[solved] Problem returning embeded custom type developt in Qt from within QML

[xardas008]

Hello guys,

I have a little problem. I have a class which looks something like this:
@
public class MyClass : public QObject {
Q_OBJECT
public:
Q_INVOKABLE RClock clock() const { return _clock; }
}
@

What I want to do in QML is, return the RClock element and access each of it's methods. So I thought to build a supclass of QObject, make each method Q_INVOKABLE and try in QML something like this:
@
function doSomething(){
var time = data.clock()
myHour.text = "" + time.hour()
...
}
@

But everything I get on the command line of Qt Creator is that time is undefined.

Anyone an idea what I'm doing wrong?

myHour is a Text element somewhere else in the QML file which should print the value of the hour of my custom clock.

Best regards

Did you register RClock as QML type with qmlRegisterType()?

[xardas008]

No, i only register the MyClass object to the view with @view->rootContext()->setContextProperty(myClassObject)@

and the RClock is embeded in MyClass so I should think that I can call the getter of MyClass returning the RClock and then calling RClock's getter methods to get the date and time stored as integer values in it.

How should I do it with qmlRegisterType()?? It's not a visual item which is not derived from QGraphicsViewItem

Ok I found out what I've forgotten.

I had to add the following to the qml file:
@
RClock {
id: myClock
}
@

And in RClock I added Q_PROPERTY's for each value.
And as you mentioned the qmlRegisterType() method was also needed.
Now everything works fine.
