デザイナから呼び出すことができる動詞を表します。

名前空間: System.ComponentModel.Design
アセンブリ: System (system.dll 内)
構文

Visual Basic (宣言)

<ComVisibleAttribute(True)> _
Public Class DesignerVerb
    Inherits MenuCommand

Visual Basic (使用法)

Dim instance As DesignerVerb

C#

[ComVisibleAttribute(true)] 
public class DesignerVerb : MenuCommand

C++

[ComVisibleAttribute(true)] 
public ref class DesignerVerb : public
 MenuCommand

J#

/** @attribute ComVisibleAttribute(true) */ 
public class DesignerVerb extends MenuCommand

JScript

ComVisibleAttribute(true) 
public class DesignerVerb extends
 MenuCommand

解説

デザイナ動詞とは、イベント ハンドラにリンクされているメニュー コマンドのことです。デザイナ動詞は、デザイン時にコンポーネントのショートカット メニューに追加されます。また、Visual Studio では、LinkLabel を使用して、[プロパティ] ウィンドウの [説明] ペインに各デザイナ動詞がリストされます。

メモ
このクラスに適用される HostProtectionAttribute 属性の Resources プロパティの値は、SharedState です。HostProtectionAttribute は、デスクトップ アプリケーション (一般的には、アイコンをダブルクリック、コマンドを入力、またはブラウザに URL を入力して起動するアプリケーション) には影響しません。詳細については、HostProtectionAttribute クラスのトピックまたは「SQL Server プログラミングとホスト保護属性」を参照してください。

使用例

DesignerVerb オブジェクトを作成し、コンポーネントのデザイン時ショートカット メニューに追加するコード例を次に示します。

Visual Basic

Imports System.ComponentModel
Imports System.Collections
Imports System.ComponentModel.Design

'  This sample demonstrates a designer that adds menu commands
'   to the design-time shortcut menu for a component.
'
'   To test this sample, build the code for the component as a class
 library, 
'   add the resulting component to the toolbox, open a form in design
 mode, 
'   and drag the component from the toolbox onto the form. 
'
'   The component should appear in the component tray beneath the form.
 
'   Right-click the component.  The verbs should appear in the shortcut
 menu.
