Stylus.StylusUp Attached Event

 

Occurs when the user raises the stylus from the Tablet PC.

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

See AddStylusUpHandler, RemoveStylusUpHandler

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 record the coordinates of the stylus, even if the stylus leaves the bounds of a TextBox. This example assumes that there is a TextBox called textBox1, and that the StylusDown, StylusUp, and StylusMove events are connected to event handlers.

void textbox1_StylusDown(object sender, StylusDownEventArgs e)
{
    Stylus.Capture(textbox1);
}

void textbox1_StylusMove(object sender, StylusEventArgs e)
{
    Point pos = e.GetPosition(textbox1);
    textbox1.AppendText("X: " + pos.X + " Y: " + pos.Y + "\n");
}

void textbox1_StylusUp(object sender, StylusEventArgs e)
{
    Stylus.Capture(textbox1, CaptureMode.None);
}
