Ejemplos

En el ejemplo de código siguiente se agrega una sombra a un ListBox mediante los siguientes miembros:The following code example adds a shadow to a ListBox by using the following members:

• Addition

• PointF.Addition

• SolidBrush

Este ejemplo está diseñado para usarse con un Windows Form.This example is designed to be used with a Windows Form. Para ejecutar este ejemplo, pegue este código en un formulario y llame al AddShadow método al controlar el evento del formulario Paint .To run this example, paste this code into a form and call the AddShadow method when handling the form's Paint event. Compruebe que el formulario contiene un ListBox denominado listBox1 .Verify that the form contains a ListBox named listBox1.
