WinTouch.NET

WinTouch.NET is a .NET library for handling Windows 7 Touch Gestures in a WinForms application.

It allows you to handle the following gestures,

  • Pan
  • Rotate
  • Zoom
  • Two Finger Tap
  • Press and Tap

For more information on Windows Gestures, see Windows Touch Gestures Overview on MSDN.

The library has the following features,

  • Fails gracefully on operating systems older than Windows 7
  • Compiled against .NET 2.0 for maximum compatibility
  • Allows you to subscribe to just the events that you are interested in.

Usage

  1. Add a reference to WinTouch.dll to your project.
  2. Create a GestureListener passing in the control you want to receive touch events for.
  3. Optionally pass in a collection of GestureConfig objects to the GestureListener constructor to specify which gestures you want it to capture events for. By default, it captures GestureConfigurationFlag.GC_ALLGESTURES.
  4. On the GestureListener object you created, subscribe to the gesture events that you are interested in. It supports Pan, PressAndTap, Rotate, TwoFingerTap and Zoom.

For a demo on how to use the library, see the Demo project on GitHub. Here is an example,

public partial class GestureControl : UserControl
{
    // Our touch listener
    private readonly GestureListener _gesture;

    // Size, location and rotation of the image
    private Point _location;
    private int _size;
    private double _rotation;

    // An image to draw
    private Image m_image;

    // Brushes
    private readonly Brush[] _backBrushes = { Brushes.White, Brushes.AntiqueWhite, Brushes.Bisque, Brushes.Wheat, Brushes.Bisque, Brushes.AntiqueWhite };
    private int _backBrush;

    public GestureControl()
