ItemListener Interface

Package: java.awt

ItemListener is the interface that must be implemented by classes that will handle item events that are raised when the user selects an item in a list box or combo box control.

For more information, see ItemEvent Class.

Method

Method	Description
void itemStateChanged (ItemEvent e)	This method is invoked when an action is performed on a control with which this class is registered as an action event listener.

Here’s an example of a class that implements ItemListener:

private class MyItemListener

implements ItemListener

{

public void itemStateChanged(ItemEvent e)

{

// code to handle item event

}

}

To register this class with a list control named list1, use a statement like this:

list1.addItemListener(new MyItemListener());
