Using BoxLayout to resize JPanels in GUI : <p>I currently have this code I am working with:</p>

<pre><code>this.getContentPane().add(wwjPanel, BorderLayout.EAST);
        if (includeLayerPanel)
        {
            this.controlPanel = new JPanel();
            controlPanel.setLayout(new BoxLayout(controlPanel, BoxLayout.Y_AXIS));
            this.layerPanel = new LayerPanel(this.getWwd());
            this.controlPanel.add(new FlatWorldPanel(this.getWwd()),Box.createRigidArea(new Dimension(1000, 1000))); //This is the top pan
            this.controlPanel.add(this.getStates(), Box.createRigidArea(new Dimension(0, 100)));
            this.controlPanel.add(this.getPanelAlerts(), Box.createRigidArea(new Dimension(0,100)));

            this.getContentPane().add(this.controlPanel, BorderLayout.WEST);//This is the whole panel on the left
        }
</code></pre>

<p>I am trying to resize the JPanels, called controlPanel here, to each have their own unique size in my GUI. I am new to building GUIs with java, and the majority of the code I have is pulled from another file. The code I am trying to incorporate are these new panels as described in my code, and trying to resize them. Is BoxLayout what I want to be using to get my desired effect?</p>

<p>Also, when I use the createRigidArea it seems to work, but if I continue to change the x and y values you pass to it nothing seems to happen. What I mean by this is, that I don't see any visual difference by changing the values, and I have used values ranging from 0-1000.</p>

<p>Thanks.</p>
