Implements IItemRendererOwner

Language Version : ActionScript 3.0
Product Version : Flex 4
Runtime Versions : Flash Player 10, AIR 1.5

The DataGroup class is the base container class for data items. The DataGroup class converts data items to visual elements for display. While this container can hold visual elements, it is often used only to hold data items as children.

The DataGroup class takes as children data items or visual elements that implement the IVisualElement interface and are DisplayObjects. Data items can be simple data items such String and Number objects, and more complicated data items such as Object and XMLNode objects. While these containers can hold visual elements, they are often used only to hold data items as children.

An item renderer defines the visual representation of the data item in the container. The item renderer converts the data item into a format that can be displayed by the container. You must pass an item renderer to a DataGroup container to render data items appropriately.

To improve performance and minimize application size, the DataGroup container cannot be skinned. If you want to apply a skin, use the SkinnableDataContainer instead.

The DataGroup container has the following default characteristics:

CharacteristicDescription
Default sizeLarge enough to display its children
Minimum size0 pixels
Maximum size10000 pixels wide and 10000 pixels high

Property Detail
baselinePositionproperty
baselinePosition:Number  [read-only] [override]

Language Version : ActionScript 3.0
Product Version : Flex 4
Runtime Versions : Flash Player 10, AIR 1.5

The y-coordinate of the baseline of the first line of text of the component.

This property is used to implement the baseline constraint style. It is also used to align the label of a FormItem with the controls in the FormItem.

Each component should override this property.


Implementation
    public function get baselinePosition():Number
dataProviderproperty 
dataProvider:IList

Language Version : ActionScript 3.0
Product Version : Flex 4
Runtime Versions : Flash Player 10, AIR 1.5

The data provider for this DataGroup. It must be an IList.

There are several IList implementations included in the Flex framework, including ArrayCollection, ArrayList, and XMLListCollection.

The default value is null.

This property can be used as the source for data binding.


Implementation
    public function get dataProvider():IList
    public function set dataProvider(value:IList):void

See also

itemRendererproperty 
itemRenderer:IFactory

Language Version : ActionScript 3.0
Product Version : Flex 4
Runtime Versions : Flash Player 10, AIR 1.5

The item renderer to use for data items. The class must implement the IDataRenderer interface. If defined, the itemRendererFunction property takes precedence over this property.

The default value is null.


Implementation
    public function get itemRenderer():IFactory
    public function set itemRenderer(value:IFactory):void
itemRendererFunctionproperty 
itemRendererFunction:Function

Language Version : ActionScript 3.0
Product Version : Flex 4
Runtime Versions : Flash Player 10, AIR 1.5

Function that returns an item renderer IFactory for a specific item. You should define an item renderer function similar to this sample function:

        function myItemRendererFunction(item:Object):IFactory

Currently, when using itemRendererFunction with a virtual layout (useVirtualLayout=true), item renderer recycling is turned off. Because of this, using itemRendererFunction can cause a performance degredation and is not recommended for mobile. This may be fixed in future versions of Flex.

The default value is null.


Implementation
    public function get itemRendererFunction():Function
    public function set itemRendererFunction(value:Function):void
typicalItemproperty 
typicalItem:Object

Language Version : ActionScript 3.0
Product Version : Flex 4
Runtime Versions : Flash Player 10, AIR 1.5

Layouts use the preferred size of the typicalItem when fixed row or column sizes are required, but a specific rowHeight or columnWidth value is not set. Similarly virtual layouts use this item to define the size of layout elements that have not been scrolled into view.

The container uses the typical data item, and the associated item renderer, to determine the default size of the container children. By defining the typical item, the container does not have to size each child as it is drawn on the screen.

Setting this property sets the typicalLayoutElement property of the layout.

Restriction: if the typicalItem is an IVisualItem, it must not also be a member of the data Provider.

The default value is null.


Implementation
    public function get typicalItem():Object
    public function set typicalItem(value:Object):void
Constructor Detail
DataGroup()Constructor
public function DataGroup()

Language Version : ActionScript 3.0
Product Version : Flex 4
Runtime Versions : Flash Player 10, AIR 1.5

Constructor.

Method Detail
getItemIndicesInView()method
public function getItemIndicesInView():Vector.<int>

Language Version : ActionScript 3.0
Product Version : Flex 4.5
Runtime Versions : Flash Player 10, AIR 2.5

Return the indices of the item renderers visible within this DataGroup.

If clipAndEnableScrolling is true, return the indices of the visible = true ItemRenderers that overlap this DataGroup's scrollRect. That is, the ItemRenders that are at least partially visible relative to this DataGroup. If clipAndEnableScrolling is false, return a list of integers from 0 to dataProvider.length - 1. Note that if this DataGroup's owner is a Scroller, then clipAndEnableScrolling has been set to true.

The corresponding item renderer for each returned index can be retrieved with the getElementAt() method, even if the layout is virtual

The order of the items in the returned Vector is not guaranteed.

Note that the VerticalLayout and HorizontalLayout classes provide bindable firstIndexInView and lastIndexInView properties which contain the same information as this method.

Returns
Vector.<int> — The indices of the visible item renderers.
itemToLabel()method 
public function itemToLabel(item:Object):String

Language Version : ActionScript 3.0
Product Version : Flex 4.5
Runtime Versions : Flash Player 10, AIR 2.5

Given a data item, return the toString() representation of the data item for an item renderer to display. Null data items return the empty string.

Returns the String for display in an item renderer. The String is written to the labelText property of the item renderer.

Parameters

item:Object — The data item to display.

Returns
String — The String for display in an item renderer.
updateRenderer()method 
public function updateRenderer(renderer:IVisualElement, itemIndex:int, data:Object):void

Language Version : ActionScript 3.0
Product Version : Flex 4.5
Runtime Versions : Flash Player 10, AIR 2.5

Updates the renderer for reuse. This method first prepares the item renderer for reuse by cleaning out any stale properties as well as updating it with new properties.

The last thing this method should do is set the data property of the item renderer.

Parameters

renderer:IVisualElement — The item renderer.
 
itemIndex:int — The index of the data in the data provider.
 
data:Object — The data object this item renderer is representing.

Event Detail
rendererAdd Event

RendererExistenceEvent.type property = spark.events.RendererExistenceEvent.RENDERER_ADD

Language Version : ActionScript 3.0

Runtime Versions : Flash Player 10, AIR 1.5

Dispatched when a renderer is added to this dataGroup. event.renderer is the renderer that was added.

The RendererExistenceEvent.RENDERER_ADD constant defines the value of the type property of the event object for an rendererAdd event.

The properties of the event object have the following values:

PropertyValue
