TabScreen

Class Overview

The TabScreen class implements a specialized screen that manages a tab-style selection interface.

Cross Platform Considerations

In iOS, this screen interface displays tabs at the bottom of the window for selecting between the different modes and for displaying the views for that mode. If there is more than 5 tab item, then iOS will show a "More" tab item in order to show additional tab items into a separate list.

In Android, this screen interface displays tabs at the top of the window for selecting between the different modes and for displaying the views for that mode.

Navigation controller behaviors

In iOS and Android, each tab keeps a sub-navigation stack. To access to the stack of the TabScreen and replace or pop the TabScreen, use getRootController() on a controller instance.
For other platforms, if a tab content will push a screen, then the TabScreen will be saved into the stack, and the new screen will be displayed. To go back to the TabScreen, the user will click over Back button.

Image sizes

• iOS: 30 x 30 pixels (low resolutions) and 60 x 60 pixels (high resolutions)
• Android: 24 x 24 pixels (ldpi), 32 x 32 pixels (mdpi), 48 x 48 pixels (hdpi), 64 x 64 pixels (xhdpi)
