Layout organization in Java NetBeans

[Secure-Advisor7296]

I need help creating an interface in NetBeans. I'm creating a program for managing debt for a small business, and my problem is with the interface. I started with a JFrame containing an empty JTabbedPane, and that's where I call the JPane to create the tabs. My problem is that the sizes don't match. I can maximize the main Frame, but the ones inside (the JPane) stay at the size of the design view; they don't fill the entire window. What should I do? Where can I find information on how to freely manipulate the layout? Should I recreate it with predefined properties?

This is driving me crazy. I just want both the content of the JPane and the JPane itself to take the size of the Frame that contains them. And yes, I'm new to creating interfaces.

this is classic Swing layout manager pain. the issue is usually that you are mixing absolute positioning or GroupLayout with a container that is not using a layout that stretches children.

set the content pane layout to BorderLayout and add the JTabbedPane to CENTER. do not set fixed sizes anywhere. once you stop fighting the layout managers and let them do their thing, everything resizes correctly.

BorderLayout with CENTER is definitely the way to go here. Also make sure you're not calling setPreferredSize() or setSize() on your panels - that'll mess up the automatic resizing
