public class Choice
extends Component sample code for java.awt.Component definition code for java.awt.Component
implements ItemSelectable sample code for java.awt.ItemSelectable definition code for java.awt.ItemSelectable , Accessible sample code for javax.accessibility.Accessible definition code for javax.accessibility.Accessible

The Choice class presents a pop-up menu of choices. The current choice is displayed as the title of the menu.

The following code example produces a pop-up menu:


 Choice ColorChooser = new Choice();
 ColorChooser.add("Green");
 ColorChooser.add("Red");
 ColorChooser.add("Blue");
 

After this choice menu has been added to a panel, it appears as follows in its normal state:

The following text describes the graphic

In the picture, "Green" is the current choice. Pushing the mouse button down on the object causes a menu to appear with the current choice highlighted.

Some native platforms do not support arbitrary resizing of Choice components and the behavior of setSize()/getSize() is bound by such limitations. Native GUI Choice components' size are often bound by such attributes as font size and length of items contained within the Choice.

Since:
JDK1.0
