I am trying to visualize the network load in a network simulation tool. I
want to display the network nodes as a grid of squares in a window (e.g. a
4x4 mesh network) where I can individually pick the fill-color for each
square based on the traffic across the node (the traffic info has to be
read from a dump file but thats for later). I am trying to see if I can use
pyglet for this. So, for example, lets say we have a 2x2 network (4
squares). I want a 2x2 matrix of squares where I can change the fill-color
of each element individually. I am beginner and so far I have learnt to
draw a single filled square after looking up a lot of references. See the
code:

import sys, time, math, os, random
from pyglet.gl import *
window = pyglet.window.Window()
label = pyglet.text.Label('Simulation',
font_name='Times New Roman',
font_size=16,
color=(204,204,0,255), #red font (255,0,0)
opacity=255
x=window.width, y=window.height,
anchor_x='right', anchor_y='top')
class FilledSquare:
def __init__(self, width, height, xpos, ypos):
self.xpos = xpos
self.ypos = ypos
self.angle = 0
self.size = 1
x = width/2.0
y = height/2.0
self.vlist = pyglet.graphics.vertex_list(4, ('v2f', [-x,-y, x,-y,
-x,y, x,y]), ('t2f', [0,0, 1,0, 0,1, 1,1]),
('c3B',(0,255,0,0,255,0,0,255,0,0,255,0)))
def draw(self,w,h,x,y):
self.width=w
self.height=h
self.xpos=x
self.ypos=y
glPushMatrix()
glTranslatef(self.xpos, self.ypos, 0)
self.vlist.draw(GL_TRIANGLE_STRIP)
glPopMatrix()
@window.event
def on_draw():
window.clear()
glClearColor(0, 0.3, 0.5, 0)
glClear(GL_COLOR_BUFFER_BIT)
label.draw()
square1.draw(60,60,460,240)
square1 = FilledSquare(30, 30, 100, 200)
pyglet.app.run()

1. I think in this way, the fill-color is static as it is initialized.
How can I pass the fill-color?
2. How to create a 2D array of FilledSquare (maybe something like
square[i][j] which I can access in a loop.
Please let me know if it is possible at all. I have already spent a lot of
time and this is not my main focus and I am short of time. I hope its
easier than what I am imagining.
