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

43 Attributes are handled through the common get_ATTR(), set_ATTR() style
44 accessors, but they are mostly passed once to the object constructor
45 and must not be altered after the associated FormFactory was built.
46 attr_select = SCALAR [optional]
48 If you want to track the selection state of the List set the name
49 of the attribute of the associated application object here. An
50 array reference with the indicies of the selected rows (or specific
51 column values if attr_select_column is set) will be managed
52 automatically and stored in this attribute.
53 attr_select_column
55 Normally indicies of the selected rows are stored in the attribute
56 passed with attr_select. Specify a column number here and the
57 corresponding values will be stored instead (e.g. an internal
58 database ID of an invisible column). If you use this you may use
59 the select_row_by_attr() method as well, which is described below.
60 columns = ARRAYREF [mandatory]
62 This is a reference to an array containing the column titles of
63 this list.
64 types = ARRAYREF [optional]
66 You may define types for the columns of the list. The type of a
67 column defaults to 'text'. Other possible types are:
68 text normal text strings
70 markup pango markup strings
71 int integer values
72 double double-precision floating point values
73 bool boolean values, displayed as toggle-able checkboxes
74 scalar a perl scalar, displayed as a text string by default
75 pixbuf a Gtk2::Gdk::Pixbuf
76 editable = ARRAYREF [optional]
78 This an array reference of boolean values, one value for each
79 column. Changes to columns marked editable are synchronized
80 automatically with the associated application object attribute.
81 visible = ARRAYREF [optional]
83 This an array reference of boolean values, one value for each
84 column and controls the visibility of the corresponding columns.
85 Default is to display all columns.
86 selection_mode = 'none'|'single'|'browse'|'multiple' [optional]
88 You may specify a selection mode for the list. Please refer to the
89 Gtk+ documentation of GtkSelectionMode for details about the
90 possible selection modes.
91 update_selection_only = BOOL [optional]
93 If you know the values of your list don't change at runtime, and
94 only the actual selection is important, you should set this to a
95 true value, because updating will be significantly faster, since
96 only the actual selection is affected.
97 For more attributes refer to Gtk2::Ex::FormFactory::Widget.
99
101 $rows = $widget->get_selected_rows ()
102 Returns a list reference of selected row indicies.
103 $data_lref = $widget->get_data ()
105 Returns the data array of the underlying Gtk2::SimpleList. It's a
106 two dimensional array of rows and columns. All manipulations affect
107 the GUI immediately but bypasses all Gtk2::Ex::FormFactory
108 automatic object value update magic, so be careful with this.
109 $widget->select_row_by_attr ($value)
111 Selects a row by a given select_attr attribute value. Works only if
112 select_attr is set for this list.
