Éditeur de boîtes de dialogue modales personnalisé pour la configuration d’adaptateurs
Le code de l’éditeur personnalisé montre un éditeur dérivé de la classe System.Drawing.Design.UITypeEditor qui affiche une boîte de dialogue contextuelle modale permettant d’entrer un mot de passe. Le remplacement de la méthode GetEditStyle renvoie UIEditorEditStyle.Modal pour indiquer un sous-contrôle de formulaire modal. La méthode de service ShowDialog gère le contrôle créé avec CreatePassword. ShowDialog retourne un DialogResult qui est géré de la manière habituelle (par exemple, une instruction switch) avec la valeur de changement de casse DialogResult.OK uniquement.
Le code suivant correspond à la définition de classe pour l'éditeur modal personnalisé :
