IFocusManager
implementation. This focus
manager is designed to work on both desktop and mobile. Focus may be
controlled by Keyboard.TAB
(including going
backwards when holding the shift key) or with the arrow keys on a d-pad
(such as those that appear on a smart TV remote control and some game
controllers).
To simulate KeyLocation.D_PAD
in the AIR Debug
Launcher on desktop for debugging purposes, set
DeviceCapabilities.simulateDPad
to true
.
