Question

How can I stack up these two opengl shapes into a container class?
can someone please show me
I wont mind a template.

void myTriangle()
 {
glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT); 
glLoadIdentity();                                   
glTranslatef(-1.5f,0.0f,-6.0f);                     
glBegin(GL_TRIANGLES);                      
    glColor3f(1.0f,0.0f,0.0f);                      
    glVertex3f( 0.0f, 1.0f, 0.0f);                  
    glColor3f(0.0f,1.0f,0.0f);                      
    glVertex3f(-1.0f,-1.0f, 0.0f);                  
    glColor3f(0.0f,0.0f,1.0f);                      
    glVertex3f( 1.0f,-1.0f, 0.0f);                  
glEnd();
glutSwapBuffers ( );
  }

void myQuad()
 {
glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT); 
    glLoadIdentity();
glColor3f(0.5f,0.5f,1.0f);                      
    glBegin(GL_QUADS);                              
      glVertex3f(-1.0f, 1.0f, 0.0f);                    
      glVertex3f( 1.0f, 1.0f, 0.0f);                    
      glVertex3f( 1.0f,-1.0f, 0.0f);                    
      glVertex3f(-1.0f,-1.0f, 0.0f);                    
    glEnd();
glutSwapBuffers ( );
     }

not really sure of what you want to do, but you can do:

typedef void (*ShapeFct_t)();
typedef std::vector<ShapeFct_t> ShapeArray_t;

ShapeArray_t shapes;
shapes.push_back(myTriangle);
shapes.push_back(myQuad);
