Parametri

Restituisce

Matrice di oggetti DesignerGlyph di cui eseguire il rendering sull'ActivityDesigner.

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.

    {
        this.activityStatusList = activityStatusList;
    }

    ActivityDesignerGlyphCollection IDesignerGlyphProvider.GetGlyphs(ActivityDesigner activityDesigner)
    {
        ActivityDesignerGlyphCollection glyphList = new ActivityDesignerGlyphCollection();

        //Walk all of the activities and use the 'CompletedGlyph' for all activities that are not 'closed'
