示例1: OnStylusDown
// Prepare to collect stylus packets. Get the
// IncrementalHitTester from the InkPresenter's
// StrokeCollection and subscribe to its StrokeHitChanged event.
protected override void OnStylusDown(StylusDownEventArgs e)
{
base.OnStylusDown(e);
EllipseStylusShape eraserTip = new EllipseStylusShape(3, 3, 0);
eraseTester =
presenter.Strokes.GetIncrementalStrokeHitTester(eraserTip);
eraseTester.StrokeHit += new StrokeHitEventHandler(eraseTester_StrokeHit);
eraseTester.AddPoints(e.GetStylusPoints(this));
}
// Collect the StylusPackets as the stylus moves.
protected override void OnStylusMove(StylusEventArgs e)
{
if (eraseTester.IsValid)
{
eraseTester.AddPoints(e.GetStylusPoints(this));
}
}
// Unsubscribe from the StrokeHitChanged event when the
// user lifts the stylus.
protected override void OnStylusUp(StylusEventArgs e)
{
eraseTester.AddPoints(e.GetStylusPoints(this));
eraseTester.StrokeHit -= new
StrokeHitEventHandler(eraseTester_StrokeHit);
eraseTester.EndHitTesting();
}
// When the stylus intersects a stroke, erase that part of
// the stroke. When the stylus dissects a stoke, the
// Stroke.Erase method returns a StrokeCollection that contains
// the two new strokes.
void eraseTester_StrokeHit(object sender,
StrokeHitEventArgs args)
{
StrokeCollection eraseResult =
args.GetPointEraseResults();
StrokeCollection strokesToReplace = new StrokeCollection();
strokesToReplace.Add(args.HitStroke);
// Replace the old stroke with the new one.
if (eraseResult.Count > 0)
{
presenter.Strokes.Replace(strokesToReplace, eraseResult);
}
else
