I have a window inside a tabGroup that I'd like to be able to make full screen at the user's leisure. In a button click event I call window.hideTabBar() and window.hideNavBar(). The hideNavBar call works, but hideTabBar doesn't.
There is a ghetto workaround, which is setting the activeTab to another tab and then switching back to the current. It looks on in the emulator but horrible on the phone (you can see the tab switching).
The tabbar cannot be hidden if the window it's already displayed.
