示例1: DrawErrorMarkers
void DrawErrorMarkers (MonoTextEditor editor, Cairo.Context g, LineMetrics metrics, double y)
{
uint curIndex = 0, byteIndex = 0;
var o = metrics.LineSegment.Offset;
foreach (var task in errors.Select (t => t.Task)) {
var column = (uint)(Math.Min (Math.Max (0, task.Column - 1), metrics.Layout.LineChars.Length));
var line = editor.GetLine (task.Line);
// skip possible white space locations
while (column < line.Length && char.IsWhiteSpace (editor.GetCharAt (line.Offset + (int)column))) {
column++;
}
if (column >= line.Length)
continue;
int index = (int)metrics.Layout.TranslateToUTF8Index (column, ref curIndex, ref byteIndex);
var pos = metrics.Layout.Layout.IndexToPos (index);
var co = o + task.Column - 1;
g.SetSourceColor (GetMarkerColor (false, metrics.SelectionStart <= co && co < metrics.SelectionEnd));
g.MoveTo (
metrics.TextRenderStartPosition + editor.TextViewMargin.TextStartPosition + pos.X / Pango.Scale.PangoScale,
y + editor.LineHeight - 3
);
g.RelLineTo (3, 3);
g.RelLineTo (-6, 0);
