Exemples
L’exemple suivant illustre les WindowLeft WindowTop Propriétés,, WindowWidth , WindowHeight , BufferWidth , et, ainsi que BufferHeight CursorVisible les SetWindowPosition SetBufferSize méthodes, et ReadKey . L’exemple dessine un modèle de grille dans la mémoire tampon d’écran en fonction de la largeur de la mémoire tampon d’écran. L’exemple déplace ensuite la fenêtre de console en réponse à laquelle l’utilisateur appuie sur les touches de console flèche haut, flèche bas, flèche gauche ou flèche droite. Le modèle de grille vous permet de voir le déplacement de la fenêtre de console par rapport à la mémoire tampon d’écran.

Remarques
La fenêtre du système d’exploitation affiche la fenêtre de console et la fenêtre de console affiche une partie de la mémoire tampon d’écran. La SetWindowPosition méthode affecte la position de la fenêtre de console par rapport à la mémoire tampon d’écran, mais n’affecte pas la position de la fenêtre du système d’exploitation par rapport au bureau.
La console et le système d’exploitation Windows n’affectent généralement pas l’un l’autre. Toutefois, si la mémoire tampon d’écran ne peut pas être affichée dans les limites actuelles de la fenêtre de console, le système d’exploitation ajoute automatiquement des barres de défilement à la fenêtre du système d’exploitation. Dans ce cas, le déplacement des barres de défilement de la fenêtre du système d’exploitation affecte la position de la fenêtre de console et le déplacement de la fenêtre de console avec la SetWindowPosition méthode affecte la position des barres de défilement de la fenêtre du système d’exploitation.
