Please help me on this Application

[Demith Waruna Samaraweera]

Currently I am developing a application to load an image of map and to show the mobile customers on the map using GPS coordinates
I am using both J2SE and J2EE

The main problem with me is i am adding a JLabel into JScrollPane and load the image to the JLabel, using the ImageIcon

The problems are

1 When I am zooming the image the ScrollBars does not adjust accordingly
2 I cant set the origin of the ZoomLabel as my wish it always set to 0,0
3 I cant add the user defined coordinates to the image(GPS of Maps) and to devide them when the mouse move

Thnk you

Sounds like you are doing some custom painting that requires more flexibility than JLabel was designed for. You could try making a custom graphics component

class MyGraphicsComponent extends JPanel
{
    ...
    protected void paintComponent(Graphics g)
    {
        // custom painting code goes here
        // you can specify the x, y location to paint your images
        // and use a zoom factor to zoom in and out
        // you can draw strings and graphics over the image
    }
 
    /**
     * this will tell the JScrollPane what it needs to be able to
     * properly display this component for each validation event
     */
    public Dimension getPreferredSize()
    {
        return new Dimension(desiredWidth, desiredHeight);
    }
}
