[news.eclipse.platform.swt] Re: How to let Popup Shell show up at the gi

["Stuart Pond" <Stuart.Pond@xxxxxxx>]

How about trying the snippet that is on SWT snippet site.  Note they are 
using Display.getCursorLocation().

public class Snippet233 {
	public static void main (String [] args) {
		final Display display = new Display ();
		final Shell shell = new Shell (display);
		shell.setText ("Parent Shell");
		shell.addMouseListener (new MouseAdapter() {
			public void mouseDown (MouseEvent e) {
				Shell dialog = new Shell (shell, SWT.DIALOG_TRIM | 
SWT.APPLICATION_MODAL);
				Point pt = display.getCursorLocation ();
				dialog.setLocation (pt.x, pt.y);
				dialog.setText ("Dialog Shell");
				dialog.setSize (100, 100);
				dialog.open ();
			}});
		shell.setSize (400, 400);
		shell.open ();
		while (!shell.isDisposed ()) {
			if (!display.readAndDispatch ()) display.sleep ();
		}
		display.dispose ();
	}
}
