Comentarios

Cuando se establece la DrawMode propiedad en OwnerDrawFixed, el TabControl genera el DrawItem evento cada vez que necesita pintar una de sus pestañas.When you set the DrawMode property to OwnerDrawFixed, the TabControl raises the DrawItem event whenever it needs to paint one of its tabs. Para personalizar la apariencia de las pestañas, proporcione su propio código de dibujo en un controlador DrawItem para el evento.To customize the appearance of the tabs, provide your own painting code in a handler for the DrawItem event.

TabControl No admite tamaños de pestaña variables con dibujo de propietario.The TabControl does not support variable tab sizes with owner drawing.
