Параметры

gesture
Тип: Microsoft.Ink.ApplicationGesture
A member of the ApplicationGesture enumeration that represents the gesture to query about.

Возвращаемое значение

Тип: System.Boolean
true if the InkCollector object has interest in a particular application gesture; otherwise, false.

Заметки

The Gesture event is raised when the gesture is recognized.

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

To set interest of the InkCollector object for a particular gesture, call the InkCollector.SetGestureStatus method.

Примечание.
By default, the InkCollector object does not have interest in any application gesture.

Примеры

This C# example creates an ArrayList that contains all application gestures for which an InkCollector object, theInkCollector, has interest.

using Microsoft.Ink;
// . . .
// Return an array of all of the ApplicationGestures that
// have their status set to true on the InkCollector object.
private ApplicationGesture [] GetSetAppGestures(InkCollector theInkCollector)
{
    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 && 
            theInkCollector.GetGestureStatus(theGesture))
        {
            result.Add(theGesture);
        }
    }
    return (ApplicationGesture[])result.ToArray(typeof(ApplicationGesture));
}

This Microsoft Visual Basic .NET example creates an ArrayList that contains all application gestures for which an InkCollector object, theInkCollector, has interest.

Imports Microsoft.Ink
' . . .
' Return an array of all of the ApplicationGestures that
' have their status set to true on the InkCollector object.
Private Function GetSetAppGestures(ByVal theInkCollector As InkCollector) As ApplicationGesture()
    Dim result As New ArrayList()
    Dim sampleGesture As ApplicationGesture = ApplicationGesture.NoGesture
    Dim theGestures As Array = System.Enum.GetValues(sampleGesture.GetType())
    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 _
            theInkCollector.GetGestureStatus(theGesture) Then
            result.Add(theGesture)
        End If
    Next
    Return CType(result.ToArray(test.GetType()), ApplicationGesture())
End Function
