I am using Nimbus L&F, and "control" is the background color of my dialog. If I set any other color (red in this example) it shows, but if I set it to this one, it's stays white.
I don't have tis problem on default (metal) L&F...
What's the problem?
For some reason, it doesn't seem to like the ColorUIResource object the is returned from UIManager.get call. I can't see why, because it's derived from Color.
If you do something like
JDialog dialog = new JDialog((JFrame) null, "Help", true);
dialog.getContentPane().setLayout(new BoxLayout(dialog.getContentPane(), BoxLayout.Y_AXIS));
JTextArea text = new JTextArea(10, 10);
Color color = new Color(UIManager.getColor("control").getRGB()); // <-- Create a new color
text.setBackground(bg);
dialog.add(text);
dialog.pack();
dialog.setLocationRelativeTo(null);
dialog.setVisible(true);
This seems to work.
Should you have to do it. I don't think so, but every thing else I tried didn't work
