Si los estilos visuales están habilitados en el sistema operativo y los estilos visuales se aplican a la aplicación actual, este método dibujará el botón con el estilo visual actual. De lo contrario, dibujará el botón con el estilo clásico de Windows.

Ejemplos

En el ejemplo de código siguiente se usa el DrawButton(Graphics, Rectangle, String, Font, Boolean, PushButtonState) método en el método de OnPaint un control personalizado para dibujar un botón en el estado determinado por la ubicación del puntero del mouse. Este ejemplo de código es parte de un ejemplo mayor proporcionado para la clase ButtonRenderer.
