Hi Jigal,
Thank you for the explanation and the code.
I renamed tx_iconClass to tx_myext_iconClass. The only other thing I had to
change to make it work is that the iconClass should return
'extensions-myext-mystate' instead of just 'mystate'.
Except clearing the sprites folder in typo3temp I also had to clear the opcode
cache to see my changes, but it worked!
Thanks,
Loek

I'd like to have the backend show a different page icon when something
is set in 'Show Content from Page'. Just like you get a little arrow on
the icon when you make a shortcut.
That would take away a lot of confusion for editors (trying to put
content on a page and wondering why nothing changes, etc).
Any idea how to achieve that?
You can change the page icon itself with a userfunc (the usual overlays are
still applied). This code was used in a 4.x extension. Use the namespaced class
names if you make 6.x specific extensions.
Create an extension. In ext_tables.php:
// Defines $icon array()
$pathToExtension = t3lib_extMgm::extRelPath('<<ext_key>>');
$icons = array(
'mystate' => $pathToExtension .
'Resources/Public/images/icons/mystateicon.png',
'mystate_hide' => $pathToExtension .
'Resources/Public/images/icons/mystateicon_hide.png',
);
// Gives the $icon array to the sprite manager
t3lib_SpriteManager::addSingleIcons($icons, '<<ext_key>>');
// Register userfunc for page icon
$TCA['pages']['ctrl']['typeicon_classes']['userFunc'] =
'tx_iconClass->getPageIcon';
In class.tx_iconClass.php :
class tx_iconClass {
/**
* Determines icon class for special page cases
*
* @param array $parameters array with record
* @param string $ref Unused reference parameters
* @return string Class name of page
*/
public function getPageIcon($parameters, $ref) {
$iconClass = '';
$row = $parameters['row'];
if (....some..condition...) {
$iconClass = 'extensions-<<ext_key>>-mystate';
if ((int)$row['nav_hide'] === 1) {
$iconClass .= '_hide';
}
}
return $iconClass;
}
}
The "hidden" state is a bit special. It doesn't trigger an overlay icon to be
added to the page icon, but it uses a separate icon.
Your special icons are shown everywhere in the backend where the page icon is
usually displayed.
