Notes on converting apps from Horde 4 to Horde 5.

These are by far not complete.

++ Mandatory
+++ Use Horde_PageOutput 
 * There is a new class Horde_PageOutput which is an OO-style output buffer
 * horde/templates/common-header.inc++++ common header to $page_output->header

horde/templates/common-header.inc does not exist anymore

@@---require $registry->get('templates', 'horde') . '/common-header.inc'; 
echo Horde::menu();@@
@@+++ $page_output->header(array(
    'title' => _("List")

++++ Page Footer
@@---require $registry->get('templates', 'horde') . '/common-footer.inc';@@

++++ Adding Javascript
@@---Horde::addScriptFile('jquery-ui/jquery-1.7.min.js', 'insysgui');@@

+++ New parameter format for entries in menu
In Application.php's menu function, entries now go like this

            $menu->add(Horde::url('data.php'), _("_Import/Export"), 'horde-data');

It's link, caption, css class. The Icon now has to be defined in css:

.turba-edit, #tabEditContact a {
    background-image: url("graphics/edit.png");


++ UI
+++ Topbar search bar
 * If your app sported a custom search bar (like wicked, sesha or whups), convert it to the Horde Topbar

$topbar = $injector->getInstance('Horde_View_Topbar');
/* Make topbar visible */
$topbar->search = true;
/* Define where to redirect when the button is clicked */
$topbar->searchAction = new Horde_Url('list.php');
/* Define the grayed-out hint text in the search field */
$topbar->searchLabel =  $session->get('sesha', 'search') ?: _("Stock Id");
/* Define a search icon. Leave away if you want the default */
$topbar->searchIcon = Horde_Themes::img('search-topbar.png');

+++ Custom apps handling
If your conf.xml had such a section

<configsection name="menu">
  <configheader>Menu Settings</configheader>
  <configmultienum name="apps" desc="Select any applications that should be
  linked in Insysgui's menu" required="false">
    <configspecial application="horde" name="apps" />

drop it. It won't work anymore now that the app-specific menu lives in the sidebar.
