how to wrk wid colors?

["sahlot arvind" <asahlot gmail com>]

I want to draw adjacent rectangles of different color wid a time delay...

if i use pixmap then whole of the figure will get up instataneoulsy,
but i want to show sth like animation...so for that i implemented a
function to draw rectangle wid color then i used
g_timeout_add(1000,draw_rect, NULL).. now for each successive call i m
changing coordinates and alongwid them i m using
gdk_gc_set_foreground(gc, &color).. i m not doing anything wid
background color but background color is itself changing to foreground
color and the lines which are drawing rectangle are of same color as
that of filled rectangle.. while i want to draw rectangle in BLACK and
wanna fill it wid RED....

I am getting any way out so plz help me..

Thanks and Regards
