Widget visibility settings?

[opentype]

I’m updating a plugin to 4.5 which contains widgets. The widget settings now automatically contain a Visibility tab—but it’s empty. 

How is that controlled? How to add the actual visibility settings? Or how to turn that off? I checked the forum and the developer section, but I don’t see any information about this.

Make sure your configuration method starts with:

	public function configuration( &$form=null )
 	{
		$form = parent::configuration( $form );

That’s it. Thanks.
