示例1: CreateGeometry

var padding = isMultiLine ? LineMarkerPadding : TextMarkerPadding;
var pos = span.Start;
PathGeometry geo = null;

var line = textView.GetTextViewLineContainingBufferPosition(pos.Position);
bool useVspaces = line.IsLastDocumentLine();
var lineExtent = new VirtualSnapshotSpan(new VirtualSnapshotPoint(line.Start), new VirtualSnapshotPoint(line.EndIncludingLineBreak, useVspaces ? span.End.VirtualSpaces : 0));
var extentTmp = lineExtent.Intersection(new VirtualSnapshotSpan(pos, span.End));
Debug.Assert(extentTmp != null);
if (line.VisibilityState != VisibilityState.Unattached && extentTmp != null && extentTmp.Value.Length != 0) {

private void SetDialogPosition(IWpfTextView _view, QuickLookDialog dialog)
{
SnapshotSpan span = _view.Selection.SelectedSpans[0];
var textViewOrigin = (_view as System.Windows.UIElement).PointToScreen(new Point(0, 0));
var caretPos = _view.Selection.Start.Position;
var charBounds = _view
.GetTextViewLineContainingBufferPosition(caretPos)
.GetCharacterBounds(caretPos);
double textBottom = charBounds.Bottom;
double textX = charBounds.Left;
double newLeft = textViewOrigin.X + textX - _view.ViewportLeft;
double newTop = textViewOrigin.Y + textBottom - _view.ViewportTop;
dialog.Left = newLeft;
dialog.Top = newTop;
