GTK Widgets have a background, a foreground, and a base, each of which is an
array of 5 colors.
The color which is used depends upon the state of the control.
GTK_STATE_NORMAL
GTK_STATE_ACTIVE
GTK_STATE_PRELIGHT -- mouseover, I think.
GTK_STATE_SELECTED,
GTK_STATE_INSENSITIVE
But all controls don't actually make use of all 5 colors, and sometimes it
depends on which theme is in use, so you have to experiment a bit.
You would use it like this:
gtkSet(ctl,"Background",{GTK_STATE_PRELIGHT,#cceeff})

Good idea, except that only 3 of us will see them if we only use this list.
Maybe later more will sign up. Suppose we just post the initial question and
then the final answer (if there is one) to Euforum, to avoid cluttering it
with back-and-forth questions.
