NAME

       Prima::KeySelector - key combination widget and routines

DESCRIPTION

       The module provides a standard widget for selecting a user-defined key combination. The widget class allows import, export, and
       modification of key combinations.

       The module provides a set of routines, useful for conversion of a key combination between representations.

SYNOPSIS

	       my $ks = Prima::KeySelector-> create( );
	       $ks-> key( km::Alt | ord('X'));
	       print Prima::KeySelector::describe( $ks-> key );

API

   Properties
       key INTEGER
	   Selects a key combination in integer format. The format is described in "Hot key" in Prima::Menu, and is a combination of "km::XXX" key
	   modifiers and either a "kb::XXX" virtual key, or a character code value.

	   The property allows almost, but not all possible combinations of key constants. Only "km::Ctrl", "km::Alt", and "km::Shift" modifiers
	   are allowed.

   Methods
       All methods here can ( and must ) be called without the object syntax; - the first parameter must not be neither package nor widget.

       describe KEY
	   Accepts KEY in integer format, and returns string description of the key combination in human readable format. Useful for supplying an
	   accelerator text to a menu.

		   print describe( km::Shift|km::Ctrl|km::F10);
		   Ctrl+Shift+F10

       export KEY
	   Accepts KEY in integer format, and returns string with a perl-evaluable expression, which after evaluation resolves to the original KEY
	   value. Useful for storing a key into text config files, where value must be both human readable and easily passed to a program.

		   print export( km::Shift|km::Ctrl|km::F10);
		   km::Shift|km::Ctrl|km::F10

       shortcut KEY
	   Converts KEY from integer format to a string, acceptable by "Prima::AbstractMenu" input methods.

		   print shortcut( km::Ctrl|ord('X'));
		   ^X

       translate_codes KEY, [ USE_CTRL = 0 ]
	   Converts KEY in integer format to three integers in the format accepted by "KeyDown" in Prima::Widget event: code, key, and modifier.
	   USE_CTRL is only relevant when KEY first byte ( "KEY & 0xFF" ) is between 1 and 26, what means that the key is a combination of an
	   alpha key with the control key.  If USE_CTRL is 1, code result is unaltered, and is in range 1 - 26.  Otherwise, code result is
	   converted to the character code ( 1 to ord('A'), 2 to ord('B') etc ).
