NAME

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

DESCRIPTION

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

SYNOPSIS

               use Prima::Tie;

               tie @items, 'Prima::Tie::items', $widget;

               tie @some_property, 'Prima::Tie::Array', $widget, 'some_property';

               tie $text, 'Prima::Tie::text', $widget;

               tie $some_property, 'Prima::Tie::Scalar', $widget, 'some_property';

USAGE

       These classes provide immediate access to a widget's array and scalar property, in
       particular to popular properties as items and text. It is considerably simpler to say

               splice(@items,3,1,'new item');

       than to say

               my @i = @{$widget->items};
               splice(@i,3,1,'new item');
               $widget->items(\@i);

       You can work directly with the text or items rather than at a remove.  Furthermore, if the
       only reason you keep an object around after creation is to access its text or items, you
       no no longer need to do so:

               tie @some_array, 'Prima::Tie::items', Prima::ListBox->create(@args);

       As opposed to:

               my $widget = Prima::ListBox->create(@args);
               tie @some_array, 'Prima::Tie::items', $widget;

       "Prima::Tie::items" requires "::items" property to be available on the widget.  Also, it
       takes advantage of additional "get_items", "add_items", and the like if available.

   Prima::Tie::items
       The class is applicable to "Prima::ListViewer", "Prima::ListBox", "Prima::Header", and
       their descendants, and in limited fashion to "Prima::OutlineViewer" and its descendants
       "Prima::StringOutline" and "Prima::Outline".

   Prima::Tie::text
       The class is applicable to any widget.

   Prima::Tie::value
       The class is applicable to "Prima::GroupBox", "Prima::ColorDialog", "Prima::SpinEdit",
       "Prima::Gauge", "Prima::Slider", "Prima::CircularSlider", and "Prima::ScrollBar".
