Prima::Tie - tie widget properties to scalars or arrays.
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.
Prima::Tie::Array
Prima::Tie::Scalar
Prima::Tie::items
Prima::Tie::text
Prima::Tie::value
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', $widget, 'some_property';
These classes provide immediate access to a widget's array and scalar property, in particular to popular properties as items and text. It is considerably simpler to say
splice(@items,3,1,'new item');
than to say
my @i = @{$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.

get_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.
