44 A layout in kivitendo is anything that should be included into a text/html
45 response without having each controller do it manually. This includes:
59 div containers for error handling and ajax responses
63 javascript and css includes
81 anthing that is not a text/html response
85 All of these tasks are handled by a layout object, which is stored in the
86 global L<$::request|SL::Request> object. An appropriate layout object will be
87 chosen during the login/session_restore process.
92 Every layout must be instantiated from L<SL::Layout::Base> and must implement
93 the following eight callbacks:
99 Content that must, for whatever reason, appear before the main content.
101 =item C<start_content>
103 An introcutory clause for the main content. Usually something like C<< <div
108 The corresponding end of L</start_content> like C<< </div> >>
110 =item C<post_content>
112 Any extra content that should appear after the main content in the response
113 source. Note that it is preferred to put extra content after the main content,
114 so that it gets rendered faster.
118 A list of stylesheets that should be included as a full relative web path. Will
119 be rendered into the html header.
121 =item C<stylesheets_inline>
123 A list of stylesheet snippets that need to be included in the response. Will be
124 added to the html header.
128 A list of javascripts that should be included as a full relative web path.
131 There is no guarantee where these will end up in the content. Currently they
132 will be rendered into the header, but are likely to be moved into the footer in
135 =item C<javascripts_inline>
137 A list of javascript snippets that need to be included in the response.
140 These will end up in the footer, so make sure they don't contain
141 initializations to static javascript includes that may be included earlier.
145 =head1 RUNTIME INTERFACE
147 Each layout object can add stylesheets and javascripts at runtime, as long as
148 its before the actual rendering has begun. This can be used to add special
149 javascripts only your controller needs.
153 =item C<add_stylesheets>
155 Adds the list of arguments to the list of used stylesheets.
157 These will first be searched in the theme folder for the current user, and only
158 after that be searched from the common C<css/> folder.
160 Duplicated files will be only included once.
162 Non-existing files will be pruned from the list.
164 =item C<use_stylesheet>
166 Backwards compatible alias for C<add_stylesheets>. Deprecated.
168 =item C<add_javascripts>
170 Adds the list of arguments to the list of used javascripts.
172 Duplicated files will be only included once.
174 Non-existing files will be pruned from the list.
176 =item C<use_javascript>
178 Backwards compatible alias for C<add_javascripts>. Deprecated.
180 =item C<add_javascripts_inline>
182 Add a snippet of javascript.
184 =item C<add_stylesheets_inline>
186 Add a snippet of css.
190 If set with a selector, the layout will generate javascript to set the page
191 focus to that selector on document.ready.
201 non existing css or js includes should generate a log entry.
