fine-tuning my Gui...

[thejaswini ramesh]

Hi everyone,
I need some help to fine tune my gui.I have a panel wherein in the user enters some parameters to make a tcp/ip connection.Once the user clicks the "connect" button,I want all the components in the panel to be disabled.In the panel I have 5 textboxes and 3 comboboxes.The text boxes, i have used
text.setEnable(false);
in the listener for "connect".But the comboboxes can still be clicked even when the connection is made.How can i prevent the user from changing any of the parameters after they are set and the connection is made?

On the same lines, I have 2 radiobuttons and a checkbox.I want the insides of these(the circle and the box)to be transparent.By default it has the color of the panel.Can someone give me an idea on this.

Thanks in advance,
Thejaswini.

Hi thejaswini,

You can use setEnabled (false) on the JCombo box to make it look greyed out.

Borrowing Michael Dunn's answer on the JComboBox question in this list, I did this:

class TestiButtonDisables extends JFrame implements ActionListener
{
  JButton jb = new JButton ("Do It!");
  JCheckBox jcb = new JCheckBox ("check box");
  JRadioButton jrb = new JRadioButton ("radio button");
  JComboBox cbo = new JComboBox(new String[]{"London","Madrid","New York","Rome","Sydney"});
 
  public TestiButtonDisables()
  {
    setSize(150,200);
    setLocation(400,300);
    setDefaultCloseOperation(EXIT_ON_CLOSE);
    JPanel jp = new JPanel();
    jp.setBackground(Color.RED);
    //cbo.setEditable(true);
    cbo.setOpaque(false);
    makeTransparent(cbo.getComponents());
 
    jrb.setOpaque(false);
    makeTransparent(jrb.getComponents());
 
    jcb.setOpaque(false);
    makeTransparent(jcb.getComponents());
 
    jp.add(cbo);
    jp.add (jb);
    jp.add (jrb);
    jp.add (jcb);
    getContentPane().add(jp);
    jb.addActionListener (this);
  }
  public void makeTransparent(Component[] comp)
  {
    for(int x = 0; x < comp.length; x++)
    {
      if(comp[x] instanceof javax.swing.plaf.metal.MetalComboBoxButton)
      {
        ((javax.swing.plaf.metal.MetalComboBoxButton)comp[x]).setOpaque(false);
        ((javax.swing.plaf.metal.MetalComboBoxButton)comp[x]).setBorder(null);
      }
      else if(comp[x] instanceof JTextField)
      {
        ((JTextField)comp[x]).setOpaque(false);
        ((JTextField)comp[x]).setBorder(null);
      }
    }
  }
 
    public void actionPerformed(ActionEvent ae) {
      System.out.println ("actionPerformed");
      cbo.setEnabled (false);
      jrb.setEnabled (false);
      jcb.setEnabled (false);
    }
 
  public static void main(String args[]){new TestiButtonDisables().setVisible(true);}
}

Thank you very much Eddie.The setEnabled(false) method is working fine.
