To find which widget has focus, I don't know whether you have solution already. As a novice to GWT , I propose my solution to share:

1. Declare private field in the object, like 'focusedWidget'

2. Create focus handler for the widget, here's class TextBox. In OnFocus block, just assign the widget to 'focusedWidget'. You can add this kind of event to every widget that can be focused. ![step 2][2]

3. That's all. Every widget you tied the focus event will set itself to 'focusedWidget' everytime it is focused. We can then use 'focusedWidget' to determind which current widget is focused. ![step 3][3]

I test it in JUnit, it works! see image of snippet here Hope that help.
