This example program creates a combo box with 3 options. It has 2 listeners to handle 2 different types of events. A counter is used in the listener class to help to identify the order of events. If you run this program, you will see a combo box with 3 options: "Red", "Green" and "Blue".

By default, the first option will be selected. But I called the setSelectedIndex -1 to removed the selection. If you open the drop-down list, you see messages 1 and 2. Share this: Twitter Facebook.
