示例1: OnMouseLeftButtonDown
protected override void OnMouseLeftButtonDown(MouseButtonEventArgs e)
{
base.OnMouseLeftButtonDown(e);
if (e.StylusDevice != null)
{
return;
}
EllipseStylusShape eraserTip = new EllipseStylusShape(3, 3, 0);
eraseTester =
presenter.Strokes.GetIncrementalStrokeHitTester(eraserTip);
eraseTester.StrokeHit += new StrokeHitEventHandler(eraseTester_StrokeHit);
eraseTester.AddPoint(e.GetPosition(this));
}
protected override void OnMouseMove(MouseEventArgs e)
{
base.OnMouseMove(e);
if (e.StylusDevice != null || eraseTester == null)
{
return;
}
if (eraseTester.IsValid)
{
eraseTester.AddPoint(e.GetPosition(this));
}
}
protected override void OnMouseLeftButtonUp(MouseButtonEventArgs e)
{
base.OnMouseLeftButtonUp(e);
if (e.StylusDevice != null)
{
return;
}
eraseTester.AddPoint(e.GetPosition(this));
eraseTester.StrokeHit -= new
StrokeHitEventHandler(eraseTester_StrokeHit);
eraseTester.EndHitTesting();
}示例2: eraseTester_StrokeHit
// 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
{
presenter.Strokes.Remove(strokesToReplace);
}
