Vorgehensweise: Erstellen eines MDI-Formulars mit der Zusammenführungsfunktion für Menüs und ToolStrip-Steuerelemente

Der System.Windows.Forms-Namespace unterstützt MDI-Anwendungen (Multiple Document Interface, Schnittstelle für mehrere Dokumente), und das MenuStrip-Steuerelement unterstützt das Zusammenführen von Menüs. MDI-Formulare können auch ToolStrip-Steuerelemente enthalten.

Visual Studio bietet umfassende Unterstützung für dieses Feature.

Siehe auch Exemplarische Vorgehensweise: Erstellen eines MDI-Formulars mit der Zusammenführungsfunktion für Menüs und ToolStrip-Steuerelemente.

Beispiel

Im folgenden Codebeispiel wird veranschaulicht, wie Sie ToolStripPanel-Steuerelemente mit einem MDI-Formular verwenden können. Das Formular unterstützt auch Zusammenführen von Menüs mit untergeordneten Menüs.
