Accessing QML objects from C++

问题

Following is a code written to load a QML document to c++.

  QmlDocument *qml = QmlDocument::create("asset:///main.qml").parent(this);

    // Create root object for the UI
    AbstractPane *root = qml->createRootObject<AbstractPane>();


    app->setScene(root);
}

How do I access the objects of the QMLdocument, such as a button etc; from C++. I need to access them to find the memory address of a specific object in the QML document.

回答1:

ImageView* iv= root->findChild<bb::cascades::ImageView*>("myImageView");

and in QML

 ImageView 
 {
      // ...
      objectName: "myImageView"
 }

Edit: Don't forget to clean and rebuild the project.
