How to make Main Screen transparent in BlackBerry?

I want to create an application in which I want to get a dialog when some event occurs. I am able to get the Dialog but behind that I am getting a white screen. I don't want that screen. Is there any way to make that screen transparent?

public final class LoadingPopupScreen extends PopupScreen
{ Background background; HorizontalFieldManager hfm; int width; int height; public LoadingPopupScreen( int width, int height) { super(new VerticalFieldManager()); background = BackgroundFactory.createLinearGradientBackground(Color.ROYALBLUE, Color.BLACK, Color.ROYALBLUE, Color.BLACK); setBackground(background); add(new LabelField("ROAMING")); add(new SeparatorField()); add(new SeparatorField()); hfm = new HorizontalFieldManager(); Bitmap bitmap = Bitmap.getBitmapResource("splash.png"); BitmapField bit= new BitmapField(bitmap); hfm.add(bit); hfm.add(new LabelField("want to check In Roaming or not?")); add(hfm); hfm = new HorizontalFieldManager(Manager.FIELD_HCENTER); ButtonField ok = new ButtonField("OK", HorizontalFieldManager.FIELD_HCENTER); ButtonField cancel = new ButtonField("CANCEL", HorizontalFieldManager.FIELD_HCENTER); hfm.add(ok); hfm.add(cancel); add(hfm); }
}

i have done it using:

Ui.getUiEngine().pushGlobalScreen(new LoadingPopupScreen(300,300), 0, UiEngine.GLOBAL_QUEUE);
