string theme_config::$csstreepostprocessor = null |
Function to do custom CSS post-processing on a parsed CSS tree.

If the theme does not set characters, appropriate defaults are set automatically. Please DO NOT use < > » - these are confusing for blind users.
array theme_config::$layouts = array() |
Which file to use for each page layout.
This is an array of arrays. The keys of the outer array are the different layouts. Pages in Moodle are using several different layouts like 'normal', 'course', 'home', 'popup', 'form', .... The most reliable way to get a complete list is to look at http://cvs.moodle.org/moodle/theme/base/config.php?view=markup the base theme config.php file. That file also has a good example of how to set this setting.
For each layout, the value in the outer array is an array that describes how you want that type of page to look. For example
$THEME->layouts = array( // Most pages - if we encounter an unknown or a missing page type, this one is used. 'standard' => array( 'theme' = 'mytheme', 'file' => 'normal.php', 'regions' => array('side-pre', 'side-post'), 'defaultregion' => 'side-post' ), // The site home page. 'home' => array( 'theme' = 'mytheme', 'file' => 'home.php', 'regions' => array('side-pre', 'side-post'), 'defaultregion' => 'side-post' ), // ... );
'theme' name of the theme where is the layout located 'file' is the layout file to use for this type of page. layout files are stored in layout subfolder 'regions' This lists the regions on the page where blocks may appear. For each region you list here, your layout file must include a call to
echo $OUTPUT->blocks_for_region($regionname);
or equivalent so that the blocks are actually visible.
'defaultregion' If the list of regions is non-empty, then you must pick one of the one of them as 'default'. This has two meanings. First, this is where new blocks are added. Second, if there are any blocks associated with the page, but in non-existent regions, they appear here. (Imaging, for example, that someone added blocks using a different theme that used different region names, and then switched to this theme.)
string theme_config::$name |
The name of this theme.
Set automatically when this theme is loaded. This can not be set in theme config.php
array theme_config::$parents |
You can base your theme on other themes by linking to the other theme as parents.
This lets you use the CSS and layouts from the other themes (see theme_config::$layouts). That makes it easy to create a new theme that is similar to another one but with a few changes. In this themes CSS you only need to override those rules you want to change.
array theme_config::$parents_exclude_javascripts = null |
The names of all the javascript files from parents that should be excluded.
true value may be used to specify all parents or all themes from one parent. If no value specified value from parent theme used.

If no value specified value from parent theme used.
string theme_config::$rarrow = null |
Accessibility: Right arrow-like character is used in the breadcrumb trail, course navigation menu (previous/next activity), calendar, and search forum block.
If the theme does not set characters, appropriate defaults are set automatically. Please DO NOT use < > » - these are confusing for blind users.
string theme_config::$rendererfactory = 'standard_renderer_factory' |
Name of the renderer factory class to use.
Must implement the renderer_factory interface.
This is an advanced feature. Moodle output is generated by 'renderers', you can customise the HTML that is output by writing custom renderers, and then you need to specify 'renderer factory' so that Moodle can find your renderers.
There are some renderer factories supplied with Moodle. Please follow these links to see what they do.

This may be used to remove cssreset and use cssnormalise module instead.
