NAME

       Gtk2::Ex::FormFactory::List - A List in a FormFactory framework

SYNOPSIS

         Gtk2::Ex::FormFactory::List->new (
           attr_select        => Attribute name for selection tracking,
           attr_select_column => Use this column's value to store in attr_select
           columns            => Titles of the list columns,
           types              => Types of the list columns,
           editable           => Which columns are editable?,
           visible            => Which columns are visible?
           selection_mode     => Selection mode of this list,
           no_header          => Omit header?
           update_selection_only => Boolean, whether updates should only
                                    change the selection, not the list
                                    of values,
           ...
           Gtk2::Ex::FormFactory::Widget attributes
         );

DESCRIPTION

       This class implements a List in a Gtk2::Ex::FormFactory framework (based on
       Gtk2::Ex::Simple::List). The value of the associated application object attribute needs to
       be a reference to a two dimensional array with the content of the list.

OBJECT HIERARCHY

         Gtk2::Ex::FormFactory::Intro

         Gtk2::Ex::FormFactory::Widget
         +--- Gtk2::Ex::FormFactory::List

         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.

       attr_select = SCALAR [optional]
           If you want to track the selection state of the List set the name of the attribute of
           the associated application object here. An array reference with the indicies of the
           selected rows (or specific column values if attr_select_column is set) will be managed
           automatically and stored in this attribute.

       attr_select_column
           Normally indicies of the selected rows are stored in the attribute passed with
           attr_select. Specify a column number here and the corresponding values will be stored
           instead (e.g. an internal database ID of an invisible column). If you use this you may
           use the select_row_by_attr() method as well, which is described below.

       columns = ARRAYREF [mandatory]
           This is a reference to an array containing the column titles of this list.

       types = ARRAYREF [optional]
           You may define types for the columns of the list. The type of a column defaults to
           'text'. Other possible types are:

             text    normal text strings
             markup  pango markup strings
             int     integer values
             double  double-precision floating point values
             bool    boolean values, displayed as toggle-able checkboxes
             scalar  a perl scalar, displayed as a text string by default
             pixbuf  a Gtk2::Gdk::Pixbuf

       editable = ARRAYREF [optional]
           This an array reference of boolean values, one value for each column. Changes to
           columns marked editable are synchronized automatically with the associated application
           object attribute.

       visible = ARRAYREF [optional]
           This an array reference of boolean values, one value for each column and controls the
           visibility of the corresponding columns.  Default is to display all columns.

       selection_mode = 'none'|'single'|'browse'|'multiple' [optional]
           You may specify a selection mode for the list. Please refer to the Gtk+ documentation
           of GtkSelectionMode for details about the possible selection modes.

       update_selection_only = BOOL [optional]
           If you know the values of your list don't change at runtime, and only the actual
           selection is important, you should set this to a true value, because updating will be
           significantly faster, since only the actual selection is affected.

       For more attributes refer to Gtk2::Ex::FormFactory::Widget.

METHODS

       $rows = $widget->get_selected_rows ()
           Returns a list reference of selected row indicies.

       $data_lref = $widget->get_data ()
           Returns the data array of the underlying Gtk2::SimpleList. It's a two dimensional
           array of rows and columns. All manipulations affect the GUI immediately but bypasses
           all Gtk2::Ex::FormFactory automatic object value update magic, so be careful with
           this.

       $widget->select_row_by_attr ($value)
           Selects a row by a given select_attr attribute value. Works only if select_attr is set
           for this list.
