Layout Problem

[kris5228]

Hello,

I want to make it so there are buttons in the left side with a BoxLayout and a textarea that covers the right side. This is my progress so far and I don't understand why it doesn't work.

public void sets() {
		JFrame frame = new JFrame(title);
		frame.setVisible(true);
		frame.setSize(400, 400);
		frame.setMinimumSize(new Dimension(400, 400));
		frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
		frame.setResizable(true);
		frame.setLayout(new BorderLayout());
		
		JButton button1 = new JButton("Essay");
		JButton button2 = new JButton("Novelle");
		JButton button3 = new JButton("Artikel");
		JTextArea textarea = new JTextArea();
		
		JPanel panel2 = new JPanel();
		panel2.setLayout(new BoxLayout(panel2, BoxLayout.PAGE_AXIS));
		panel2.setBorder(BorderFactory.createEmptyBorder(10, 10, 10, 10));
		panel2.add(textarea);
		
		JPanel panel = new JPanel();
		panel.setLayout(new BoxLayout(panel, BoxLayout.PAGE_AXIS));
		panel.setBorder(BorderFactory.createEmptyBorder(10, 10, 10, 10));
		panel.add(button1);
		panel.add(Box.createRigidArea(new Dimension(0,10)));
		panel.add(button2);
		panel.add(Box.createRigidArea(new Dimension(0,10)));
		panel.add(button3);

		frame.add(panel, BorderLayout.WEST);
		frame.add(panel2, BorderLayout.EAST);
		frame.pack();
	}

Panel2 or the textarea doesn't seem to be showing, why is that?

You are adding components after the parent container (JFrame) has been realized (set to visible). a) Call validate/revalidate followed by repaint when changing the components in this manner or b) (and better practice) add them prior to calling setVisible and pack

Putting

frame.setVisible(true);

at the end after frame.pack(); doesn't seem to fix the problem either. The Buttons are showing up but the textarea aren't.

How do you know its 'not showing up'? Debug by adding some text to the text area, or set a color border around it to be sure it is 'showing up'.

Sorry, you're correct, it is working now thanks. Though you got me interested when you said a color border. What is the code for that?
