The #GtkRange::change-value signal is emitted when a scroll action is
performed on a range. It allows an application to determine the
type of scroll event that occurred and the resultant new value.
The application can handle the event itself and return %TRUE to
prevent further processing. Or, by returning %FALSE, it can pass
the event to other handlers until the default GTK+ handler is
reached.
The value parameter is unrounded. An application that overrides
the GtkRange::change-value signal is responsible for clamping the
value to the desired number of decimal digits; the default GTK+
handler clamps the value based on #GtkRange:round-digits.
It is not possible to use delayed update policies in an overridden
#GtkRange::change-value handler.
