=head1 NAME
Gtk2::Ex::FormFactory::Popup - A Popup in a FormFactory framework
=head1 SYNOPSIS
Gtk2::Ex::FormFactory::Popup->new (
...
Gtk2::Ex::FormFactory::Widget attributes
);
=head1 DESCRIPTION
This class implements a Popup in a Gtk2::Ex::FormFactory framework.
The selected entry of the Popup is controlled by the value of the
associated application object attribute, which is either an index in
an array of possible Popup entries or a key of a hash of possible
Popup entries.
Refer to the chapter REQUIREMENTS FOR ASSOCIATED APPLICATION OBJECTS
for details.
=head1 OBJECT HIERARCHY
Gtk2::Ex::FormFactory::Intro
Gtk2::Ex::FormFactory::Widget
+--- Gtk2::Ex::FormFactory::Popup
Gtk2::Ex::FormFactory::Layout
Gtk2::Ex::FormFactory::Rules
Gtk2::Ex::FormFactory::Context
Gtk2::Ex::FormFactory::Proxy
=head1 ATTRIBUTES
Attributes are handled through the common get_ATTR(), set_ATTR()
style accessors, but they are mostly passed once to the object
constructor and must not be altered after the associated FormFactory
was built.
=over 4
=item B<items> = ARRAYREF|HASHREF [optional]
This attribute takes a static list of popup items, if the
popup shouldn't be controlled dynamically by an associated
application object. Refer to the next chapter for details
of the data structure applied here.
=back
=head1 REQUIREMENTS FOR ASSOCIATED APPLICATION OBJECTS
Application objects represented by a Gtk2::Ex::FormFactory::Popup
must define additional methods, unless their content is static
by setting B<items>.
The naming of the methods listed beyond uses the standard
B<get_> prefix for the attribute read accessor. B<ATTR> needs to
be replaced by the actual name of the attribute associated with
the widget.
=over 4
=item B<get_ATTR_list>
This returns the entries of the Popup. Three data models are supported here:
=over 7
=item Simple B<ARRAY>
If the method returns a reference to a simple array, the popup will be filled
with the array values in the original array order.
The index of the actually selected popup entry is stored in the
attribute of the associated application object.
=item Two dimensional B<ARRAY>
The method may return a reference to a two dimensional array. Each row needs to
have the attribute value in the first column and the label for the corresponding
item in the second.
=item B<HASH>
If the method returns a reference to a hash, the popup will be filled
with the alphanumerically sorted hash B<values>.
In turn the hash B<key> of the actually selected popup entry is stored in the
attribute of the associated application object.
