NAME

6       Prima::Tie - tie widget properties to scalars or arrays.
7

DESCRIPTION

9       Prima::Tie contains two abstract classes, "Prima::Tie::Array" and
10       "Prima::Tie::Scalar", which tie an array or a scalar to a widget's
11       arbitrary array or scalar property.  Also, it contains classes
12       "Prima::Tie::items", "Prima::Tie::text", and "Prima::Tie::value", which
13       tie a variable to a widget's items, text, and value property
14       respectively.
15

SYNOPSIS

17               use Prima::Tie;
18
19               tie @items, 'Prima::Tie::items', $widget;
20
21               tie @some_property, 'Prima::Tie::Array', $widget, 'some_property';
22
23               tie $text, 'Prima::Tie::text', $widget;
24
25               tie $some_property, 'Prima::Tie::Scalar', $widget, 'some_property';
26

USAGE

28       These classes provide immediate access to a widget's array and scalar
29       property, in particular to popular properties as items and text. It is
30       considerably simpler to say
31
32               splice(@items,3,1,'new item');
33
34       than to say
35
36               my @i = @{$widget->items};
37               splice(@i,3,1,'new item');
38               $widget->items(\@i);
39
40       You can work directly with the text or items rather than at a remove.
41       Furthermore, if the only reason you keep an object around after
42       creation is to access its text or items, you no no longer need to do
43       so:
44
45               tie @some_array, 'Prima::Tie::items', Prima::ListBox->create(@args);
46
47       As opposed to:
48
49               my $widget = Prima::ListBox->create(@args);
50               tie @some_array, 'Prima::Tie::items', $widget;
51
52       "Prima::Tie::items" requires "::items" property to be available on the
53       widget.  Also, it takes advantage of additional "get_items",
54       "add_items", and the like if available.
55
56   Prima::Tie::items
57       The class is applicable to "Prima::ListViewer", "Prima::ListBox",
58       "Prima::Widget::Header", and their descendants, and in limited fashion
59       to "Prima::OutlineViewer" and its descendants "Prima::StringOutline"
60       and "Prima::Outline".
61
62   Prima::Tie::text
63       The class is applicable to any widget.
64
65   Prima::Tie::value
66       The class is applicable to "Prima::GroupBox",
67       "Prima::Dialog::ColorDialog", "Prima::SpinEdit", "Prima::Gauge",
68       "Prima::Slider", "Prima::CircularSlider", and "Prima::ScrollBar".
