Esempio

Nell'esempio di codice seguente viene mostrato come sia possibile implementare il metodo GetGlyphs per disegnare oggetti icone personalizzati in una superficie dell'ActivityDesigner.

Questo esempio di codice è parte dell'esempio SDK Workflow Monitor nel file DesignerGlyphProvider.cs. Per altre informazioni, vedere Monitoraggio del flusso di lavoro.
