[TYPO3] Example with flexform

[Livius Agrippa]

Hi,

I try to create an extension which use flexform. This extension should
process select statements on other database than typo3-install database.

Also I try to populate the items in the flexform with information from
the other database.
Are there more examples with itemsProcFunc functions similar with:
class.tx_ttnews_itemsProcFunc.php ?

Because I don't know how to access the connection information from the
main class of the extension.

Any information will be really appreciated,
Livius
