示例1: Draw
public void Draw(TextView textView, DrawingContext drawingContext)
{
if (_segments == null)
return;
lock (_segments)
{
foreach (var segment in _segments)
{
var startLine = textView.GetVisualLine(segment.StartLineNumber);
var endLine = textView.GetVisualLine(segment.EndLineNumber);
// Make sure that startLine is valid (in view) since that is where we'll start to render
// the background. In case endLine is null, that means that we're outside of the view and
// should render the background to the last visible line.
if (startLine == null)
continue;
if (endLine == null)
endLine = textView.VisualLines.Last();
var y = startLine.GetTextLineVisualYPosition(startLine.TextLines[0], VisualYPosition.LineTop) - _textView.ScrollOffset.Y;
var yEnd = endLine.GetTextLineVisualYPosition(endLine.TextLines[0], VisualYPosition.LineBottom) - _textView.ScrollOffset.Y;
var rect = new System.Windows.Rect(0, y, textView.ActualWidth, yEnd - y);
drawingContext.DrawRectangle(_hightlightBrush, null, rect);
