方法: メニューのマージと ToolStrip コントロールを使用して MDI フォームを作成する

[アーティクル]
05/04/2023

System.Windows.Forms 名前空間は、マルチドキュメントインターフェイス (MDI) アプリケーションをサポートし、MenuStrip コントロールはメニューの結合をサポートします。 MDI フォームは、ToolStrip コントロールもサポートします。

Visual Studio では、この機能に対する広範なサポートが用意されています。

「チュートリアル: メニューのマージと ToolStrip コントロールのある MDI フォームを作成する」も参照してください。

例

次のコード例は、ToolStripPanel コントロールを MDI フォームで使用する方法を示します。フォームは、子メニューをマージするメニューもサポートしています。
