[Typo3-dev] Configuring tables/fields for listing in Web > Page

[Andrew Henson]

Poking around the changelog I noticed that Kasper has added an API for 
adding extra tables to be listed in the Web > Page module. I have looked 
at the source and found the changes in class.tx_cms_layout and 
db_layout. I have got it working with one of my extensions as follows 
but I would like someone with a bit more Typo3 knowledge to tell me if I 
am doing this in the right way.

Firstly, I couldn't find any functions to add the tables and field lists 
in, can anyone tell me if I have missed it? If there isn't is this 
something that could/should be added into the t3lib_extMgm class?

Secondly, what I did to get it working was to add the following into my 
extensions ext_tables.php file.  Is this the way I should be adding data 
to this array? I suspect not as it presumeably won't take into account 
other peoples extensions which may do the same thing for their 
extension. If not, can anyone tell me a better method?

##not sure if this is the correct way to use the addTables api but it 
seems to generally work
$GLOBALS['TYPO3_CONF_VARS']['EXTCONF']['cms']['db_layout']['addTables'] 
= Array (
	'my_extension_table_name' => Array (
		'0' => Array (
			'fList' => 'fieldname1,fieldname2,fieldname3',
			'icon'=>'0',
			),
		),
	'my_extension_table_name2' => Array (
		'0' => Array (
			'fList' => 'field1,field2',
			'icon' => '1',
			),
		),
	);

Thanks,

Andy
