just grab the relevant navigation key press events from the entry
button, and bind them to the same functions as the mouse. works like a
charm, although it forces me to override what i regard as a poor
decision in GTK+ : the default use of TAB and Up/Down for focus navigation.

Personally, I use a CList for this, with the widget size set to show
just enough of a scroll bar that navigation is possible.

But for other reasons, I think I may soon need to cook up a version of
the spinbutton that is more programmer-customizable. XForms has a nice
model of such a beast, where the display values of the button not
necessarily numeric, and a filter function is called to take the
current numeric value and convert it to some representation. If the
filter is NULL, it just prints it with some specified precision. This
is much friendlier than the current spin button, which is inevitably
tied to numbers.
