Return Value

System.Boolean. Whether the InkPicture control has interest in a particular application gesture.

true	The InkPicture control has interest in the gesture. The Gesture event is raised when the gesture is recognized.
false	The InkPicture control has no interest in the gesture.

Exceptions

COMException :
ObjectDisposedException : The InkPicture control is disposed.

Remarks

This method throws an exception if the gesture parameter is set to AllGestures.

To set interest of the InkPicture control for a particular gesture, call the InkPicture.SetGestureStatus method.

Note: By default, the InkPicture control does not have interest in any application gesture.

Examples

[C#]

This C# example creates an ArrayList that contains all application gestures for which an InkPicture control, theInkPicture, has interest.

using Microsoft.Ink;
// . . .
// Return an array of all of the ApplicationGestures that
// have their status set to true on the InkPicture control.
private ApplicationGesture [] GetSetAppGestures(InkPicture theInkPicture)
{
    ArrayList result = new ArrayList();
    Array gestureArray = System.Enum.GetValues(typeof(ApplicationGesture));
    foreach (ApplicationGesture theGesture in gestureArray)
    {
        // ApplicationGesture.AllGestures is not a meaningful
        // gesture to pass to GetGestureStatus()
        if (theGesture != ApplicationGesture.AllGestures &&
        theInkPicture.GetGestureStatus(theGesture))
        {
            result.Add(theGesture);
        }
    }
    return (ApplicationGesture[])result.ToArray(typeof(ApplicationGesture));
}

[VB.NET]

This Microsoft® Visual Basic® .NET example creates an ArrayList that contains all application gestures for which an InkPicture control, theInkPicture, has interest.

    Dim theGesture As ApplicationGesture
    For Each theGesture In theGestures
        ' ApplicationGesture.AllGestures is not a meaningful
        ' gesture to pass to GetGestureStatus()
        If (Not theGesture.Equals(ApplicationGesture.AllGestures)) AndAlso _
            theInkPicture.GetGestureStatus(theGesture) Then
            result.Add(theGesture)
        End If
    Next
    Return CType(result.ToArray(sampleGesture.GetType()), ApplicationGesture())
