How to dynamically control auto-resize components in Java Swing

Question

Creating a new GUI in Java (1.8) Swing, I am searching for a way to override resize behavior of all my components.

Let me explain to you with some edited photos:

This is how I do it and I am not sure this is the proper way:

First set the layout to null.

Next create a component resized event for your frame:

addComponentListener(new ComponentAdapter(){
            public void componentResized(ComponentEvent e){
            }
        });

Inside here you can manually make changes to the components as it is resized. I have done this for a few of my programs to keep a scroll pane on the left and right of the frame always the same width and have everything else size up and down as resized.
