How can we convert enum to int?

[ecanela]

Qt has a powerfull introspection system. using QMetaObject can access to all data generated for MOC.
enums, properties, signals and slots declared in the class

the follow code get the the values of the enum ViewportAnchorin the class QGraphicsView

#include <QApplication>
#include <QMetaEnum>
#include <QMetaType>
#include <QGraphicsView>
#include <qDebug>
 
 
int main(int argc, char *argv[])
{
    QApplication a(argc, argv);
 
    QGraphicsView * examples = new QGraphicsView;
 
    const QMetaObject * dataObject =  examples->metaObject();
 
    //get the index of the "ViewportAnchor" enum in the dataObject
    int indexViewport = dataObject->indexOfEnumerator("ViewportAnchor");
    QMetaEnum enumData = dataObject->enumerator(indexViewport);
 
    qDebug() << "Values of enum " << enumData.name();
    for (int x = 0; x < enumData.keyCount(); ++x)
      qDebug() << enumData.valueToKey(x);
 
    return a.exec();
}

#include <QApplication>
#include <QMetaEnum>
#include <QMetaType>
#include <QGraphicsView>
#include <qDebug>


int main(int argc, char *argv[])
{
    QApplication a(argc, argv);

    QGraphicsView * examples = new QGraphicsView;

    const QMetaObject * dataObject =  examples->metaObject();

    //get the index of the "ViewportAnchor" enum in the dataObject
    int indexViewport = dataObject->indexOfEnumerator("ViewportAnchor");
    QMetaEnum enumData = dataObject->enumerator(indexViewport);

    qDebug() << "Values of enum " << enumData.name();
    for (int x = 0; x < enumData.keyCount(); ++x)
      qDebug() << enumData.valueToKey(x);

    return a.exec();
}

for use this system in our class in necesary use the macro Q_ENUMS.

class MyClass : public QObject
 {
     Q_OBJECT
     Q_ENUMS(Priority)
 
 public:
     MyClass(QObject *parent = 0);
     ~MyClass();
 
     enum Priority { High, Low, VeryHigh, VeryLow };
     void setPriority(Priority priority);
     Priority priority() const;
 };

class MyClass : public QObject
 {
     Q_OBJECT
     Q_ENUMS(Priority)

 public:
     MyClass(QObject *parent = 0);
     ~MyClass();

     enum Priority { High, Low, VeryHigh, VeryLow };
     void setPriority(Priority priority);
     Priority priority() const;
 };

the previus post resolved the question,

i read wrong the question. but i hope someone find the post useful.

sorry my poor english
