Qt property system: access enumerations as string

lfdm

Hi fellows!

I have probably a novice question in here. I'm using the property system to share settings between different class.

I need an enumeration and basically followed the documentation example:
@class MyClass : public QObject
{
Q_OBJECT
Q_PROPERTY(Priority priority READ priority WRITE setPriority NOTIFY priorityChanged)
Q_ENUMS(Priority)

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

 enum Priority { High, Low, VeryHigh, VeryLow };

 void setPriority(Priority priority)
 {
     m_priority = priority;
     emit priorityChanged(priority);
 }
 Priority priority() const
 { return m_priority; }

signals:
void priorityChanged(Priority);

private:
Priority m_priority;
};@

@MyClass *myinstance = new MyClass;
QObject *object = myinstance;

myinstance->setPriority(MyClass::VeryHigh);
object->setProperty("priority", "VeryHigh");@

Where I don't find information is how to get in this case "priority" returning for example "VeryHigh" this QVariant instead of 2
@object->property("priority").toString() == "VeryHight";@

Or did I get it wrong?

Thanks for any help,

One thing I found (of course from web) is

@
#include <QMetaObject>
#include <QMetaEnum>

QMetaObject metaObject = MyClass::staticMetaObject;
QMetaEnum metaEnum = metaObject.enumerator( metaObject.indexOfEnumerator( "Priority" ) );

MyClass* myinstance = new MyClass( 0 );
myinstance->setPriority( MyClass::VeryHigh );
QString enumVal = QString( metaEnum.valueToKey( myinstance->property( "priority" ).toInt() ) );

@

The other way would be constructing a method to convert enum to QString kind of mapping method to map enum value to respective QString.

Thanks!

I'll give it a go.
