Set location of components and reduce the size

Question

I want to resize JavaFX component and shrink the components which are next to it. Here is the result which I get:
When I click on the angle of this component I can resize it down and right.

The components which are next to it are pushed down and right. Part of them are behind the visible part of the screen.

All components are placed in BorderPane,VBox,HBoxand againBorderPane. I don't want to allow components to move. I want to shrink them and use Scrollpane` when their size is reduced. Can you give me some hits how to solve these two problems?

Answer 1

I did something similar the other day. Based on the resizing of the scene I adjusted the position.
widthProperty().addListener(new ChangeListener<Number>() {
    @Override public void changed(ObservableValue<? extends Number> observableValue, Number oldSceneWidth, Number newSceneWidth) {
        widthChange((Double)oldSceneWidth, (Double)newSceneWidth);
heightProperty().addListener(new ChangeListener<Number>() {
    @Override public void changed(ObservableValue<? extends Number> observableValue, Number oldSceneHeight, Number newSceneHeight) {
        heightChange((Double)oldSceneHeight, (Double)newSceneHeight);
You should be able to do something similar, when you add a change listener to your component and handle the resizing of the other components.
What I don't understand is why you would need a scrollbar, when the components shrink down. I would think it would be the other way round.
