showInputDialog Formatting

Question

I'm trying to figure out Java's JOptionPane.showInputDialog look and feel, more specifically, the commented line below:

final JDialog dialog = new JDialog();
    dialog.setAlwaysOnTop(true);  
 // OptionPane.background("blue");
    JOptionPane.showInputDialog(dialog, "Dialog");

How do I correctly use that line?

Answer 1

you should try this

dialog.getContentPane().setBackground( Color.blue );
