How to get class function names list? Qt C++

Question

For example I do have this code:

class MyClass : public QObject
{
    Q_OBJECT
public:
    void MyClass()
    {
    QStringList selfFunctionList;
    //Get functions list
    qDebug()<<selfFunctionList;
    }
    void function1(){}
    void function435(){}
};

How do I set to selfFunctionList list of "function1" and "function435"?

Answer 1

You can use the staticMetaObject for that.

class Test : public QObject
{
    Q_OBJECT
public:
    explicit Test(QObject *parent = 0) :
        QObject(parent)
    {
        for (int n = 0; n < staticMetaObject.methodCount(); n++) {
           functions.append(QString::fromLocal8Bit(staticMetaObject.method(n).name()));
        }
        qDebug() << functions;
    }

signals:
    void testSignal();

private slots:   
    void privateTestFunction() {}

public slots:   
    void publicTestFunction() {}

private:
    QStringList functions;
};

One condition, the functions need to be declared as slots or signal.

Output:

("destroyed","destroyed","objectNameChanged","deleteLater","_q_reregisterTimers",
"testSignal","privateTestFunction","publicTestFunction")

Answer 2

C++ does not have the sort of self-awareness ( reflection ) you seem to want here. That is, there is no programmatic way to get the string name of a function and enter it into a container without hand-coding it. Qt does a very limited amount of this with its signals and slots, but not functions in general. So you will have to write

MyClass::MyClass(...)
{
   selfFunctionList << function1 << function345 << ... etc.
}

as the constructor, or something thing similar.

Edit : OP brought these macros to my attention which give you a bit of introspection, but implementing them to solve OP's problem would be far more arduous than the above, see comments.
