cannot convert 'QGraphicsObject*' to 'QObject*' in initialization

[rwtmoore@hotmail.com]

I got the following code from http://apidocs.meego.com/1.2/qt4/qtbinding.html (and many other places):


// Using QDeclarativeView
QDeclarativeView view;
view.setSource(QUrl::fromLocalFile("MyItem.qml"));
view.show();
QObject *object = view.rootObject();


Unfortunately it doesn't compile. I get this error message:

cannot convert 'QGraphicsObject*' to 'QObject*' in initialization

It looks like we're trying to cast a QGraphicsObject to a QObject. What is going on here?

Thanks in advance.

Use qobject_cast on the pointer returned by rootObject():

QObject * object = qobject_cast< QObject * >( view.rootObject() );

QObject * object = qobject_cast< QObject * >( view.rootObject() );

To copy to clipboard, switch view to plain text mode 

As always, check the pointer returned by this operation to ensure it is non-NULL.
