Noneditable Combo

[Sridevi Sangaiah]

Hi all,

I have a noneditable combo, say with drop down values 1,2,3,4 and at one point of time, i need to have a value 5 to be selected in the combobox, but i should not add it to the combobox dropdown. Since because it is a non editable combo, i cant say setSelectedItem of a particular value which is not added to the combobox dropdown.

I require an immediate solution for this.

Thanks & Regards
Sridevi

I don't understand. You want to select a value that doesn't exist and not add it to the JComboBox?

    setTitle("Test GUI");
    setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    setLocationRelativeTo(null);
    Container frame = getContentPane();
    frame.setLayout(new FlowLayout(FlowLayout.CENTER));
    btn.addActionListener(this);
    frame.add(cb);
    frame.add(btn);
    pack();
  }
  public void actionPerformed(ActionEvent ae)
  {
    cb.setEditable(true);
    cb.setSelectedItem("5");
    cb.setEditable(false);
  }
  public static void main( String args[] ){new TestGUI().setVisible(true);}
}
