Scroll Bar with Manipulation Gesture

bulgogi

Hi all,

I wish to duplicate the scroll bar in the HoloLens Main Menu. Is there existing code I can reference or is this something I need to write from scratch. I didn't see any in the HoloToolKit.

I know I can register for the following events:

public event ManipulationCompletedEventDelegate ManipulationCompletedEvent;
public event ManipulationStartedEventDelegate ManipulationStartedEvent;

which returns a Ray that lets you know the direction of the manipulation. However, I'm not sure how to target the Scroll Rect component to do the actually scrolling. Any help is greatly appreciated!

Might want to use Gestures instead and subscribe to Navigation events.

            // Create a new GestureRecognizer. 
            // Sign up for manipulation events.
            manipulationRecognizer = new GestureRecognizer();

            manipulationRecognizer.NavigationStartedEvent += ManipulationRecognizer_NavigationStartedEvent;
            manipulationRecognizer.NavigationUpdatedEvent += ManipulationRecognizer_NavigationUpdatedEvent;
            manipulationRecognizer.NavigationCompletedEvent += ManipulationRecognizer_NavigationCompletedEvent;
            manipulationRecognizer.NavigationCanceledEvent += ManipulationRecognizer_NavigationCanceledvent;
