[Gvsig_english] Refresh functionnality

[Charlotte Declercq]

Hello,

I am looking in the code to add a refresh functionnality to gvsig desktop.
I have modified the paint method of MapControl (lib_FMap) here to add :


                    while(true){
                       Thread.sleep(2000);
                       this.paint();
                      
                        //commandRefresh();
                        //System.out.println("refresh");
                   }
                  

to refresh the map all 2 seconds.

I would like to refresh only one layer and not all the layers, is it 
possible to do that? If yes could someone guide me?
If I could have a developper contact it would be great, thanks.

Charlotte.

Here is the whole function :

 public void paint()
        {
            try
            {
                canceldraw.setCanceled(false);
                /* if (image == null)
                {
                    image = new BufferedImage(vp.getImageWidth(), 
vp.getImageHeight(),
                            BufferedImage.TYPE_INT_ARGB);
                    Graphics gTemp = image.createGraphics();
                    Color theBackColor = vp.getBackColor();
                    if (theBackColor == null)
                        gTemp.setColor(Color.WHITE);
                    else
                        gTemp.setColor(theBackColor);

                    gTemp.fillRect(0,0,getWidth(), getHeight());
                    gTemp.dispose();
                    // g.drawImage(image,0,0,null);
                    System.out.println("Imagen con null en 
DESACTUALIZADO. Width = " + this.getWidth());
                } */
                Graphics2D g = image.createGraphics();

                ViewPort viewPort = mapContext.getViewPort();

                if (status == DESACTUALIZADO)
                {
                    Graphics2D gTemp = image.createGraphics();
                    Color theBackColor = viewPort.getBackColor();
                    if (theBackColor == null)
                        gTemp.setColor(Color.WHITE);
                    else
                        gTemp.setColor(theBackColor);
                    gTemp.fillRect(0, 0, viewPort.getImageWidth(), 
viewPort.getImageHeight());
                   
                   
                  // status = ACTUALIZADO;/****charlotte: décommenter
