Esempio

Nell'esempio di codice seguente viene illustrato come sia possibile implementare l'interfaccia IDesignerGlyphProvider, nonché 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.

//Custom glyphprovider used to draw the monitor glyphs on the designer surface
internal class WorkflowMonitorDesignerGlyphProvider : IDesignerGlyphProvider
{
    private Dictionary<string, ActivityStatusInfo> activityStatusList;

    internal WorkflowMonitorDesignerGlyphProvider(Dictionary<string, ActivityStatusInfo> activityStatusList)
    {
        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'
        foreach (ActivityStatusInfo activityStatus in activityStatusList.Values)
        {
            if (activityStatus.Name == activityDesigner.Activity.QualifiedName)
            {
                if (activityStatus.Status == "Closed")
                    glyphList.Add(new CompletedGlyph());
                else
                    glyphList.Add(new ExecutingGlyph());
            }
        }

        return glyphList;
    }
}

                End If
            End If
        Next

        Return glyphList
    End Function
End Class

Commenti

Questa interfaccia definisce il metodo che devono utilizzare le classi di implementazione per fornire un set appropriato di oggetti DesignerGlyph agli ActivityDesigner. La classe di implementazione deve inoltre eseguire il rendering degli oggetti DesignerGlyph sull'oggetto ActivityDesigner.
