Product Version : | Feathers 1.0.0 |
Layouts may be, and are highly encouraged to be, virtual, meaning that the List is capable of creating a limited number of item renderers to display a subset of the data provider instead of creating a renderer for every single item. This allows for optimal performance with very large data providers.
The following example creates a grouped list, gives it a data provider, tells the item renderer how to interpret the data, and listens for when the selection changes:
var list:GroupedList = new GroupedList(); list.dataProvider = new ArrayHierarchicalCollection( [ { header: "Dairy", children: [ { text: "Milk", thumbnail: textureAtlas.getTexture( "milk" ) }, { text: "Cheese", thumbnail: textureAtlas.getTexture( "cheese" ) }, ] }, { header: "Bakery", children: [ { text: "Bread", thumbnail: textureAtlas.getTexture( "bread" ) }, ] }, { header: "Produce", children: [ { text: "Bananas", thumbnail: textureAtlas.getTexture( "bananas" ) }, { text: "Lettuce", thumbnail: textureAtlas.getTexture( "lettuce" ) }, { text: "Onion", thumbnail: textureAtlas.getTexture( "onion" ) }, ] }, ]); list.itemRendererFactory = function():IGroupedListItemRenderer { var renderer:DefaultGroupedListItemRenderer = new DefaultGroupedListItemRenderer(); renderer.labelField = "text"; renderer.iconSourceField = "thumbnail"; return renderer; }; list.addEventListener( Event.CHANGE, list_changeHandler ); this.addChild( list );

dataProvider | property |
dataProvider:IHierarchicalCollection
The collection of data displayed by the list. Changing this property to a new value is considered a drastic change to the list's data, so the horizontal and vertical scroll positions will be reset, and the list's selection will be cleared.
The following example passes in a data provider and tells the item renderer how to interpret the data:
list.dataProvider = new ArrayHierarchicalCollection( [ { header: "Dairy", children: [ { text: "Milk", thumbnail: textureAtlas.getTexture( "milk" ) }, { text: "Cheese", thumbnail: textureAtlas.getTexture( "cheese" ) }, ] }, { header: "Bakery", children: [ { text: "Bread", thumbnail: textureAtlas.getTexture( "bread" ) }, ] }, { header: "Produce", children: [ { text: "Bananas", thumbnail: textureAtlas.getTexture( "bananas" ) }, { text: "Lettuce", thumbnail: textureAtlas.getTexture( "lettuce" ) }, { text: "Onion", thumbnail: textureAtlas.getTexture( "onion" ) }, ] }, ]); list.itemRendererFactory = function():IGroupedListItemRenderer { var renderer:DefaultGroupedListItemRenderer = new DefaultGroupedListItemRenderer(); renderer.labelField = "text"; renderer.iconSourceField = "thumbnail"; return renderer; };
Warning: A grouped list's data provider cannot contain duplicate items. To display the same item in multiple item renderers, you must create separate objects with the same properties. This restriction exists because it significantly improves performance.
Warning: If the data provider contains display objects,
concrete textures, or anything that needs to be disposed, those
objects will not be automatically disposed when the grouped list is
disposed. Similar to how starling.display.Image
cannot
automatically dispose its texture because the texture may be used
by other display objects, a list cannot dispose its data provider
because the data provider may be used by other lists. See the
dispose()
function on IHierarchicalCollection
to see how the data provider can be disposed properly.
The default value is null

footerRendererProperties | property |
footerRendererProperties:Object
An object that stores properties for all of the list's footer
renderers, and the properties will be passed down to every footer
renderer when the list validates. The available properties
depend on which IGroupedListHeaderOrFooterRenderer
implementation is returned by footerRendererFactory
.
By default, the footerRendererFactory
will return a
DefaultGroupedListHeaderOrFooterRenderer
instance. If
you aren't using a custom footer renderer, you can refer to
feathers.controls.renderers.DefaultGroupedListHeaderOrFooterRenderer
for a list of available properties.
These properties are shared by every footer renderer, so anything
that cannot be shared (such as display objects, which cannot be added
to multiple parents) should be passed to footer renderers using the
footerRendererFactory
or in the theme.
The following example customizes some footer renderer properties:
list.footerRendererProperties.contentLabelField = "footerText"; list.footerRendererProperties.contentLabelStyleName = "custom-footer-renderer-content-label";
If the subcomponent has its own subcomponents, their properties
can be set too, using attribute @

,
which is in a List
, you can use the following syntax:

Returns the current footer renderer used to render specific footer

headerDataToHeaderRenderer | () | method |
public function headerDataToHeaderRenderer(headerData:Object):IGroupedListHeaderRenderer
Returns the current header renderer used to render specific header
data. May return null
if the header data doesn't
currently have a header renderer. Most lists use virtual layouts
where only the visible headers will have a header renderer, so the
result will usually be null
for most header data in the
data provider.

Returns the current item renderer used to render a specific item. May
return null
if an item doesn't currently have an item
renderer. Most lists use virtual layouts where only the visible items
will have an item renderer, so the result will usually be

event listener that handles the event. For example, if you use
myButton.addEventListener() to register an event listener,
myButton is the value of the currentTarget . |
data | The item associated with the item renderer that was triggered. |
target | The Object that dispatched the event;
it is not always the Object listening for the event. Use the
currentTarget property to always access the Object
listening for the event. |
layout | style |
layout:ILayout
The layout algorithm used to position and, optionally, size the list's items.
By default, if no layout is provided by the time that the list initializes, a vertical layout with options targeted at touch screens is created.
The following example tells the list to use a horizontal layout:
var layout:HorizontalLayout = new HorizontalLayout(); layout.gap = 20; layout.padding = 20; list.layout = layout;
keyScrollDuration | style |
keyScrollDuration:Number
The duration, in seconds, of the animation when the selected item is changed by keyboard navigation and the item scrolls into view.

list.keyScrollDuration = 0.5;
The default value is 0.25
.
