Errors compiling classes with VC++ 6.0

I'm currently trying to write a little program to display a openGl window using C++. I'm using VC++ 6.0.

When compiling I get this error:
error C2679: binary '=' : no operator defined which takes a right-hand operand of type 'class GlWindow *' (or there is no acceptable conversion)

Code:

---

//GlWindow.h
#ifndef _GLWINDOW_H_
#define _GLWINDOW_H_

#include <GL/glui.h>

class GlWindow{
private:
        int x, y, dimx, dimy, attr, ref;
        char *title;

public:
        GlWindow(char *_title);
        GlWindow();

        GlWindow& setPos(int _x, int _y);
        GlWindow& setDim(int _dx, int _dy);
        GlWindow& setAttr(int _attr);
        int show();
};
#endif

//main.c
#include <GL/glui.h>
#include "GlWindow.h"


void display(void){
        glClearColor(0.0, 0.0, 0.0, 0.0);
        glClear(GL_COLOR_BUFFER_BIT);
        glColor3f(1.0, 1.0, 1.0);
        glOrtho(-1.0, 1.0, -1.0, 1.0, -1.0, 1.0);
        glBegin(GL_POLYGON);
        glVertex2f(-0.5, -0.5);
        glVertex2f(-0.5, 0.5);
        glVertex2f(0.5, 0.5);
        glVertex2f(0.5, -0.5);
        glEnd();
        glutSwapBuffers();
}

void keyb(unsigned char key, int x, int y){
        if (key == 27) exit(0);
}

int main(int argc, char *argv[]){
        GlWindow win;

        win = new GlWindow("open Gl");
        win.setPos(100, 100).setDim(300, 300);
        win.show();

        glutKeyboardFunc(keyb);
        glutDisplayFunc(display);

        glutMainLoop();

        return 0;
}

Thanks in advance. ;)

Hi

try this:

Code:

---

       

        GlWindow* win;

        win = new GlWindow("open Gl");
        win->setPos(100, 100).setDim(300, 300);
        win->show();

Arghhh!!
I'm terribly used to Java, and the implict pointer stuff...
sorry.
