Ejemplos

En el ejemplo de código siguiente se dibuja el cursor especificado en el formulario con su tamaño normal y, en modo ajustado, dos veces su tamaño.The following code example draws the specified cursor on the form in its normal size, and in stretched mode, twice its size. En este ejemplo requiere que haya un Form y un Cursor objeto que se va a pasar al método cuando se llama.This example requires that you have a Form and a Cursor object to pass into the method when it is called.

El comando de dibujo se origina en la superficie gráfica representada por el g parámetro, pero un Graphics no contiene información sobre cómo representar una imagen determinada, por lo que pasa la llamada a la Cursor.The drawing command originates on the graphics surface represented by the g parameter, but a Graphics does not contain information about how to render a given image, so it passes the call to the Cursor. El Draw método recorta la imagen a las dimensiones determinadas y le permite especificar un Rectangle dentro del cual se va a dibujar el Cursor.The Draw method crops the image to the given dimensions and allows you to specify a Rectangle within which to draw the Cursor. Normalmente se usa este método si desea que se va a dibujar el cursor en una superficie gráfica.This method is typically used if you want to draw the cursor on a Graphics surface. Por ejemplo, podría tener un cuadro de diálogo que permite al usuario seleccionar cursores desde un ListBox control o un grupo de RadioButton controles.For example, you might have a dialog that allows the user to select cursors from a ListBox control, or a group of RadioButton controls.
