Problem when creating a window

[Kubani]

Hi all,

In the following link, there are codes of library files including Window.h and Simple_window.h as well.

http://www.stroustrup.com/Programming/Graphics/

Now when I write below code, there is no problem.

#include <Simple_window.h>

int main()
{
	Simple_window w(Point(100,100), 600, 400, "test");
	return 0;
}

But when I write this one (for using Window rather than Simple_window) I get errors:

#include <Window.h>

int main()
{
	Window w(Point(100,100), 600, 400, "test");
	return 0;
}

5 errors, two of them:
Error 1 error C2065: 'Window' : undeclared identifier c:\users\cs\documents\visual studio 2012\projects\test_3\test_3\test_3.cpp 5

Error 2 error C2146: syntax error : missing ';' before identifier 'w' c:\users\cs\documents\visual studio 2012\projects\test_3\test_3\test_3.cpp 5

I didn't find any case that prevents us from creating a window compared to simple_window.

Window is in the Graph_lib namespace.

#include <Window.h>

int main()
{
    Graph_lib::Window w(Point(100, 100), 600, 400, "test");
}

Thank you very much.
