IDesignerGlyphProvider 介面

定義

命名空間:

System.Workflow.ComponentModel.Design

組件:

System.Workflow.ComponentModel.dll

警告

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

定義圖像 (Glyph) 提供者類別用來產生圖像陣列的方法，讓這些圖像顯示在活動設計工具上。

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

屬性

ObsoleteAttribute

範例

下列程式碼範例示範如何實作 IDesignerGlyphProvider 介面。 它顯示如何實作 GetGlyphs 方法，在活動設計工具介面上繪製自訂圖像物件。

這個程式碼範例是 DesignerGlyphProvider.cs 檔案中＜工作流程監視器 SDK＞範例的一部分。 如需詳細資訊，請參閱 工作流程監視器。

//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;
    }
}

備註

注意

此資料討論已被汰換的類型及命名空間。 如需詳細資訊，請參閱 Windows Workflow Foundation 4.5 中即將淘汰的類型。

這個執行個體可定義方法，讓實作類別用於提供一組適合的 DesignerGlyph 物件給活動設計工具。 實作類別還應該在 DesignerGlyph 物件上呈現 ActivityDesigner 物件。

方法

GetGlyphs(ActivityDesigner)

已淘汰. 傳回與指定之活動設計工具關聯的圖像陣列。
