IDesignerGlyphProvider.GetGlyphs(ActivityDesigner) 方法

定义

命名空间:

System.Workflow.ComponentModel.Design

程序集:

System.Workflow.ComponentModel.dll

返回与指定活动设计器关联的标志符号的数组。

public:
 System::Workflow::ComponentModel::Design::ActivityDesignerGlyphCollection ^ GetGlyphs(System::Workflow::ComponentModel::Design::ActivityDesigner ^ activityDesigner);

public System.Workflow.ComponentModel.Design.ActivityDesignerGlyphCollection GetGlyphs (System.Workflow.ComponentModel.Design.ActivityDesigner activityDesigner);

abstract member GetGlyphs : System.Workflow.ComponentModel.Design.ActivityDesigner -> System.Workflow.ComponentModel.Design.ActivityDesignerGlyphCollection

Public Function GetGlyphs (activityDesigner As ActivityDesigner) As ActivityDesignerGlyphCollection

参数

activityDesigner

ActivityDesigner

要检索其标志符号的 ActivityDesigner 对象。

返回

ActivityDesignerGlyphCollection

要在活动设计器上呈现的 DesignerGlyph 对象的数组。

示例

下面的代码示例演示如何实现 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。
