Stylus.PreviewStylusInRange Attached Event

Definition

Namespace:

System.Windows.Input

Assembly:

PresentationCore.dll

Occurs when the stylus comes within range of the tablet.

C#

see AddPreviewStylusInRangeHandler, and RemovePreviewStylusInRangeHandler

Examples

The following example demonstrates how to determine whether the stylus is inverted. This example assumes that there is a TextBox called textBox1 and that the PreviewStylusInRange event is connected to the event handlers.

C#

void textbox1_PreviewStylusInRange(object sender, StylusEventArgs e)
{
    if (e.StylusDevice.Inverted)
    {
        textbox1.AppendText("Pen is inverted\n");
    }
    else
    {
        textbox1.AppendText("Pen is not inverted\n");
    }
}

Remarks

This is an attached event. WPF implements attached events as routed events. An attached event is, fundamentally, a XAML language concept used to reference events that are handled on objects that do not, themselves, define events. WPF further expands an attached event's capabilities, allowing it to traverse a route. Attached events do not have a direct handling syntax in code; to attach handlers for a routed event in code, use a designated Add*Handler method. For details, see Attached Events Overview.
