Poznámky

Pomocí členů tohoto výčtu nastavte hodnotu Style vlastnosti StatusBarPanel třídy. Vlastnost Style určuje způsob, StatusBarPanel jakým se bude zobrazovat. StatusBarPanel objekty mohou zobrazit jednoduchý text nebo být nakresleny vlastníkem. Objekty nakreslené StatusBarPanel vlastníkem podporují zobrazení obrázků nebo jiného písma než ostatní StatusBarPanel objekty ovládacího prvku, zatímco objekty nakreslené StatusBarPanelStatusBar systémem slouží k zobrazení pouze textu (nebo textu a ikony, pokud je ikona zadána ve Icon vlastnosti StatusBarPanel). Chcete-li provést operace kreslení vlastníka nakreslený StatusBarPanelvlastníkem , použijte DrawItem událost StatusBar ovládacího prvku.
