Guide pratique pour créer un formulaire MDI avec des contrôles ToolStripPanel

  • Article

Vous pouvez créer un formulaire MDI (Multi Document Interface) qui a des contrôles ToolStrip les encadrant sur les quatre côtés.

Exemple

L’exemple de code suivant montre comment utiliser des contrôles ToolStripPanel ancrés pour cadrer une fenêtre MDI avec quatre contrôles ToolStrip.

Dans l’exemple, la méthode Join attache les contrôles ToolStrip aux contrôles ToolStripPanel correspondants.
