Nested class will not add fields to MainScreen

Hello,

 

I am trying to have a nested class access the UI event thread. The code in my nested class will run, but any "add(...)" will not update my MainScreen.

 

Is this not allowed? Thanks!

 

Here is my code:

 

 

public class HomeScreen extends MainScreen implements FieldChangeListener {

     public HomeScreen() {
          doAction();
     }


     public void doAction() {
new InnerClass();
 } class InnerClass extends MainScreen { public InnerClass() { UiApplication.getUiApplication().invokeLater(new Runnable() { public void run() { add(new SeparatorField()); } }); } } }

Re: Nested class will not add fields to MainScreen

Which screen is displayed?

 

Your inner class is adding the field to Innerclass, not HomeScreen.

Re: Nested class will not add fields to MainScreen

Ah I see, HomeScreen was being displayed. So what I did was change:

 

 

class MiddleGround extends MainScreen {}

 

 

to:

 

 

class MiddleGround {}

 

and it is working now. Thanks!
