Příklady

Následující příklad kódu je jednoduchý program, který používá vizuální styly v každé ze čtyř oblastí určených VisualStyleState hodnotami. Pokud chcete povolit vizuální styly v určité oblasti, klikněte na tlačítko možnosti (označované také jako přepínač), které představuje oblast, kterou chcete povolit, a kliknutím na tlačítko Aktualizovat VisualStyleState sledujte změny v okně.
