I have a JTextArea and it's riding ontop of a JScrollPane. Anyways, I know I can use the `getViewPort()` method to set the opaque of of the view port... but I cannot seem to find any sign of how to do that... anywhere. :S

Here is what I have so far:
     if (e.getKeyCode() == KeyEvent.VK_F)
    {
    	if (sp.isVisible())
    	{
    		sp.setVisible(false);
    	}
    	else
    	{
    		sp.setVisible(true);
    	}
    }

Maybe I can set the background of a JScrollPane to a .gif image which is 50% transparent?

I'm guessing r,g,b is an int ... should be like:
c.setBackground(new Color(255,255,255, 127));
