advance manual needed for module creation..

preferable i’m looking for an indepth manual/example of a custom module creation.
i find it very hard to find more information on this subject by looking at the manuals,
talking to people at IRC #modx channel.

This where i stand but i’m desperatly searching for more advance functions..
modx version 0.9.6.3 Evolution

// -- currently known functionality
include($modx->config[’base_path’]."assets/modules/module_admin/module_admin.php");

$admin_object = new module_admin();
$admin_object->modx = $modx;
$admin_object->table = $admin_object->modx->getFullTableName(’Table_name’) ;
$admin_object->admin_title = ’Custom module administration’;

$admin_object->admin_query = ’query including joins where needed’;

$admin_object->admin_columns = array(
// all fields to show in the list
’table_column_name’=>’user_friendly_name’
,’xxx’=>’yyy’
);

$admin_object->new_link = ’Caption for new object’;
$admin_object->admin_empty = ’Caption for no records found’;
$admin_object->edit_page_title = ’Caption for editing page’;
$admin_object->new_page_title = ’Caption for creating object page’;

$arrDropDownItems = $admin_object->populateDropdown( array( ’unique identifier’, ’table_column_name’ ), ’modx_table_name’, ’conditional equation (true/false as result)’, ’user_friendly_name’, ’ASC’ ) ;

$admin_object->edit_fields = array(
’table_column_name1’ => array( ’type’ =>’text’, ’label’ => ’user_friendly_name’, ’validate_compulsory’ => ’yes’),
’table_column_name2’ => array( ’type’ =>’dropdown’, ’label’ => ’user_friendly_name’, ’values’ => $arrDropDownItems, ’validate_compulsory’ => ’yes’),
);

print $admin_object->display();

// -- wanted information on the following functionality, and more if available
$admin_object->admin_items_per_page
$admin_object->param_error
$admin_object->filter_fields
$admin_object->Edit_query
etcetera..

Serch for the MMM module... ManagerManager Manager...
it is a module to manage the ManagerManager add-on.

It is simple, has good funcionality and it is good to
learn how to implement modules...

I have a tutorial for creating a database management module http://www.sottwell.com/create-module.html

First of all i thank you kindly for the responses. however this is not what i’m looking for.

charliez :
do you have a link or something to describe what you mean (i cannot find anything good Modx related answers from google)

scotwell :
i already found your short tutorial but unfortunaltely this is not what i’m looking for.

í am looking for help on the part of the coding. all the graphical parts i understand (i think) but i desperatly need info on the coding specifics.. (like the documentation of the modx admin object (doxygen like))

Somehow i was looking totally wrong at the problem..

it seems there is a module called "MODx Generic Administration Module" ..

this is where i need some help on.. anybody knows the creator ?
the basic help is not sufficient..
