JFreeChart hide behind other one

Question

I was trying to build UI in IntelliJ but it was hard so I tried to build it in Eclipse. Now UI looks little better but still poor. One of chart (the cener one) should be biger and second one on south should be smaller but flat and long. I tried to use preffered size or validate or repaint but still nothing. How to anchor them to side borders, and avoid to cover them self?

Answer 1

As your code is not MCVE I could not run it with changes, but I think your problem is bad layout settings. For example, you create a new JPanel:

JPanel jpSouth = new JPanel();
FlowLayout flowLayout_1 = (FlowLayout) jpSouth.getLayout();
flowLayout_1.setAlignment(FlowLayout.TRAILING);

You are aware that it is using FlowLayout by defaul, by later you use:

jpSouth.add(jfcPanelSouth,BorderLayout.CENTER);

but you never change layout to BorderLayout. You cannot mix layout of one particular container. But this is not what couse you problem directly.

Your BorderLayout.SOUTH area stretch horizontally, to fit components inside, and BorderLayout.CENTER takes all spece left(or not). This is how those parts of BorderLayout works. So you can change where you put particular components, or change layout at all.

I suggest to try with:

JPanel jpCenter = new JPanel(new BorderLayout());
...
jpCenter.add(jfcPanelCenter,BorderLayout.NORTH);
...
jpCenter.add(jfcPanelSouth,BorderLayout.SOUTH); //not to contentPane!

this will change an arrangement. However I am not sure, is it what you want. If not, try with different layout, for example BoxLayout. Also I would rather use pack() and set size of components, than setBounds on a countainer.

You can also use GUI builders, like Netbeans IDE GUI Builder if you want to create GUI but don't care how.
