[SOLVED] New tab in back office by module

[muirch]

I am creating a module, which need some user-content administration.
Is it possible to make a new tab with administration functional in back office under "Clients"?
How I can make a module, which do that?

[Yann - Prestaplugins]

$tab = new Tab();
foreach (Language::getLanguages() as $language) {
     $tab->name[$language['id_lang']] = 'Your label here';
}
$tab->class_name = 'your tab classname here';
$tab->module = 'your module name here';
$tab->id_parent = 2;
$tab->save();

Where I must put this code?

Copy one of the files in the admin/tabs directory and create your tab based on that. Once you've done that, go to Tools > Tabs, create a new tab, enter the tab text under "Name", enter the class name under "Class" (for example, AdminYourTab), then choose "Customer" as the parent category.

Thanks to Patanock and rocky.
Also, we can leave tab file in module folder, its not neccesary to put it to admin/tabs

Now I have another one question:
how to remove module tab during module uninstall process?

[muirch]

I spend some time and now I will show complete solution - what we need to do to use back office tab, created by our module.
1. In instalation process we must eval this:

$tab = new Tab();
foreach (Language::getLanguages() as $language) {
     $tab->name[$language['id_lang']] = 'Tab Name';
}
$tab->class_name = 'AdminModuleName'; // you need to write tab code in AdminModuleName.php in module folder
$tab->module = 'modulename'; // module name and folder
$tab->id_parent = 2; / / parent tab ID
$r = $tab->save(); // saving your tab
Configuration::updateValue('MODULENAME_TAB_ID', $tab->id); // saving tab ID to remove it when uninstall 

2. When uninstall module :

$tab = new Tab(Configuration::get('MYMESSAGE_TAB_ID'));
$tab->delete();

Hope this information be usefull.
