Values
- traditional → const NavigationMode
-
This indicates a traditional keyboard-and-mouse navigation modality.
This navigation mode is where the arrow keys can be used for secondary modification operations, like moving sliders or cursors, and disabled controls will lose focus and not be traversable.
NavigationMode() - directional → const NavigationMode
-
This indicates a directional-based navigation mode.
This navigation mode indicates that arrow keys should be reserved for navigation operations, and secondary modifications operations, like moving sliders or cursors, will use alternative bindings or be disabled.
Some behaviors are also affected by this mode. For instance, disabled controls will retain focus when disabled, and will be able to receive focus (although they remain disabled) when traversed.
