Custom round leather gui

Question

Looking for a starting place to create a circular interface. I tried to study documents and tried to study other plugins for Eclipse. I am just starting to build gui with java, and all I find is either to ask me to be part of the company to use their product, or to want a few hundred dollars.

I'm just a humble coder trying my best at gui and the personal project I'm working on wants a round gui skin.

Answer 1

There are at least two ways to achieve this ...

Could you...

Use JFrame#setShapeto change the shape of the main window, for example ...

JFrame frame = new JFrame("Testing");
frame.getContentPane().setBackground(Color.RED);
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.setLayout(new GridBagLayout());
frame.add(new JLabel("Boo!"));
frame.setSize(200, 200);
frame.setLocationRelativeTo(null);
frame.setUndecorated(true);
frame.setShape(new Ellipse2D.Double(0, 0, 200, 200));
frame.setVisible(true);
