Exemples
L’exemple de code suivant illustre l’utilisation des PictureBox contrôles et ListView . Le PictureBox est initialisé en définissant les BorderStyle propriétés et SizeMode à l’aide BorderStyle des énumérations et PictureBoxSizeMode , respectivement. le ListView est rempli avec les images du répertoire Sample Pictures. La ListView.GetItemAt méthode est utilisée dans lors de la gestion de l’événement MouseDown du ListView contrôle pour déterminer si un élément est sélectionné. Si un élément est sélectionné, le gestionnaire d’événements affiche le fichier sélectionné en définissant la Image propriété . L’exemple nécessite que vous disposiez de fichiers JPG situés dans le répertoire C:\Documents and Settings\All Users\Documents\My Pictures\Sample Pictures. Pour exécuter cet exemple, collez le code dans un formulaire et appelez les InitializePictureBox
méthodes et PopulateListView
dans le constructeur ou Load la méthode de gestion des événements du formulaire. Vérifiez que tous les événements sont associés à leurs méthodes de gestion des événements.
