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<--".
|[<!-- language="C" -->
static gchar*
format_value_callback (GtkScale *scale,
gdouble value)
{
return g_strdup_printf ("-->\%0.*g<--",
gtk_scale_get_digits (scale), value);
}
