Hi,

A JComboBox.AccessibleJComboBox class implements accessibility support for the JComboBox class. It provides an implementation of the Java Accessibility API appropriate to Combo Box user-interface elements. The 'JComboBox.AccessibleJComboBox class' implements AccessibleAction, AccessibleComponent, AccessibleExtendedComponent, AccessibleSelection, Serializable interfaces.

Following java example will demonstrate you the use of JComboBox.AccessibleJComboBox class:

import javax.swing.JComboBox.AccessibleJComboBox
import javax.swing.JFrame;

public class JCAMain extends JFrame 
{
  JComboBox combo01 = new JComboBox();

  public JCAMain() {
    setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

    combo01.addItem("A");
    combo01.addItem("H");
    combo01.addItem("P");
    combo01.setEditable(true);
    System.out.println("#items=" + combo01.getItemCount());

    combo01.addActionListener(new ActionListener() {
      public void actionPerformed(ActionEvent e) {
        System.out.println("Selected index=" + combo01.getSelectedIndex()
            + " Selected item=" + combo01.getSelectedItem());
      }
    });

    getContentPane().add(combo01);
    pack();
    setVisible(true);
  }

  public static void main(String arbg[]) {
    new JCAMain();
  }
}

Hi,

In following example I have used methods of 'JComboBox.AccessibleJComboBox class' for to add the new item to the JComboBox:

import javax.swing.JFrame;
import javax.swing.JComboBox.AccessibleJComboBox;

public class AddingItemToComboBoxDM {

  public static void main(String[] a) {
    JFrame zlp = new JFrame();
    zlp.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

    JComboBox jComboBox01 = new JComboBox();
    jComboBox1.addItem("asdf");
    Object cmboitem1 = jComboBox01.getSelectedItem();
    System.out.println(cmboitem1);

    zlp.add(jComboBox1);

    zlp.setSize(200, 200);
    zlp.setVisible(true);
  }

}
