There was a post a while back about creating a window that was slightly transparent and overlays the ribbon. The purpose of this was to create a clock application (I think?) that sits on top of the homescreen for easy reference.

I posted a solution in a completely unrelated thread but this should probably be in separate thread (the original one was closed).

Here's the code:

class FloatingScreenMain extends UiApplication {
    
    public static void main( String[] args ) {
        FloatingScreenMain app = new FloatingScreenMain();
        app.enterEventDispatcher();
    }
    
    FloatingScreenMain() {    
    
        /**
         * Putting this on the event stack instead of pushing a screen from main 
         * ensures that the backbuffer is not cleared and that the main ribbon
         * continues to repaint.
         */
        UiApplication.getUiApplication().invokeLater( new Runnable() {
            public void run() {
                CustomPopupScreen popup = new CustomPopupScreen();
                pushScreen( popup );
            }
        });
    }
} 


class CustomPopupScreen extends Screen {
    
    private final static int _CUSTOM_SIZE   = 100;
    private final static int _ALPHA         = 0xBF; // 75% alpha
    private final static int _X             = ( Display.getWidth() - _CUSTOM_SIZE ) >> 1;
    private final static int _Y             = ( Display.getHeight() - _CUSTOM_SIZE ) >> 1; 
    
    
    CustomPopupScreen() {    
        super( new VerticalFieldManager( Manager.NO_VERTICAL_SCROLL | Manager.NO_VERTICAL_SCROLLBAR ) );
        add( new LabelField( "Floating Popup" ) );
    }
    
    protected void sublayout( int width, int height ) {
        setExtent( _CUSTOM_SIZE, _CUSTOM_SIZE );
        setPosition( _X, _Y );
        layoutDelegate( _CUSTOM_SIZE, _CUSTOM_SIZE );
    }
    
    protected void paintBackground( Graphics g ) {
        XYRect myExtent = getExtent();
        int color = g.getColor();
        int alpha = g.getGlobalAlpha();
        g.setGlobalAlpha( _ALPHA );
        g.setColor( 0xE3E3E3 );
        g.fillRect( 0, 0, myExtent.width, myExtent.height );
        g.setColor( color );
        g.setGlobalAlpha( alpha );
    }
    
    protected boolean keyDown( int keycode, int status ) {
        if ( Keypad.key( keycode ) == Keypad.KEY_ESCAPE ) {
            close();
            return true;
        }
        return super.keyDown( keycode, status );
    }
        
    
    
}
