How to select a TabItem in a TabPanel programmatically

[gishmo]

I am looking for something similar in GXT 3.0 like selectTab in GWT.

I have a TabPanel with several tabs and I want to focus a tab depending on several criteria. In GXT 2.x I could do this with: tabPanel.setSelection(...).

How will I do this with GXT 3.0?

Thanks
