public class PComboBox
extends javax.swing.JComboBox
implements java.io.Serializable

The PComboBox is used instead of a JComboBox in a Piccolo scene graph. This PComboBox won't work properly if it is located in an abnormal hierarchy of Cameras. Support is provided for only one (or zero) view transforms.

A ComboBox for use in Piccolo. This still has an associated JPopupMenu (which is always potentially heavyweight depending on component location relative to containing window borders.) However, this ComboBox places the PopupMenu component of the ComboBox in the appropriate position relative to the permanent part of the ComboBox. The PopupMenu is never transformed.

This class was not designed for subclassing. If different behavior is required, it seems more appropriate to subclass JComboBox directly using this class as a model.

NOTE: There is currently a known bug, namely, if the ComboBox receives focus through 'tab' focus traversal and the keyboard is used to interact with the ComboBox, there may be unexpected results.

Warning: Serialized objects of this class will not be compatible with future Piccolo releases. The current serialization support is appropriate for short term storage or RMI between applications running the same version of Piccolo. A future release of Piccolo will provide support for long term persistence.
