Przykłady

W poniższym przykładzie kodu pokazano, jak można zaimplementować metodę GetGlyphs do rysowania niestandardowych obiektów glif na powierzchni projektanta działań.

Ten przykład kodu jest częścią przykładowego zestawu SDK monitora przepływu pracy z pliku DesignerGlyphProvider.cs. Aby uzyskać więcej informacji, zobacz Monitor przepływu pracy.
