18.13 java.awt.Choice (JDK 1.0)

This class represents an "option menu" or "dropdown list." The addItem() method adds an item with the specified label to a Choice menu. getSelectedIndex() returns the numerical position of the selected item in the menu, and getSelectedItem() returns the label of the selected item.

public class Choice extends Component implements ItemSelectable {
    // Public Constructor
            public Choice();
    // Public Instance Methods
        1.1 public synchronized void add(String item);
            public synchronized void addItem(String item);
        1.1 public synchronized void addItemListener(ItemListener l);  // From ItemSelectable
            public void addNotify();  // Overrides Component
        #   public int countItems();
            public String getItem(int index);
        1.1 public int getItemCount();
            public int getSelectedIndex();
            public synchronized String getSelectedItem();
        1.1 public synchronized Object[] getSelectedObjects();  // From ItemSelectable
        1.1 public synchronized void insert(String item, int index);
        1.1 public synchronized void remove(String item);
        1.1 public synchronized void remove(int position);
        1.1 public synchronized void removeAll();
        1.1 public synchronized void removeItemListener(ItemListener l);  // From ItemSelectable
            public synchronized void select(int pos);
            public synchronized void select(String str);
    // Protected Instance Methods
            protected String paramString();  // Overrides Component
        1.1 protected void processEvent(AWTEvent e);  // Overrides Component
