UI Navigation

Auto Navigation

Each UI Toolkit panel features a focus ring that determines the focus order of elements. You can learn more about this feature here:

Unity - Manual: Dispatch events

See: Focus ring and the tab order

The UI Framework allows you to disable unrelated interactable elements using the UIElementManager, enabling Unity's auto navigation to function without manual setup.

Change what element is focused next

To manually change which element is focused next, you can register a callback for the NavigationMoveEvent:

A.RegisterCallback <NavigationMoveEvent>(e =>
{
    switch(e.direction)
    {
        case NavigationMoveEvent.Direction.Up: U.Focus(); break;
        case NavigationMoveEvent.Direction.Down: D.Focus(); break;
        case NavigationMoveEvent.Direction.Left: L.Focus(); break;
        case NavigationMoveEvent.Direction.Right: R.Focus(); break;
    }
    e.PreventDefault();
});
