IDesignerGlyphProvider Interface

Note: This API is now obsolete.

Defines the method that glyph provider classes use to generate an array of glyphs to display on an activity designer.

Namespace:  System.Workflow.ComponentModel.Design
Assembly:  System.Workflow.ComponentModel (in System.Workflow.ComponentModel.dll)
[ObsoleteAttribute("The System.Workflow.* types are deprecated.  Instead, please use the new types from System.Activities.*")]
public interface IDesignerGlyphProvider

The IDesignerGlyphProvider type exposes the following members.

Public methodGetGlyphsReturns an array of glyphs that are associated with the specified activity designer.

This material discusses types and namespaces that are obsolete. For more information, see Deprecated Types in Windows Workflow Foundation 4.5.

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.

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());
                    glyphList.Add(new ExecutingGlyph());

        return glyphList;
