listData
property implemented by drop-in item renderers or drop-in item editors
for the List control.
All drop-in item renderers and drop-in item editors must implement
the IDropInListItemRenderer interface, which defines
the listData property.
While the properties of this class are writable, you should consider them to be read only. They are initialized by the List class, and read by an item renderer or item editor. Changing these values can lead to unexpected results.

icon | property |
public var icon:Class| Language Version: | ActionScript 3.0 |
| Product Version: | Flex 3 |
| Runtime Versions: | Flash Player 9, AIR 1.1 |
A Class representing the icon for the item in the List control computed
from the list class's itemToIcon() method
This property can be used as the source for data binding. When this property is modified, it dispatches the __NoChangeEvent__ event.
labelField | property |
public var labelField:String| Language Version: | ActionScript 3.0 |
| Product Version: | Flex 3 |
| Runtime Versions: | Flash Player 9, AIR 1.1 |
The value of the labelField property in the list class.
This is the value normally used to calculate which property should
be taken from the item in the data provider for the text displayed
in the item renderer, but is also used by DateField and other
components to indicate which field to take from the data provider item
that contains a Date or other non-text property.
For example, if a data provider item contains a "hiredDate" property,
the labelField property can be set to "hiredDate"
and the itemRenderer property
can be set to DateField. The DateField control then uses the hiredDate
property.
This property can be used as the source for data binding. When this property is modified, it dispatches the __NoChangeEvent__ event.
