如何创建“ New xxx”弹出窗口？

function page_clients_listing($p){

    $g = $p->add(\'Grid\');
    $g->addColumn(\'text\',\'first_name\');
    $g->addColumn(\'text\',\'last_name\');
    $g->addColumn(\'inline\',\'telephone\');
    $g->addColumn(\'expander\',\'comments\');
    $g->setSource(\'client\');

    $g->addButton(\'With Icon\')->set(\'Add New Client\')->setIcon(\'Plus\');
}

$b=$g->addButton(\'Add New Client\')->setIcon(\'Plus\');

$b->js(\'click\')->univ()->frameURL($title,$url);
// OR
$b->js(\'click\')->univ()->dialogURL($title,$url);

$result = $this->addButton(\'Close\')->js(\'click\')->univ()->closeDialog();
