setcurrentwindow

Syntax

#include "graphics.h"
void setcurrentwindow(int window);

Description

The setcurrentwindow function is available in the winbgim implementation of BGI graphics. You do not need to include conio.h; just include graphics.h.

The function changes the current window for all graphics operations to the specified window. This window number must be a number returned by the initiwindow functiion. The current window is the window where all other graphics operations will take place.

Note: Initwindow and initgraph both set the current window to the newly created window, so there is no need to call setcurrentwindow immediately after opening a new window. parameters have default values.
