2001-06-05  Havoc Pennington  <hp@redhat.com>

	* gtk/gtkspinbutton.c (gtk_spin_button_set_range): clamp the value
	to the range that was set

	* gtk/gtkrange.c: add value_changed signal, primarily
	intended for use with GtkScale
	(gtk_range_set_increments): new function
	(gtk_range_set_range): new function with weird name
	(gtk_range_set_value): new function
	(gtk_range_get_value): new function

	* gtk/gtkspinbutton.c (gtk_spin_button_get_value): rename
	from gtk_spin_button_get_value_as_float(). Compat #define
	added for get_value_as_float.

	* gtk/gtkhscale.c (gtk_hscale_new_with_range): new function

	* gtk/gtkvscale.c (gtk_vscale_new_with_range): new function

<!-- ##### SECTION Long_Description ##### -->
<para>
A #GtkScale is a slider control used to select a numeric value.
To use it, you'll probably want to investigate the methods on
its base class, #GtkRange, in addition to the methods for #GtkScale itself.
To set the value of a scale, you would normally use gtk_range_set_value().
To detect changes to the value, you would normally use the "value_changed"
signal.

Signal which allows you to change how the scale value is displayed. Connect a
signal handler which returns an allocated string representing @value.
That string will then be used to display the scale's value.
Here's an example signal handler which displays a value 1.0 as
with "-->1.0<--".
