Need some assistance

[Teslacap]

I am a first year C++ student who doesn't really understand the class and I need some help with a Fox and Hounds Program for my class.
Codes in Question

Line 108   for (int i=0; i<8; ++i)
		for(int j=0; j<8; ++j)
			{
			vr.push_back(new Rectangle(Point(i*50,j*50),50,50));
				if((j+i)%2)
					vr[vr.size()-1].set_fill_color(Color::white);
		    attach(vr[vr.size()-1]);
		    }

Line 240     Vector_ref<Rectangle>vr;
	Image fox, tu1, tu2, tu3, tu4;
	Button next_button; Button next_button2; Button next_button3; Button next_button4;
	Button highscore_button; Button instruction_button; Button begin_button1; Button begin_button2;
	Button begin_button3; Button begin_button4; //Button quit_button;

I can't figure out what the errors want me to do to change the code.
Thanks for any help that you can give.

It looks like there are conflicting definitions for a Rectangle object.

Compiler can't figure out if you mean one of these:
could be...BOOL Rectangle(HDC,int,int,int,int)
or one of these:
or 'c:\...\project\Graph.h(193) : Graph_lib::Rectangle'

Is there a Rectangle defined in Graph.h? Are you using namespace Graph_lib somewhere (commingling namespaces)?

[Teslacap]

Rectangle is defined in Graph.h

struct Rectangle : Shape {

    Rectangle(Point xy, int ww, int hh) : w(ww), h(hh)
    {
        add(xy);
        if (h<=0 || w<=0) error("Bad rectangle: non-positive side");
    }

    Rectangle(Point x, Point y) : w(y.x-x.x), h(y.y-x.y)
    {
        add(x);
        if (h<=0 || w<=0) error("Bad rectangle: non-positive width or height");
    }
    void draw_lines() const;

    int height() const { return h; }
    int width() const { return w; }
private:
    int h;    // height
    int w;    // width
};

and this is in Graph.cpp

void Rectangle::draw_lines() const
{
    if (fill_color().visibility()) {    // fill
        fl_color(fill_color().as_int());
        fl_rectf(point(0).x,point(0).y,w,h);
        fl_color(color().as_int());    // reset color
    }

    if (color().visibility()) {    // lines on top of fill
        fl_color(color().as_int());
        fl_rect(point(0).x,point(0).y,w,h);
    }
}

I have namespace Graph_lib in one of the parts, but taking it off just results in even more problems.

[fun2code]

So, which Rectangle object did you intend to be referring to on the lines in question?

If it's supposed to be a Graph_lib::Rectangle then try qualifying it as such where you are using it.

eg: Line 240 Vector_ref<Graph_lib::Rectangle>vr;

If it's the other , then I don't know.

That fixed most of the errors and I'm going to work on the others. Thanks for all the help!
