Flex 4: Getting a reference to the host application or host mxml from ItemRenderers

Sometimes you have a custom ItemRenderer. That has, perhaps, a button that needs to access one of the methods of you’re main application. how would you accomplish this? read on…

To get a reference to the parent application simply use this:

this.parentApplication

Or if you want to navigate relitavly from the item renderer:

this.parentDocument

If your using a List component this will get a reference to that list

and this will get a reference to that List’s parent document:

this.parentDocument.parentDocument

You can also use these within any mxml document.
