Qt moc with implementations inside of header files?

Question

Is it possible to tell the Qt MOC that I would like to declare the class and implement it in a single file rather than splitting them up into an .h and .cpp file?

Answer 1

If you want to declare and implement a QObject subclass in you cpp file, you have to manually include the moc file.

For example: (file main.cpp)

struct SubObject : QObject
{
    Q_OBJECT
};

//...

#include "main.moc"

You have to rerun moc (make qmake) after adding the #include statement.

Answer 2

I think you can normally declare and implement the class in the header file without using anything special, eg:

include

class MyClass : public QObject { Q_OBJECT

public: MyClass(QObject * parent) { // Constructor Content }

 methodExample()
 {
      // Method content
 }

};

After this you add the header file to the pri file and execute qmake again and that's it. You have a class that inherits from qobject and is implemented and declared int he .h file.
