Choice


A choice is a pull-down list. It is also called as combo box. The choice menu is used to display a list of choices for the user to select from. The choice menu is selected by mouse click on the choice control, alist of options drops down.
To create a choice, first create a constructor, and the populate the choice by repeatedly calling addItem().

int getItemCount()  - returns the number of items in the choice menu.
void select(int position)  - select the item at the given position.
String getItem(int index)  - return the text of a given item.

Example:

import java.applet.*;
import java.awt.*;
public class ChoiceDemo extends Applet 
{
    public void init()
    {
        Choice color=new Choice();
        color.add("Red");
        color.add("Green");
        color.add("Blue");
        add(new Label("normal appearance"));
        add(color);
    }        
}
/*
 * <applet code="ChoiceDemo.class" width=300 height=150>
 * </applet>
 */
