Scale Widget Problems

["David M. Rector" <dave clean lanl gov>]

Please help,

I have set up a window with many scale widgets, upon changing the value of
one scale widget, I change the adjustments of the other scale widgets to
reflect new values and upper and lower limits.

There are several issues:

1) Simply issuing "gtk_adjustment_new" does not redraw the scale widget
	neither does "gtk_adjustment_changed", the old values still
	appear in the widgets.

2) When I use "gtk_widget_draw", the new values are drawn, however since
	the upper limit has changed, the value text gets ugly if the new
	upper limit has more digits then the old upper value. Appearantly,
	the text space for the additional digits is not cleared. My guess
	is that the size of the scale widget needs to change to allow for
	the extra digits, but none of the above functions update the size
	of the widget.

3) The only way I could get the text to clear properly when the new upper
	limit is bigger than the old one is to redraw the whole window,
	which takes a long time. Also, the only way I could get the scale
	widgets to resize properly to reflect the new upper limit digits
	is to resize the whole window. Which also takes a long time.

4) I think I need a way to "reserve" space in the value display region of
	the scale widget so that when the upper limit changes, the space
	is properly cleared between new values.

Thanks for your help.
