Stylus.PreviewStylusInRange Attached Event
Occurs when the stylus comes within range of the tablet.
Assembly: PresentationCore (in PresentationCore.dll)
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.
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 event is connected to the event handlers.
Private Sub textbox1_PreviewStylusInRange(ByVal sender As Object, _ ByVal e As StylusEventArgs) Handles textbox1.PreviewStylusInRange If e.StylusDevice.Inverted Then textbox1.AppendText("Pen is inverted" & vbLf) Else textbox1.AppendText("Pen is not inverted" & vbLf) End If End Sub 'textbox1_PreviewStylusInRange
