or slot is overloaded, QtScript will attempt to pick the right overload based on the actual types of theQScriptValuearguments involved in the function invocation. For example, if your class has sl
In particular, constructors should not call virtual functions, attempt to raise errors, access potentially uninitialized global variables, etc. Default Constructors link ▶You must define a default constructor if your class defines member variables and has no other constructors. Otherwise the compiler...
