I've tried to fashion a Calendar combo by using the CalendarCombo widget from Nebula (http://www.eclipse.org/nebula/widgets/calendarcombo/calendarcombo.php). My label provider follows:

public class MyCalendarLabelProvider extends ColumnLabelProvider {

private static final String CALENDAR_KEY = "CALENDAR_KEY";

public MyCalendarLabelProvider(ColumnViewer viewer) {

JFaceResources.getImageRegistry().put(CALENDAR_KEY, makeShot(viewer.getControl().getShell(), Calendar.getInstance()));

}

private Image makeShot(Shell shell, Calendar now)
{

Shell s = new Shell(shell, SWT.NO_TRIM);


CalendarCombo cCombo = new CalendarCombo(s, SWT.READ_ONLY);

cCombo.setDate(now);

Point cComboSize = cCombo.computeSize(SWT.DEFAULT, SWT.DEFAULT);

cCombo.setSize(cComboSize);

cCombo.setLocation(0, 0);

s.setSize(cComboSize);

s.open();

GC gc = new GC(cCombo);

Image image = new Image(shell.getDisplay(), cComboSize.x, cComboSize.y);

gc.copyArea(image, 0, 0);

gc.dispose();

s.close();

return image;

}

In order to compile, I must point to the .jar file named org.eclipse.nebula.widgets.calendarcombo_1.0.0.jar that came w/ the calendar. To do this from the Workbench, I choose Properties->Build Path->Add External Jars. Then I can compile. However, I get runtime errors as follows:

Error creating the view.
org/eclipse/nebula/widgets/calendarcombo/CalendarCombo

Am I including the JARs incorrectly? How can I remedy this?
