gwy_val_unit_new ()

GtkWidget*  gwy_val_unit_new                (gchar *label_text,
                                             GwySIUnit *si_unit);

Creates label, adjustment and selection to set value with unit.

`label_text` :	label to appear on the left side
`si_unit` :	base unit to appear on the right side
Returns :	new widget.

gwy_val_unit_set_value ()

void        gwy_val_unit_set_value          (GwyValUnit *val_unit,
                                             gdouble value);

`val_unit` :	GwyValUnit widget
`value` :	value to be set

gwy_val_unit_get_value ()

gdouble     gwy_val_unit_get_value          (GwyValUnit *val_unit);

Computes actual value of adjustment and unit prefix.

`val_unit` :	GwyValUnit widget
Returns :	actual value

gwy_val_unit_signal_value_changed ()

void        gwy_val_unit_signal_value_changed
                                            (GwyValUnit *val_unit);

The "value-changed" signal

void        user_function                  (GwyValUnit *gwyvalunit,
                                            gpointer user_data);

`gwyvalunit` :	the object which received the signal.
`user_data` :	user data set when the signal handler was connected.
