I've got an ADG where each leaf node has one of 2 icons: a plus (if the item is
known as an adder) or a trash can (otherwise).

I've got the icon being set by iconfunction using the attached code.

How do I set it so that the user can click the icon and trigger a given
function (deleteItem in the case of the trashcan). Do I have to use a custom
itemRenderer with a button instead of an icon? I'd rather not, since I can't
seem to get my item renderers to make sense.


public function setIcon(item:Object):Class
{
if(item.hasOwnProperty('adder') && item['adder']==1)
return add;
else if(!item.hasOwnProperty('children'))//If there are children, the node
is a branch, so we don't want to enable deleting
return trash;
return null;
}

In your itemClick, look at the same information you look at in the
iconFunction property...

Thanks for the answer.

I've thought of that, however, I want to react differently when clicking the
icon than when clicking the row.

When clicking the row, the item editor opens up. If the trash can is clicked,
the user is prompted to delete the item

You still can determine if the situation is appropriate by looking at
exactly the same information.

How?

If the person clicks on the row itself, the editor opens up. If they click on
the trash, the item should be deleted. The info stored in the item will not
determine if the user want's to delete or edit the item.

Ah, I thought that the problem was that you didn't know which ones _had_
trash can icons. Edit your itemRenderer to generate a different event when
the trash can is clicked.

It's all good.

That's the problem I'm facing. I have no clue how to generate a different
event when the can is clicked.

Right now I'm not using a custom item renderer. I just used iconFunction to
make the icons.

I've tried the custom renderer, however, they don't indent to follow the tree
once it's expanded. They all align to the left..

You might be able to use a click event and look at the event.target and see
what the className is of the target. Then you'll have to walk up from there
to get the renderer itself and look at the data.

Or you could just subclass the AdvancedDataGridGroupItemRenderer and add an
event listener to the icon...
