Datagrid and Item_click

[Nicolas Aguttes <ni...@gmail.com>]

Hello all,

I have a datagrid (jewel) and I saw that there is a "change" event which is
fired when a line is selected, but is there a way to handle an itemClick
event?

Thanks
Nicolas

No, the code is to be set in your custom itemrenderer. You can
additionally make the event bubbles to the class or mxml file where you
declared your DG and add an event handler to do something there. It's up to
you where to manage.

You can do using a click event too in your itemrenderer mxml root tag

click="doSomething()"

Hello Carlos,

Thanks for your answer, you meant that the listener of the itemclick should
be put at the column level of my data grid?
What I want to achieve is when I click on a line it displays additional
information ad when I click again on the same line it hides them

Hi Nicolas,

itemClicked is dispatched in the renderer of each column list that are
parts of the DataGrid, but is not exposed to the column or the datagrid.

In order to understand what's your need about that low level event can you
elaborate?

In the column list renderer you can listen for that event like this:

override public function addedToParent():void
{
addEventListener("itemClicked", itemClickedEventHandler);
super.addedToParent();
}

private function itemClickedEventHandler(event:Object):void
{
trace("itemClickedEventHandler");
}

you could redispatch a new custom event, and event make it bubble so you
can manage at datagrid use level.

HTH

Carlos
