Ejemplos

En el ejemplo siguiente se muestran las WindowLeft propiedades,,,,, y, y WindowTop WindowWidth WindowHeight BufferWidth BufferHeight CursorVisible los SetWindowPosition SetBufferSize métodos, y ReadKey .The following example demonstrates the WindowLeft, WindowTop, WindowWidth, WindowHeight, BufferWidth, BufferHeight, and CursorVisible properties; and the SetWindowPosition, SetBufferSize, and ReadKey methods. En el ejemplo se dibuja un patrón de cuadrícula en el búfer de pantalla basándose en el ancho del búfer de pantalla.The example draws a grid pattern in the screen buffer based on the screen buffer width. Después, el ejemplo mueve la ventana de la consola en respuesta a la flecha arriba, flecha abajo, flecha izquierda o teclas de la consola de la flecha derecha.Then the example moves the console window in response to which of the UP ARROW, DOWN ARROW, LEFT ARROW, or RIGHT ARROW console keys is pressed. El patrón de cuadrícula le ayuda a ver el movimiento de la ventana de la consola con respecto al búfer de pantalla.The grid pattern helps you see the movement of the console window relative to the screen buffer.

La ventana sistema operativo muestra la ventana de la consola y la ventana de la consola muestra una parte del búfer de pantalla.The operating system window displays the console window, and the console window displays a portion of the screen buffer. El SetWindowPosition método afecta a la posición de la ventana de la consola con respecto al búfer de pantalla, pero no afecta a la posición de la ventana del sistema operativo en relación con el escritorio.The SetWindowPosition method affects the position of the console window relative to the screen buffer, but does not affect the position of the operating system window relative to the desktop.

La consola y las ventanas del sistema operativo generalmente no afectan entre sí.The console and operating system windows generally do not affect each other. Sin embargo, si no se puede mostrar el búfer de pantalla en los límites actuales de la ventana de la consola, el sistema operativo anexa automáticamente barras de desplazamiento a la ventana del sistema operativo.However, if the screen buffer cannot be displayed in the current boundaries of the console window, the operating system automatically appends scroll bars to the operating system window.
