Scscreen.onDisplay(), and Screen.afterDisplay()?

In blackBerry Screen class ,there is a method onDisplay() to do something before showing the screen .

Code:

onDisplay
 

protected void onDisplay()
 

    Invoked when this screen is pushed onto the display stack.

now i want do something after a screen has been painted. just like afterDisplay() or afterPaint().

there is a way to do this? any help? thanks!

only after onObscured() method called(some screen, dialog or open the menu will cause this method be called), the onExposed() method has being called.

right now I use this:

Code:

protected void onDisplay() {

                super.onDisplay();

                getApplication().invokeLater(new Runnable() {
 

                        public void run() {

                                Dialog.alert("on dispaly method called!");

                                

                        }

                        

                });

        }

looks like, after the screen displayed , the alert is showing.

Depending on which version you're using, try onUiEngineAttached.
