/* PsppireValueEntry is a subclass of GtkComboBox that is specialized for
displaying and entering "union value"s. Its main advantage over a plain
GtkEntry is that, when value labels are supplied, it (optionally) displays
the value label instead of the value. It also allows the user to choose a
new value by label from the drop-down list.
The easiest way to use a PsppireValueEntry is to hand it a particular
variable whose values are to be displayed, using
psppire_value_entry_set_variable(). If you do that, you don't need any of
the other functions to set value labels, format, encoding, width, etc.,
because all of those are determined from the variable. The other functions
are useful if no variable is available. */
