IDesignerGlyphProvider Interface
Assembly: System.Workflow.ComponentModel (in system.workflow.componentmodel.dll)
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()); else glyphList.Add(new ExecutingGlyph()); } } return glyphList; } }
