SYNOPSIS
Gtk2::Ex::FormFactory::Popup->new (
...
Gtk2::Ex::FormFactory::Widget attributes
);
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.
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
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.
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.
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
items.
The naming of the methods listed beyond uses the standard get_ prefix
for the attribute read accessor. ATTR needs to be replaced by the
actual name of the attribute associated with the widget.
get_ATTR_list
This returns the entries of the Popup. Three data models are
supported here:
Simple 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.
Two dimensional 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.
HASH If the method returns a reference to a hash, the popup will
be filled with the alphanumerically sorted hash values.
In turn the hash key of the actually selected popup entry is
stored in the attribute of the associated application
object.
