Class TimeChooserPanel

java.lang.Object
  org.eclipse.swt.widgets.Widget
      org.eclipse.swt.widgets.Control
          org.eclipse.swt.widgets.Scrollable
              org.eclipse.swt.widgets.Composite
                  de.jaret.util.ui.datechooser.TimeChooserPanel

All Implemented Interfaces:

java.util.EventListener, org.eclipse.swt.events.MouseListener, org.eclipse.swt.graphics.Drawable, org.eclipse.swt.internal.SWTEventListener

public class TimeChooserPanel
extends org.eclipse.swt.widgets.Composite
implements org.eclipse.swt.events.MouseListener

The TimeChooserPanel is intended to be used as a dropdown for the TimeFieldCombo (@see de.jaret.swt.util.datechooser.TimeChooser). However if it seems useful it is possible to be used as a standalone control for selecting a time.

Time is represented as the time part of a java.util.Date.
