Colour Gradient

[Matthew A Tobiasz <matobias ucalgary ca>]

Hello,

How could I make a widget that shows a colour gradient (eg. a widget that goes 
from one colour to another, that can be used as a scale for a graph).  Like 
the ones in the GIMP, that are used for colour selection of the individual 
colour componenets (hue/saturation/value/red/green/blue).  Thanks.

-Matthew
