NAME

       Prima::Image::TransparencyControl - standard dialog for transparent color index selection.

DESCRIPTION

       The module contains two classes - "Prima::Image::BasicTransparencyDialog" and "Prima::Image::TransparencyControl". The former provides a
       dialog, used by image codec-specific save options dialogs to select a transparent color index when saving an image to a file.
       "Prima::Image::TransparencyControl" is a widget class that displays the image palette and allow color rather than index selection.

Prima::Image::TransparencyControl
   Properties
       index INTEGER
	   Selects the palette index.

       image IMAGE
	   Selects image which palette is displayed, and the color index can be selected from.

   Events
       Change
	   Triggered when the user changes "index" property.

Prima::Image::BasicTransparencyDialog
   Methods
       transparent BOOLEAN
	   If 1, the transparent selection widgets are enabled, and the user can select the palette index. If 0, the widgets are disabled; the
	   image file is saved with no transparent color index.

	   The property can be toggled interactively by a checkbox.

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".
