StylusDevice.Inverted Property

Silverlight

Other Versions

Gets or sets a value that indicates whether the stylus is inverted.

Namespace: System.Windows.Input
Assembly: System.Windows (in System.Windows.dll)

Syntax

Copy

public bool Inverted { get; }

Property Value

Type: System.Boolean
true if the stylus is inverted; otherwise, false. The default is false.

Remarks

For mouse input that is used for ink support instead of a stylus, the Inverted value is always false.

Examples

The following code example simulates a stylus that can be used as a highlighter when it is inverted.

Copy


//A new stroke object MyStroke is created and is added to the StrokeCollection 
//object of the InkPresenter MyIP
private void MyIP_MouseLeftButtonDown(object sender, MouseEventArgs e)
{
    MyIP.CaptureMouse();
    StylusPointCollection MyStylusPointCollection = new StylusPointCollection();
    MyStylusPointCollection.Add(e.StylusDevice.GetStylusPoints(MyIP));
    MyStroke = new Stroke(MyStylusPointCollection);
    MyStroke.DrawingAttributes = CloneDrawingAttributes(MyDA,e);
    MyIP.Strokes.Add(MyStroke);
}


...


//Set DrawingAttributes based on the stylus status
private DrawingAttributes CloneDrawingAttributes(DrawingAttributes attributes, MouseEventArgs e)
{
    DrawingAttributes cloneAttribute = new DrawingAttributes();
    if (attributes == null)
        return attributes;

    //Stylus is inverted. So set drawing attributes for a highlighter
    if (e.StylusDevice.Inverted == true)
    {
        cloneAttribute.Width = 25;
        cloneAttribute.Height = 5;
        cloneAttribute.Color = Colors.Yellow;
        cloneAttribute.OutlineColor = Colors.Yellow;
        return cloneAttribute;
    }

    //Stylus is not inverted. So set the default drawing attribute.
    else
    {

        cloneAttribute.Color = attributes.Color;
        cloneAttribute.Height = attributes.Height;
        cloneAttribute.OutlineColor = attributes.OutlineColor;
        cloneAttribute.Width = attributes.Width;
        return cloneAttribute;
    }
}
