php - Change "Click to sort by this column" default text using jHtml::_('grid.sort' -

i'm writing backend component, columns generated this:

<th><?php echo jhtml::_('grid.sort', 'column title', 'table_column', $listdirn, $listorder) ?></th>

in backend, when hold mouse on column header, message: "click sort column."

we want use tool tips , title tag give deeper explanations on each column instead of default message. came across page: https://docs.joomla.org/api17:jhtmljgrid::action

public static function action (     $i     $task     $prefix=''     $text=''     $active_title=''     $inactive_title=''     $tip=false     $active_class=''     $inactive_class=''     $enabled=true     $translate=true     $checkbox='cb' ) 

but have been unsuccessful in getting tooltip fire. ideas on overriding default message?

ok investigated little bit , seems jhtml::_('grid.sort', 'column title', 'table_column', $listdirn, $listorder) triggering jhtmlgrid::sort in libraries/cms/html/grid.php.

this class in particular allow "improve" text in tooltip.
said "improve" because text "click sort column." hardcoded , custom text above text.

to have use following code:

jhtml::_('grid.sort', 'column title', 'table_column', $listdirn, $listorder, null, 'asc', '<h1>here custom code</h1> wow <b>html</b>!'); 

ok want remove "click sort column." , how can ?

create new file in component called mysort.php eg. in there require libraries/cms/html/grid.php , create new class mysort extend jhtmlgrid.

in there copy method sort jhtmlgrid , remove constant jglobal_click_to_sort_this_column.

ok able use mysort::sort('column title', 'table_column', $listdirn, $listorder, null, 'asc', '<h1>here custom code</h1> wow <b>html</b>!');

class mygrid extends jhtmlgrid {     public static function sort($title, $order, $direction = 'asc', $selected = '', $task = null, $new_direction = 'asc', $tip = '')     {         jhtml::_('behavior.core');         jhtml::_('bootstrap.tooltip');          $direction = strtolower($direction);         $icon = array('arrow-up-3', 'arrow-down-3');         $index = (int) ($direction == 'desc');          if ($order != $selected)         {             $direction = $new_direction;         }         else         {             $direction = ($direction == 'desc') ? 'asc' : 'desc';         }          $html = '<a href="#" onclick="joomla.tableordering(\'' . $order . '\',\'' . $direction . '\',\'' . $task . '\');return false;"'             . ' class="hastooltip" title="' . jhtml::tooltiptext(($tip ? $tip : $title)) . '">';          if (isset($title['0']) && $title['0'] == '<')         {             $html .= $title;         }         else         {             $html .= jtext::_($title);         }          if ($order == $selected)         {             $html .= ' <i class="icon-' . $icon[$index] . '"></i>';         }          $html .= '</a>';          return $html;     } }
