Examples

The following code example demonstrates how you can implement the IDesignerGlyphProvider interface. It shows how you can implement the GetGlyphs method to draw custom glyph objects on an activity designer surface.

This code example is part of the Workflow Monitor SDK Sample from the DesignerGlyphProvider.cs file. For more information, see Workflow Monitor.

//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

Remarks

This interface defines the method that implementing classes must use to provide an appropriate set of DesignerGlyph objects to activity designers. The implementing class should also render the DesignerGlyph objects onto the ActivityDesigner object.
