Med början från Flex 4.0, rekommenderar Adobe att du använder klassen spark.components.List som ett alternativ till den här klassen.
The layout-specific List components in Flex 3 have been replaced by a more generic
List component that takes a generic layout. To get similar behavior from the new
List component, set the |
The HorizontalList control displays a horizontal list of items. If there are more items than can be displayed at once, it can display a horizontal scroll bar so the user can access all items in the list.
The HorizontalList control has the following default sizing characteristics:
Characteristic | Description |
---|---|
Default size | Four columns, with size determined by the cell dimensions. |
Minimum size | 0 pixels. |
Maximum size | 5000 by 5000. |
The <mx:HorizontalList>
tag inherits all of the
tag attributes of its superclass and it adds no new tag attributes.
