Hi,
you have to find proper place in code, where RecordBrowser gets displayed and call
// Where $rb is instance of Utils/RecordBrowser
// $rb = $this->init_module('Utils/RecordBrowser', ... );
$rb->disable_actions(array('view', 'edit', 'delete'));
In most cases it's body method of module.
But due to some minor bug, delete action won't dissapear but it will act like you don't have permissions to delete. It's fixed and will be in nearest release, but if you would like to fix this on your installation then go to modules/Utils/RecordBrowser_0.php lines 936-937 and replace them with
if (!isset($da['delete'])) {
if ($this->get_access('delete',$row)) $gb_row->add_action($this->create_confirm_callback_href(__('Are you sure you want to delete this record?'),array('Utils_RecordBrowserCommon','delete_record'),array($this->tab, $row['id'])),'Delete');
else $gb_row->add_action('','Delete',__('You don\'t have permission to delete this record'),null,0,true);
}
Regards,
Adam
