+=head1 NAME
+
+SL::Layout::ActionBar::Action - base class for action bar actions
+
+=head1 DESCRIPTION
+
+This base class for actions can be used to implement elements that can be
+added to L<SL::Layout::ActionBar>.
+
+Elements can be interactive or simply used for layout. Most of the actual
+semantics are handled in the corresponding javascript C<js/kivi.ActionBar.js>, so
+this is only used to generate the DOM elements and to provide information for
+request time logic decisions.
+
+
+=head1 SYNOPSIS
+
+  # implement:
+  package SL::Layout::ActionBar::Custom;
+  use parent qw(SL::Layout::ActionBar::Action);
+
+  # unsugared use
+  SL::Layout::ActionBar::Custom->new(
+    text   => t8('Description'),
+    params => {
+      key => $attr,
+      key => $attr,
+      ...
+    },
+  );
+
+  # parse sugared version:
+  SL::Layout::ActionBar::Custom->from_params(
+    t8('Description'),
+    key => $attr,
+    key => $attr,
+    ...
+  );
+
+=head1 INTERFACE
+
+=over 4
+
+=item * C<render>
+
+Needs to be implemented. Should render only the bare minimum necessary to
+identify the element at run time.
+
+=item * C<script>
+
+Will be called during layout rendering. Defaults to dumping the params section
+into data field of the rendered DOM element.
+
+=item * C<from_params>
+
+Parse sugared version. Defaults for historic reasons to the implementation of
+L<SL::Layout::ActionBar::Submit>, all others must implement their own.
+
+=item * C<callable>
+
+Used to determine whether an instance is callable or only a layout element.
+
+=back
+
+=head1 METHODS
+
+=over 4
+
+=item * C<p>
+
+Returns the current request presenter.
+
+=item * C<id>
+
+Will get initialized to either the provided id from the params or to a
+generated unique id. Should be used to tie the rendered DOM and script
+together.
+
+=back
+
+=head1 RECOGNIZED PARAMETERS
+
+=over 4
+
+=item * C<< submit => [ $selector, \%params ] >>
+
+On click, submit the form found with the first parameter. If params is present
+and a hashref, the key value elements will be added to the form before
+submitting. Beware that this will destroy the form if the user uses the browser
+history to jump back to this page, so ony use parametrized submits for post
+submits that redirect on completion.
+
+=item * C<< link => $url >>
+
+On click, will load the given url.
+
+=item * C<< call => [ $function_name, @args ] >>
+
+On click, will call the function name with the argument array. The return will
+be discarded. It is assumed that the fucntion will trigger an asynchronous
+action.
+
+Contrast with C<checks>.
+
+=item * C<< checks => \@function_names >>
+
+Before any of C<submit>, C<link>, or C<call> are evaluated all
+functions in C<check> are called. Only if all of them return a true value the
+action will be triggered.
+
+Checks are expected not to trigger asynchronous actions (contrast with C<call>),
+but may change the DOM to indicate to the user why they fail.
+
+Each must return a boolean value.
+
+=item * C<< confirm => t8('Yes/No Question') >>
+
+Before any of C<submit>, C<link>, or C<call> are evaluated, the user
+will be asked to confirm. If checks are present and failed, confirm will not be
+triggered.
+
+=item * C<< only_if => $bool >>
+
+Pseudo parameter. If present and false, the element will not be rendered.
+
+=item * C<< not_if => $bool >>
+
+Pseudo parameter. If present and true, the element will not be rendered.
+
+=item * C<< only_once => 1 >>
+
+If present, a click will C<disable> the action to prevent multiple activations.
+
+=item * C<< accesskey => $text >>
+
+Registers an accesskey for this element. While the most common accesskey is
+'enter', in theory every other should work as well. Modifier keys can be added
+to the accesskey string with 'ctrl+', 'alt+', or 'shift+'. 'shift+' is not
+necessary for upper case letters.
+
+=item * C<< disabled => t8('tooltip') >>
+
+Renders the element disabled, ignores all actions (C<submit>, C<call>, C<link>)
+and adds the given tooltip hopefully explaining why the element is disabled.
 
-planned options for clickables:
+=item * C<< id => $id >>
 
-- checks => [ ... ] (done)
+Sets the DOM id of the rendered element. If missing, the element will get a
+random id.
 
-a list of functions that need to return true before submitting
+=item * C<< tooltip => t8('tooltip') >>
 
-- submit => [ form-selector, { params } ] (done)
+Sets a tooltip for the element.
 
-on click submit the form specified by form-selector with the additional params
+=back
 
-- function => function-name (done)
+=head1 BUGS
 
-on click call the specified function (is this a special case of checks?)
+None yet :)
 
-- disabled => true/false/tooltip explaning why disabled (done)
