    Default JComponents Are Wrong Size

    I'm making a program with a JFrame that has several sections separated by a JSplitPane. In the splits I'm putting my sections in their own JPanels. The problem is that I cannot size up the panels and they remain very small:

    Sample code looks like this:

    Java Code:
    JSplitPane RightColumn = new JSplitPane();
    			JPanel TopRow = new JPanel();
    				EditArea EArea = new EditArea();
    Java Code:
    public EditArea()
    		width = height = 100;
    		setSize(width, height);
    		image = new BufferedImage(width, height, BufferedImage.TYPE_INT_ARGB);
    		Graphics g = image.getGraphics();
    		g.fillRect(0, 0, width, height);
    So what about JPanels am I not getting? Why doesn't this work the way I think it will?

    You're not telling us the key information -- what layout managers are you using and how are you using them? Also, are you setting preferred size of your components?

    I'm using a border layout. The toolbar is BorderLayout.NORTH, the left side is BorderLayout.WEST, and the right is BorderLayout.CENTER. I didn't set preferred size but I used setSize and I thought that would work. I'll try preferred size.


    Ok that's it. These are the things they don't tell you in tutorials :P. Thanks!
