Hi

I can see how to use a ImageView, or any other QML declared object, declared in QML from the constructor method that creates the scene using the QML document and then sets the AbstractPane root. But how do I access an ImageView from anywhere else in the same class? Shall I keep a reference to the root or the QML-document?

You can call Application::instance()->scene() and cast it to your top level object type, something like this:

Page *appPage = (Page *)Application::instance()->scene();
Camera *camera = appPage->findChild<Camera *>("myCamera");
etc

Or keep the pointer to appPage and/or other controls in member variables. This way the code will be cleaner.

Thanks for the tip. I think I will go for the solution with keeping references to the few objects I need.

Yeah, your best bet is to just keep a reference to your AbstractPane then use findChild

ListView *redditCommentsList = m_AbsPane->findChild<ListView*>("commentsList");
