Examples

[C#]

This C# example reports gesture information in a status bar and displays the hot point coordinates in the status bar.

using System;
using System.Drawing;
using System.Windows.Forms;
using Microsoft.Ink;

public class CSGestureForm : System.Windows.Forms.Form
{
    private System.Windows.Forms.StatusBar theGestureStatusBar;
    private InkCollector theInkCollector;
    private Point theHotPoint;

    public CSGestureForm()
    {
        // Initialize the form with a status bar at the bottom.
        theGestureStatusBar = new System.Windows.Forms.StatusBar();
        SuspendLayout();
        theGestureStatusBar.Location = new System.Drawing.Point(0, 244);

        Controls.AddRange(new System.Windows.Forms.Control[] {this. theGestureStatusBar});
        Text = "Gesture Test Application";
        this.BackColor = Color.LightGray;

        // Give the hot spot an initial value.
        theHotSpot = new Point(-1, -1);

        // Initialize the InkCollector object.

        theInkCollector.CollectionMode = CollectionMode.GestureOnly;

    }

    }

    private void Gesture_Event(object sender, InkCollectorGestureEventArgs e)
    {
        // Only get information on the first gesture returned.
        Gesture theGesture = e.Gestures[0];
        // Save the hot point information for painting.
        theHotPoint = theGesture.HotPoint;
        // Write the gesture type and confidence on the status bar.
        theGestureStatusBar.Text = theGesture.Id + "  " + theGesture.Confidence +
            ";  HotPoint coordinates:  " + theHotPoint.ToString();
        Refresh();
    }
