[news.eclipse.platform.swt] Re: popup with checkboxes

[sgrey@xxxxxxxxx (Simon Grey)]

Thanks, Frank:

I tried the following piece of code. It seems popup menu is displayed with 
one 
menu item called "Menu Item", but no checkbox is displayed. What do we 
need to make checkbox to display? Thanks,

import org.eclipse.swt.SWT;
import org.eclipse.swt.widgets.Display;
import org.eclipse.swt.widgets.Event;
import org.eclipse.swt.widgets.Listener;
import org.eclipse.swt.widgets.Menu;
import org.eclipse.swt.widgets.MenuItem;
import org.eclipse.swt.widgets.Shell;

public class PopupMenuTest 
{
	public static void main (String [] args) {
		final Display display = new Display ();
		final Shell shell = new Shell (display);
		shell.addListener (SWT.MenuDetect, new Listener () {
			public void handleEvent (Event event) {
				Menu menu = new Menu (shell, SWT.POP_UP);
				MenuItem item = new MenuItem (menu, SWT.CHECK);
				item.setText ("Menu Item");
				item.addListener (SWT.Selection, new Listener () {
					public void handleEvent (Event e) {
						System.out.println ("Item Selected");
					}
				});
				menu.setLocation (event.x, event.y);
				menu.setVisible (true);
				while (!menu.isDisposed () && menu.isVisible ()) {
					if (!display.readAndDispatch ()) display.sleep ();
				}
				menu.dispose ();
			}
		});
		shell.pack ();
		shell.open ();
		while (!shell.isDisposed ()) {
			if (!display.readAndDispatch ()) display.sleep ();
		}
		display.dispose ();
	}
}
