NAME

6       Prima::KeySelector - key combination widget and routines
7

DESCRIPTION

9       The module provides a standard widget for selecting a user-defined key
10       combination. The widget class allows import, export, and modification
11       of key combinations.
12
13       The module provides a set of routines, useful for conversion of a key
14       combination between representations.

SYNOPSIS

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

API

22   Properties
23       key INTEGER
24           Selects a key combination in integer format. The format is
25           described in "Hot key" in Prima::Menu, and is a combination of
26           "km::XXX" key modifiers and either a "kb::XXX" virtual key, or a
27           character code value.
28
29           The property allows almost, but not all possible combinations of
30           key constants. Only "km::Ctrl", "km::Alt", and "km::Shift"
31           modifiers are allowed.
32
33   Methods
34       All methods here can ( and must ) be called without the object syntax;
35       - the first parameter must not be neither package nor widget.
36
37       describe KEY
38           Accepts KEY in integer format, and returns string description of
39           the key combination in human readable format. Useful for supplying
40           an accelerator text to a menu.
41
42                   print describe( km::Shift|km::Ctrl|km::F10);
43                   Ctrl+Shift+F10
44
45       export KEY
46           Accepts KEY in integer format, and returns string with a perl-
47           evaluable expression, which after evaluation resolves to the
48           original KEY value. Useful for storing a key into text config
49           files, where value must be both human readable and easily passed to
50           a program.
51
52                   print export( km::Shift|km::Ctrl|km::F10);
53                   km::Shift|km::Ctrl|km::F10
54
55       shortcut KEY
56           Converts KEY from integer format to a string, acceptable by
57           "Prima::AbstractMenu" input methods.
58
59                   print shortcut( km::Ctrl|ord('X'));
60                   ^X
61
62       translate_codes KEY, [ USE_CTRL = 0 ]
63           Converts KEY in integer format to three integers in the format
64           accepted by "KeyDown" in Prima::Widget event: code, key, and
65           modifier. USE_CTRL is only relevant when KEY first byte ( "KEY &
66           0xFF" ) is between 1 and 26, what means that the key is a
67           combination of an alpha key with the control key.  If USE_CTRL is
68           1, code result is unaltered, and is in range 1 - 26.  Otherwise,
69           code result is converted to the character code ( 1 to ord('A'), 2
70           to ord('B') etc ).
