IDesignerGlyphProvider 接口

定义

命名空间:

System.Workflow.ComponentModel.Design

程序集:

System.Workflow.ComponentModel.dll

注意

The System.Workflow.* types are deprecated. Instead, please use the new types from System.Activities.*

定义标志符号提供程序类用于生成在活动设计器上显示的标志符号数组的方法。

public interface class IDesignerGlyphProvider

[System.Obsolete("The System.Workflow.* types are deprecated.  Instead, please use the new types from System.Activities.*")]
public interface IDesignerGlyphProvider

[<System.Obsolete("The System.Workflow.* types are deprecated.  Instead, please use the new types from System.Activities.*")>]
type IDesignerGlyphProvider = interface

Public Interface IDesignerGlyphProvider

属性

ObsoleteAttribute

示例

下面的代码示例演示如何实现 IDesignerGlyphProvider 接口。 本示例演示如何实现 GetGlyphs 方法，以便在活动设计器图面上绘制自定义标志符号对象。

此代码示例摘自工作流监视器 SDK 示例中的 DesignerGlyphProvider.cs 文件。 有关详细信息，请参阅 工作流监视器。

//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

注解

注意

本材料讨论的类型和命名空间已废弃不用。 有关详细信息，请参阅 Windows Workflow Foundation 4.5 中弃用的类型。

此接口定义了一个方法，实现类必须使用该方法，来为活动设计器提供一组适当的 DesignerGlyph 对象。 此外，实现类还应在 DesignerGlyph 对象上呈现 ActivityDesigner 对象。

方法

GetGlyphs(ActivityDesigner)

已过时. 返回与指定活动设计器关联的标志符号的数组。
