Hi All.,

Is it possible to display transparent background for paint...

For example:

I have to pushscreen for paint display... Currently it will create full screen for display..

i want that will happen in transparent background... It means,you launch your application

from your homescreen! that time paint will be painted as well home screen background

also you can view(whatever screen you have, paint display will be paint in transparent background)

How can i solve this problem...

i hope somebody can help me!!! Thanks

uiapplications always have a white background.
you will have to extend application and push a global screen using the Ui class. If you create this screen with a smaller size the homescreen will stay visible behind it.

Thanks For reply,

if i used globalscreen,same fullscreen view will be displayed..

Called globalscreen from another screen A:-

      1.UiApplication.getUiApplication().pushGlobalScreen(sObj,1,UiEngine.GLOBAL_MODAL);

Following code represent called Screen B:-

     2.

         public class ScreenB

            {

                   public void paint(Graphics g)
                   {

                      g.drawBitmap(0, 0, this.getWidth(), this.getHeight(),settings.getBackGround(), 0, 0);
                      g.setColor(Color.BLACK);
                      g.drawRoundRect(9, this.getHeight()/2-1, this.getWidth()-18, this.getHeight()/2-8,10,10);
                      g.setColor(Color.WHITE);
                      g.fillRoundRect(10,this.getHeight()/2,this.getWidth()-20,this.getHeight()/2-10,10,10);
                      g.setColor(settings.getColorTextTitle());
                      g.setFont(settings.getFontTitle());
                      g.drawText(sBannerValue[2],15,this.getHeight()/2+3);
                      g.drawLine(10,this.getHeight()/2+23,this.getWidth()-11,this.getHeight()/2+23);

                   }

            }

like this...

you are mentioned to develop smaller screen, in this paint how can i achieve?

Thanks again.

extend Application, not UiApplication.
given a horizontalfieldmanager hfm this pushes a popupscreen with overwritten escape-key to close it: 

Ui.getUiEngine().pushGlobalScreen(new PopupScreen(hfm) {
     protected boolean keyChar(char c, int status, int time) {
        if (c == Characters.ESCAPE) {
           System.exit(0);
        }
        return super.keyChar(c, status, time);
     }
}, 1, UiEngine.GLOBAL_QUEUE);
