Hi All,
I'm having trouble with assigning qml item properties in C++. The type is
declared in qml as a component, and is declared in another qml component as an
item property.
i.e.
TypeA.qml
QtObject {
property string myString
}
TypeB.qml
QtObject{
property TypeA myTypeA
}
I'm creating each of the objects on the c++ side using something like:
QString qml("import Qt 4.7\nTypeB{}\n");
QDeclarativeComponent component(engine);
component.setData(qml.toLatin1(), QUrl(""));
QObject *myTypeB = component.create();
And then wrapping the property using:
QDeclarativeProperty typeAProperty(myTypeB, "myTypeA", engine);
.. where typeAProperty.isValid() returns true, and if I do a
QDeclarativeProperty::read() I get a QVariant with a type of QVariant::QObject*
which casts to QObject* correctly.
However when I write the value, using :
...
QObject *myTypeA = component.create()
typeAProperty.write(QVariant::fromValue(myTypeA));
.. it returns false which I guess means the type is incorrect according to the
metatype, even though the QVariant's type is also QVariant::QObject*.
I know the object creation is working fine, as I can assign the object in the
root context to a context property, set string and int properties and they are
binding properly on the qml side. I couldn't find any examples in the
documentation that specifically dealt with item properties. I've managed to
get lists to work in a similar manner using QDeclarativeListReference, but the
convention for item properties seems subtly different.
Regards,
Simon.
