예제

다음 예제에서는 사용 하는 방법에 설명 합니다 GetDispatcher 렌더링 스레드에서 일부 작업을 수행 하는 방법입니다.

delegate void WorkerMethod();

class CustomDynamicRenderer : DynamicRenderer
{
    protected override void OnStylusDown(RawStylusInput rawStylusInput)
    {
        base.OnStylusDown(rawStylusInput);
        rawStylusInput.NotifyWhenProcessed(null);
    }

    protected override void OnStylusDownProcessed(object callbackData, bool targetVerified)
    {
        base.OnStylusDownProcessed(callbackData, targetVerified);

        Dispatcher renderingThreadDispatcher = this.GetDispatcher();
        renderingThreadDispatcher.BeginInvoke(DispatcherPriority.Normal, new WorkerMethod(DoSomething));
    }

    private void DoSomething()
    {
        // Perform work on the rendering thread.
    }
}

Delegate Sub WorkerMethod()

Class CustomDynamicRenderer
    Inherits DynamicRenderer

    Protected Overrides Sub OnStylusDown(ByVal rawStylusInput As RawStylusInput)

        MyBase.OnStylusDown(rawStylusInput)
        rawStylusInput.NotifyWhenProcessed(Nothing)

    End Sub


    Protected Overrides Sub OnStylusDownProcessed(ByVal callbackData As Object, ByVal targetVerified As Boolean)

        MyBase.OnStylusDownProcessed(callbackData, targetVerified)

        Dim renderingThreadDispatcher As Dispatcher = Me.GetDispatcher()
        renderingThreadDispatcher.BeginInvoke(DispatcherPriority.Normal, New WorkerMethod(AddressOf DoSomething))

    End Sub


    Private Sub DoSomething()
        ' Perform work on the rendering thread.
    End Sub

End Class
