Esempio

L'esempio di codice seguente è un semplice programma che applica stili di visualizzazione in ognuna delle quattro aree specificate dai VisualStyleState valori. Per abilitare gli stili visivi in un'area specifica, fare clic sul pulsante di opzione (noto anche come pulsante di opzione) che rappresenta l'area che si vuole abilitare e fare clic sul pulsante Update VisualStyleState per osservare le modifiche nella finestra.
