Tilelist Custom Selected Item Skin

[Chris Ivens]

Has anyone found a solution to this? I'm trying to do a similar thing. It would be great if it were possible to detect whether the item is selected or not within an itemRenderer.

I think I have a way of making it work without too many overheads. ListBase has
a few functions to help with the drawing of items so overriding them and adding
a little extra functionality seemed to be easy enough.

Create a custom actionscript class that extends the relevant list type; in my
case TileList. Override the drawItem method to pass the 'selected' variable
into the itemRenderer.

So basically the item is your itemrenderer and calling a setter/getter or any
other method is possible as the item is drawn. Seems to work well for me.



package com.example.controls {
import mx.controls.TileList;
import mx.controls.listClasses.IListItemRenderer;
import com.example.ir.*;

public class ToggleList extends TileList {

public function ToggleList() {
super();
}

override protected function drawItem(item:IListItemRenderer,
selected:Boolean = false,
highlighted:Boolean = false,
caret:Boolean = false,
transition:Boolean = false):void {
super.drawItem(item, selected, highlighted, caret, transition);
SomeItemRenderer(item).toggleSelection(selected);
}

}
}
