Ejemplos

En el ejemplo de código siguiente se muestra cómo implementar la interfaz IDesignerGlyphProvider. Muestra cómo puede implementar el método GetGlyphs para dibujar los objetos de glifo personalizados en una superficie del diseñador de actividad.

Este ejemplo de código forma parte del ejemplo SDK del monitor de flujo de trabajo del archivo DesignerGlyphProvider.cs. Para obtener más información, consulte Monitor de flujo de trabajo.

//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;
    }
}

'Custom glyphprovider used to draw the monitor glyphs on the designer surface
Friend Class WorkflowMonitorDesignerGlyphProvider
    Implements IDesignerGlyphProvider

    Dim activityStatusList As Dictionary(Of String, ActivityStatusInfo)

    Friend Sub New(ByVal activityStatusList As Dictionary(Of String, ActivityStatusInfo))
        Me.activityStatusList = activityStatusList
    End Sub
    Public Function GetGlyphs(ByVal activityDesigner As System.Workflow.ComponentModel.Design.ActivityDesigner) As System.Workflow.ComponentModel.Design.ActivityDesignerGlyphCollection Implements System.Workflow.ComponentModel.Design.IDesignerGlyphProvider.GetGlyphs
        Dim glyphList As ActivityDesignerGlyphCollection = New ActivityDesignerGlyphCollection()

        'Walk all of the activities and use the 'CompletedGlyph' for all activities that are not 'closed'
        For Each activityStatus As ActivityStatusInfo In activityStatusList.Values
            If activityStatus.Name = activityDesigner.Activity.Name Then
                If activityStatus.Status = "Closed" Then
                    glyphList.Add(New CompletedGlyph())
                Else
                    glyphList.Add(New ExecutingGlyph())
                End If
            End If
        Next

        Return glyphList
    End Function
End Class

Comentarios

Esta interfaz define el método que las clases de implementación deben utilizar para proporcionar un conjunto adecuado de objetos DesignerGlyph a los diseñadores de actividad. La clase de implementación también debería representar los objetos DesignerGlyph del objeto ActivityDesigner.
