The following example demonstrates how to determine whether the stylus is inverted. This example assumes there is a TextBox called textBox1 and that the PreviewStylusOutOfRange event is connected to the event handlers.
void textbox1_PreviewStylusOutOfRange(object sender, StylusEventArgs e)
{
if (e.StylusDevice.Inverted)
{
textbox1.AppendText("Pen is inverted\n");
}
else
{
textbox1.AppendText("Pen is not inverted\n");
}
}
Private Sub textbox1_PreviewStylusOutOfRange(ByVal sender As Object, _
ByVal e As StylusEventArgs) Handles textbox1.PreviewStylusOutOfRange
If e.StylusDevice.Inverted Then
textbox1.AppendText("Pen is inverted" & vbLf)
Else
textbox1.AppendText("Pen is not inverted" & vbLf)
End If
End Sub
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.
