Beispiele

Im folgenden Codebeispiel wird veranschaulicht, wie das ListView Kachelfeature verwendet wird. Im Beispiel zeigt die Kachelansicht Elemente an, die Bücher darstellen. Jedes Element wird als Kachel angezeigt, die ein Symbol eines Buchs, den Titel, den Autor und das Publikationsjahr enthält. Damit der Beispielcode funktioniert, müssen Sie eine Symboldatei namens Book.ico in dasselbe Verzeichnis wie das Beispiel einschließen. Um die Kachelansicht ohne Symbole anzuzeigen, kommentieren Sie die Zeilen, die sich auf das ImageList Objekt beziehen.
