Calling an object factory method from QML (and getting the QDView)
-
Hi,
I am winrking in a project where I have a class A that inherits from QDeclarativeItem.
What I want, is to have an instance of my class A (displayed somewhere on the qml window) and when I click on this one instance (lets call this instance "factory instance"), it create a new instance of the class A.
Thus, I made a static method in the class A that looks like this:
@
A* A::AFactory(QDeclarativeView* v,
QDeclarativeItem* parent){
QDeclarativeComponent component(v->engine(), QUrl("test.qml"));
A *a = qobject_cast<A >(component.create());
qDebug() << component.errors();
a->setParentItem(parent);
return a;
}
@
What I want to do is to call this method from QML, like this, for example (here I just want to create it when clicking on the background, not in the "facotry instance"):
@
Rectangle{
color: "blue"
id: base
width: 200
height: 200
MouseArea{
anchors.fill: parent
onClicked: {factory.AFactory(view,base);}
}
A{
id: factory
}
}
@In irder to get the view, I have done
@
QDeclarativeView* view = new QDeclarativeView;
view->setSource(QUrl::fromLocalFile("Base.qml"));
QDeclarativeContext* cxt = view->rootContext();
cxt->setContextProperty("view",view);
@
in my main function.
As I result, I do have the view in QML (with a console.log(view) in QML I can display its address and it is the same than from C++) but QML does not get it really well... The rror is:
Error: Unknown method parameter type: QDeclarativeView*I believe that what I am tring to do is quite complicated... Is there another way to do it more easily? Or is there a solution to my issue?
Thank you a lot!
