[PD-dev] Pd gui & window codes?

[chun lee]

Hi there:

I have just started to read the source of pd and got this question I wonder
if anyone could give me a hand.

I am interested to know where are the relevant codes for pd's gui & window
rendering. Things like background color of the window, object's color, font
color and so on. could anyone point me to the right direction?

Many thanks
