Hi Steve

My main class extends org.eclipse.jface.window.ApplicationWindow which 
accepts a shell parameter in its constructor and doesn't give me much 
control in terms of taskbar. Here is the code snippet...

public class BaseJFace extends ApplicationWindow {

   public static void main(String[] args) {
       final Display display = Display.getDefault();
       shell = new Shell(display);
       // I can add the TrayItem code here....
       BaseJFace baseJFace = new BaseJFace(shell);
       baseJFace.setBlockOnOpen(true);
       baseJFace.open();
       display.dispose();
   }

   public BaseJFace(Shell shell) {
       super(shell);
   }

.
.
.
}

However if I do something like this

		Display display = new Display();

		Image large = new Image(display, 32, 32);

		gc = new GC(large);
		gc.setBackground(display.getSystemColor(SWT.COLOR_RED));
		gc.fillArc(0, 0, 32, 32, 45, 270);
		gc.dispose();


		Shell shell = new Shell(display);
		shell.setText("Large icons");
		shell.setImages(new Image[] {large});


		shell.open();
		while (!shell.isDisposed()) {
			if (!display.readAndDispatch())
				display.sleep();
		}

I can see the shell in taskbar, the key difference here is shell.open(). 

So my understanding is that the ApplicationWindow creates a new instance 
of shell somewhere and since the parent shell was never opened, it doesn't 
show up in the taskbar.

Lemme know yor thoughts...
