Gewusst wie: Erstellen eines MDI-Formulars mit ToolStripPanel-Steuerelementen
Aktualisiert: November 2007
Sie können ein MDI-(Multiple Document Interface-)Formular erstellen, das von vier ToolStrip-Steuerelementen (eines an jeder Seite) umgeben ist.
Beispiel
Das folgende Codebeispiel veranschaulicht die Verwendung angedockter ToolStripPanel-Steuerelemente, um ein MDI-Fenster mit vier ToolStrip-Steuerelementen zu umgeben.
Im Beispiel fügt die Join-Methode den ToolStrip-Steuerelementen die entsprechenden ToolStripPanel-Steuerelemente hinzu.
