Inheritance in Qt

[A Former User]

Hi devs!

This is what I'm trying to do: the class A inherits from B. This the code:

@// class B.h

public:
explicit B();

// class B.cpp

B::B() {...}

//class A.h

class A : public B
{
Q_OBJECT
public:
explicit A(QObject *parent = 0);

//class A.cpp

A::A(QObject *parent) : B(parent)@

This doesn't work. Please help me!

Since B is not a QObject, and does not have a constructor that accepts QObject argument (see the last line of your code snippet), it will not work. You can just skip the B(parent) call and it should be ok.

Also, don't use the Q_OBJECT macro if your class doesn't inherit QObject.
