Guide pratique pour définir le convertisseur ToolStrip pour une application

  • Article

Vous pouvez personnaliser l'apparence de vos contrôles ToolStrip individuellement ou pour tous les contrôles ToolStrip de votre application.

Exemple

L'exemple de code suivant montre comment appliquer de manière sélective un convertisseur personnalisé à un contrôle ToolStrip et à un contrôle MenuStrip.

Pour utiliser cet exemple de code, compilez et exécutez l'application, puis sélectionnez la portée du rendu personnalisé à partir du contrôle ComboBox. Cliquez sur Appliquer pour définir le convertisseur.

Pour afficher le rendu d’élément de menu personnalisé, sélectionnez l’option dans le ComboBox contrôle, cliquez sur Appliquer, puis ouvrez l’élément de menu Fichier.MenuStrip
