Starling Feathers Controls PickerList

说明：

The PickerList class displays a Button that may be triggered to show a pop-up List. The way that the list is displayed may be customized for different platforms by changing the picker list's pop-up content manager. Several different options are available, including
drop downs, callouts, and simply filling the stage vertically.

示例：
var list:PickerList = new PickerList();

list.dataProvider = new ListCollection(
[
{ text: "Milk", thumbnail: textureAtlas.getTexture( "milk" ) },
{ text: "Eggs", thumbnail: textureAtlas.getTexture( "eggs" ) },
{ text: "Bread", thumbnail: textureAtlas.getTexture( "bread" ) },
{ text: "Chicken", thumbnail: textureAtlas.getTexture( "chicken" ) },
]);

list.listProperties.itemRendererFactory = function():IListItemRenderer
{
var renderer:DefaultListItemRenderer = new DefaultListItemRenderer();
renderer.labelField = "text";
renderer.iconSourceField = "thumbnail";
return renderer;
};

list.addEventListener( Event.CHANGE, list_changeHandler );

this.addChild( list );

function list_changeHandler(e:Event):void
{
trace(list.selectedItem.text);
}

效果：
