The UI Style Guide for Series 80 says:
------------------------------------------------------
When Full Screen Mode is active, neither the Indicator Area nor the CBA are on the screen. Showing the title in Full Screen Mode is optional.
------------------------------------------------------
I want to know how to enable Full screen mode? In which my cba buttons will auto hide in such fashion.
e.g. like in Opera/ Web application of 9500 using C++.
i don't know whether there is a simple statement by which it would be able to switch to full screen mode...but you may do it using MakeVisible() function to hide Control Button Area/Array and Indicator Area. See SDK help for EikButtonGroupContainer and CEikStatusPane.
