Title: call function in itemRenderer.
Hi friends,
I want to call a frunction from parent script to itemRenderer script.
for eg:
i have one function in my ItemRenderer that is vbox that is in List now i want to call that function from my main file script.
Thanks in advance

any function declared inside item renderer is created for each element in the list. this means if you have 10 items then each one will have its own function. Do you want to call a particular function inside a particular item ?

You have to create an another MXML / AS component of itemrenderer say having name "VBoxRenderer".
public function callIRFun() void{
var rendrerer:VBoxRenderer= leftList.itemRenderer as VBoxRenderer;
rendrerer.dragExitFun();
}
6
if itemRender is as file, try this listData.owner.document

very fast example:
leftList.dataGroup.getElementAt(0)["dragExitFun"]();
cheers !
leftList.dataGroup.getElementAt(0)["dragExitFun"]();
cheers !
