ToolTips

[whitespirit]

Hi, Could someone advise me if tooltips is enabled under PHPExt and
give a sample bit of code on how to add to a toolbar? For example I
have code:

$topbar = new PhpExt_Toolbar_Toolbar();

$searchField = new PhpExtUx_App_SearchField();
$searchField->setStore($store);
$searchField->setWidth(320);


$topbar->addTextItem(4,"Search:");
$topbar->addItem(5, $searchField);

And I would like to add a hint on what kind of searches can be done
for this toolbar item. Thanks in advance for any help.
