How to set viewport for multiple sticky note?

Hi everyone

I have to set the viewport for multiple widgets.

As you can see on this video, when I click the button, the board viewport have to change.

Well it works on SDK 1.1 now.

I used this code for get left, top, right and bottom value.

But on SDK 2.0, the left, top, right, bottom parameter is no longer available.

Please let me know how can I fix this issue.

Thank you
