widgets do not appear, due to "event"

[Saquib Malik <saquibfarooq yahoo com>]

The following code is supposed draw a grid of buttons
on the screen, the buttons are being created using a
nested for loop, the whole thing is drawn perfectly
when i try to connect a signal and specifiy the signal
"clicked" but when i use the "event", the screen does
not show up, unless i expand the window to full screen
and then compress it to normal size !!!.

My aim is to make a grid of buttons, each when clicked
causes a pop up menu to be displayed, an option will
be chosed from the menu which will cause a change in
the 'nodes' data structure and then the change will
be visible when the screen is drawn again.

The problem is that whenever the screen is redrawn it
is empty unless I expand it to full screen and
compress it back normal.
void initialize(GtkWidget *);

	win = NULL;

cause the grid to be displayed repaeatedly
