How to center vbox inside full screen window

[Christian Smith <Christian Smith Sun COM>]

Hi All,

I have a very simple GTK program (in C) that creates a full screen 
window.  Inside the full screen window I am placing a vbox with two 
elements inside: and image and a label.

For the life of me I cannot figure out how to get the contents of the 
vbox to be packed together.  I.e. I want the image + label touching each 
other and centered on the screen.  Currently the height of the vbox 
seems to fill the height of the screen with the image and label 
distributed inside (and not touching).

Any help is appreciated!

Thanks,
Christian
