=head1 DESCRIPTION

Gtk2::ComboBox is a widget that allows the user to choose from a list of valid
choices.  The ComboBox displays the selected choice.  When activated, the
ComboBox displays a popup which allows the user to make a new choice.

Unlike its predecessors Gtk2::Combo and Gtk2::OptionMenu, the Gtk2::ComboBox
uses the model-view pattern; the list of valid choices is specified in the form
of a tree model, and the display of the choices can be adapted to the data in
the model by using cell renderers, as you would in a tree view.  This is
possible since ComboBox implements the Gtk2::CellLayout interface.  The tree
model holding the valid choices is not restricted to a flat list; it can be a
real tree, and the popup will reflect the tree structure.

In addition to the model-view API, ComboBox offers a simple API which is
suitable for text-only combo boxes, and hides the complexity of managing the
data in a model.  It consists of the methods C<new_text>, C<append_text>,
C<insert_text>, C<prepend_text>, C<remove_text> and C<get_active_text>.
