NotifyIcon.ContextMenu プロパティ

2008-03-28

アイコンのショートカットメニューを取得または設定します。

Public Property ContextMenu As ContextMenu
[C#]
public ContextMenu ContextMenu {get; set;}
[C++]
public: __property ContextMenu* get_ContextMenu();public: __property void set_ContextMenu(ContextMenu*);
[JScript]
public function get ContextMenu() : ContextMenu;public function set ContextMenu(ContextMenu);

プロパティ値

アイコンの ContextMenu 。既定値は null 参照 (Visual Basic では Nothing) です。

解説

タスクバーの状態通知領域のアイコンを右クリックすると、コンテキストメニューが表示されます。ショートカットメニューは、ポップアップメニューとも呼びます。

使用例

[Visual Basic, C#, C++] NotifyIcon クラスを使用して、アプリケーションのアイコンを通知領域内に表示する例を次に示します。この例では、 Icon 、 ContextMenu 、 Text 、 Visible の各プロパティを設定して、 DoubleClick イベントを処理しています。 Exit 項目がある ContextMenu は、 NotifyIcon.ContextMenu プロパティに割り当てられ、ユーザーがアプリケーションを終了できるようにします。NotifyIcon. DoubleClick イベントが発生すると、アプリケーションのフォームは Form.Activate メソッドを呼び出すことによってアクティブになります。
