LWUIT Painter : How to draw a line on top of a Image Label?

Question

I have an image label created like this.

Painter painter = new Painter() 
        {

            public void paint(Graphics g, Rectangle rctngl) 
            {
                g.setColor(0x000000);
                g.drawLine(0, 0, 100, 100);
            }
        };
        mapScreen = new Form("Map");
        try 
        {
            Image image = Image.createImage("/res/Sample.jpg");
            Label labelImage = new Label(image);
            labelImage.setScrollVisible(true);
            labelImage.setFocus(true);
            labelImage.getStyle().setBgPainter(painter);
            mapScreen.addComponent(labelImage);

I want to draw some lines on top of it. I have tried using painter like the code above but I was not able to do it successfully. How am I doing wrong and how can I fix it?

EDIT:

The drawing of the lines is successful but the problem is that the lines are drawn behind the labelImage. How can I make it so that the lines will be drawn infront?

Answer 1

You need to apply the painter to Unselected and Selected style since you give the label focus. You are also drawing a diagonal line not a strait line.
