9 my $action = Padre::Wx::Action->new(
10 name => 'file.save',
11 label => 'Save',
12 comment => 'Saves the current file to disk',
13 icon => '...',
14 shortcut => 'Ctrl-S',
15 menu_event => sub { },
16 );
17
19 This is the base class for the Padre Action API.
20
22 Each module is constructed using a number of keys. While only the name
23 is technically required there are few reasons for actions which lack a
24 label or menu_event.
25
26 The keys are listed here in the order they usually appear.
27
28 name
29 Each action requires an unique name which is used to reference and call
30 it.
31
32 The name usually has the syntax
33
34 group.action
35
36 Both group and action should only contain \w+ chars.
37
38 label
39 Text which is shown in menus and allows the user to see what this
40 action does.
41
42 Remember to use Wx::gettext to make this translatable.
43
44 need_editor
45 This action should only be enabled/shown if there is a open editor
46 window with a (potentially unsaved) document in it.
47
48 The action may be called anyway even if there is no editor (all
49 documents closed), but it shouldn't.
50
51 Set to a value of 1 to use it.
52
53 need_file
54 This action should only be enabled/shown if the current document has a
55 file name (meaning there is a copy on disk which may be older than the
56 in-memory document).
57
58 The action may be called anyway even if there is no file name for the
59 current document, but it shouldn't.
60
61 Set to a value of 1 to use it.
62
63 need_modified
64 This action should only be enabled/shown if the current document has
65 either been modified after the last save or was never saved on disk at
66 all.
67
68 The action may be called anyway even if the file is up-to-date with the
69 in-memory document, but it shouldn't.
70
71 Set to a value of 1 to use it.
72
73 need_selection
74 This action should only be enabled/shown if there is some text selected
75 within the current document.
76
77 The action may be called anyway even if nothing is selected, but it
78 shouldn't.
79
80 Set to a value of 1 to use it.
81
82 need
83 Expected to contain a CODE reference which returns either true or
84 false.
85
86 If the code returns true, the action should be enabled/shown, otherwise
87 it shouldn't, usually because it won't make sense to use this action
88 without whatever_is_checked_by_the_code. (For example, UNDO can't be
89 used if there was no change which could be undone.)
90
91 The CODE receives a list of objects which should help with the
92 decision:
93
94 config Contains the current configuration object
95 editor The current editor object
96 document The current document object
97 main The main Wx object
98
99 A typical sub for handling would look like this:
100
101 need => sub {
102 my $current = shift;
103 my $editor = $current->editor or return 0;
104 return $editor->CanUndo;
105 },
106
107 Use this with caution! As this function is called very often there are
108 few to no checks and if this isn't a CODE reference, Padre may crash at
109 all or get very slow if your CODE is inefficient and requires a lot of
110 processing time.
111
112 comment
113 A comment (longer than label) which could be used in lists. It should
114 contain a short description of what this action does.
115
116 Remember to use Wx::gettext to make this translatable.
117
118 icon
119 If there is an icon for this action, specify it here.
120
121 shortcut
122 The shortcut may be set by the user. This key sets the default shortcut
123 to be used if there is no user-defined value.
124
125 menu_event
126 This is expected to contain a CODE reference which does the job of this
127 action or an ARRAY reference of CODE references which are executed in
128 order.
129
131 new
132 A default constructor for action objects.
