Opengl Help 

Programming Language: c++

I need help setting coordinate boundries for this program so the shape can't leave the Opengl window. The shape needs to stay visiable. 

GLsizei wh = 500, ww = 500;
GLfloat size = 4.0;
void drawTriangle(int x, int y)
{
glClear (GL_COLOR_BUFFER_BIT);
y = wh = y;
glColor3f(1.0, 0.0, 0.0);
glBegin (GL_POLYGON);
glVertex2f(x + size, y + size);
glVertex2f(x size, y size);
-
glVertex2f(x + size, y
m
size);
glend();
glFlush();
}
void myReshape (GLsizei w, GLsizei h)
{
glMatrixMode (GL_PROJECTION);
glLoadIdentity();
glortho(0.0, (GLdouble)w, 0.0, (GLdouble)h, -1.0, 1.0);
glMatrixMode (GL_MODELVIEW);
glLoadIdentity();
glViewport(0, 0, w, h);
glClearColor(0.0, 0.0, 0.0, 0.0);
glClear (GL_COLOR_BUFFER_BIT);
glFlush();
ww = w;
wh = h;
}
void myinit(void)
{
glViewport(0, 0, ww, wh);
glMatrixMode (GL_PROJECTION);
glLoadIdentity();
glortho(0.0, (GLdouble)ww, 0.0, (GLdouble)wh, -1.0, 1.0);
glClearColor(0.0, 0.0, 0.0, 0.0);
glClear (GL_COLOR_BUFFER_BIT);
glFlush();
glutReshapeFunc (myReshape);
}
void
{
}
void display (void)
{}
mouse(int btn, int state, int x, int y)
if (btn == GLUT_MIDDLE_BUTTON && state == GLUT_DOWN) exit(0);
