Auto resizing of non-resizeable controls

Question

Is it possible to have controls which by default are not resizeable (e.g. ImageView, MediaView) to be automatically resized as their parent node is resized? If so, how can this be achieved?
Thanks,

Answer 1

It is possible, with a trick. What I do is wrap the ImageView into a ScrollPane, and then bind their properties together so that the ImageView tracks the size of the ScrollPane. Here's an example:
    ScrollPane scrollPane = new ScrollPane();
    scrollPane.setHbarPolicy(ScrollPane.ScrollBarPolicy.NEVER);
    scrollPane.setVbarPolicy(ScrollPane.ScrollBarPolicy.NEVER);
    scrollPane.setContent(new ImageView() {{
        imageProperty().bind(poster);
        setPreserveRatio(true);
        setSmooth(true);
        fitWidthProperty().bind(scrollPane.widthProperty());
        fitHeightProperty().bind(scrollPane.heightProperty());
    }});It shouldn't be too hard to change this into a generic Wrapper cllass that takes a ImageView or MediaView as parameter.
