Examples
The following example demonstrates how to set the EditingMode property of an InkCanvas to EraseByStroke when the stylus is inverted. This example assumes that there is an InkCanvas called inkCanvas1
and that the StylusInRange event is connected to the event handlers. To see the cursor change, set the UseCustomCursor property to true
on inkCanvas1
.
void inkCanvas1_StylusInRange(object sender, StylusEventArgs e)
{
if (e.StylusDevice.Inverted)
{
inkCanvas1.EditingMode = InkCanvasEditingMode.EraseByStroke;
inkCanvas1.Cursor = System.Windows.Input.Cursors.Hand;
}
else
{
inkCanvas1.EditingMode = InkCanvasEditingMode.Ink;
inkCanvas1.Cursor = System.Windows.Input.Cursors.Pen;
}
}
Private Sub inkCanvas1_StylusInRange(ByVal sender As Object, ByVal e As StylusEventArgs) _
Handles inkCanvas1.StylusInRange
If e.StylusDevice.Inverted = True Then
inkCanvas1.EditingMode = InkCanvasEditingMode.EraseByStroke
inkCanvas1.Cursor = System.Windows.Input.Cursors.Hand
Else
inkCanvas1.EditingMode = InkCanvasEditingMode.Ink
inkCanvas1.Cursor = System.Windows.Input.Cursors.Pen
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.
