allowMultipleSelection property.
Note: The Spark list-based controls (the Spark ListBase class and its subclasses
such as ButtonBar, ComboBox, DropDownList, List, and TabBar) do not support the BasicLayout class
as the value of the layout property.
Do not use BasicLayout with the Spark list-based controls. When a layout is specified,
the layout's typicalLayoutElement property should not be set; it's automatically set
to an item renderer created with the List's typicalItem.
To use this component in a list-based component, such as a List or DataGrid, create an item renderer. For information about creating an item renderer, see Custom Spark item renderers.
The List control has the following default characteristics:
| Characteristic | Description |
|---|---|
| Default size | 112 pixels wide by 112 pixels high |
| Minimum size | 112 pixels wide by 112 pixels high |
| Maximum size | 10000 pixels wide and 10000 pixels high |
| Default skin class | spark.skins.spark.ListSkin |

屬性詳細資訊
allowMultipleSelection | 屬性 |
allowMultipleSelection:Boolean| 語言版本: | ActionScript 3.0 |
| 產品版本: | Flex 4 |
| 執行階段版本: | Flash Player 10, AIR 1.5 |
If true multiple selection is enabled.
When switched at run time, the current selection
is cleared.
This should not be turned on when interactionMode
is touch.
預設值為 false。
實作
public function get allowMultipleSelection():Boolean public function set allowMultipleSelection(value:Boolean):voiddragEnabled | 屬性 |
dragEnabled:Boolean| 語言版本: | ActionScript 3.0 |
| 產品版本: | Flex 4 |
| 執行階段版本: | Flash Player 10, AIR 1.5 |
A flag that indicates whether you can drag items out of
this control and drop them on other controls.
If true, dragging is enabled for the control.
If the dropEnabled property is also true,
you can drag items and drop them within this control
to reorder the items.
Drag and drop is not supported on mobile devices where
interactionMode is set to touch.
預設值為 false。
實作
public function get dragEnabled():Boolean public function set dragEnabled(value:Boolean):voiddragMoveEnabled | 屬性 |
dragMoveEnabled:Boolean| 語言版本: | ActionScript 3.0 |
| 產品版本: | Flex 4 |
| 執行階段版本: | Flash Player 10, AIR 1.5 |
A flag that indicates whether items can be moved instead
of just copied from the control as part of a drag-and-drop
operation.
If true, and the dragEnabled property
is true, items can be moved.
Often the data provider cannot or should not have items removed
from it, so a MOVE operation should not be allowed during
drag-and-drop.
Drag and drop is not supported on mobile devices where
interactionMode is set to touch.
預設值為 false。
實作
public function get dragMoveEnabled():Boolean public function set dragMoveEnabled(value:Boolean):voiddropEnabled | 屬性 |
dropEnabled:Boolean| 語言版本: | ActionScript 3.0 |
| 產品版本: | Flex 4 |
| 執行階段版本: | Flash Player 10, AIR 1.5 |
A flag that indicates whether dragged items can be dropped onto the control.
If you set this property to true,
the control accepts all data formats, and assumes that
the dragged data matches the format of the data in the data provider.
If you want to explicitly check the data format of the data
being dragged, you must handle one or more of the drag events,
such as dragEnter and dragOver,
and call the DragEvent's preventDefault() method
to customize the way the list class accepts dropped data.
Drag and drop is not supported on mobile devices where
interactionMode is set to touch.
預設值為 false。
實作
public function get dropEnabled():Boolean public function set dropEnabled(value:Boolean):voidhasFocusableChildren | 屬性 |
hasFocusableChildren:Boolean[覆寫] | 語言版本: | ActionScript 3.0 |
| 產品版本: | Flex 4 |
| 執行階段版本: | Flash Player 10, AIR 1.5 |
A flag that indicates whether this List's focusable item renderers can take keyboard focus.
Note: This property is similar to the tabChildren property
used by Flash Player.
Use the hasFocusableChildren property with Flex applications.
Do not use the tabChildren property.
This property is usually false because most components
either receive focus themselves or delegate focus to a single
internal sub-component and appear as if the component has
received focus. You may choose to set this to true on a List
such that the contents within your List become focusable.
If set, and the List skin contains a Scroller skin part, the value is proxied down onto the Scroller.
If the value is true, this proxying means that
the contents of the Scroller, like item renderers, are now
focusable. For example, this means the first tab keystroke will
put focus on the List control, and the second tab keystroke will
put focus on the first focusable child of the Scroller.
If false, the first tab keystroke will put focus
on the List control and the second tab keystroke will move focus
to the next focusable control after the List.
預設值為 false。

scrollSnappingMode:String| 語言版本: | ActionScript 3.0 |
| 產品版本: | Flex 4.6 |
| 執行階段版本: | AIR 3 |
The scroll snapping mode currently in effect for this Scroller
Changing this property to anything other than "none" may result in an immediate change in scroll position to ensure an element is correctly "snapped" into position. This change in scroll position is not animated
預設值為 "none"。

selectedIndices | 屬性 |
selectedIndices:Vector.<int>| 語言版本: | ActionScript 3.0 |

| 執行階段版本: | Flash Player 10, AIR 1.5 |
A Vector of ints representing the indices of the currently selected
item or items.
If multiple selection is disabled by setting
allowMultipleSelection to false, and this property
is set, the data item corresponding to the first index in the Vector is selected.
If multiple selection is enabled by setting
allowMultipleSelection to true, this property
contains a list of the selected indices in the reverse order in which they were selected.
That means the first element in the Vector corresponds to the last item selected.
預設值為 []。
此屬性可以做為資料繫結的來源。一旦修改此屬性，將傳送 valueCommit 事件。

| 執行階段版本: | Flash Player 10, AIR 1.5 |
A Vector of Objects representing the currently selected data items.
If multiple selection is disabled by setting allowMultipleSelection
to false, and this property is set, the data item
corresponding to the first item in the Vector is selected.
If multiple selection is enabled by setting
allowMultipleSelection to true, this property
contains a list of the selected items in the reverse order in which they were selected.
That means the first element in the Vector corresponds to the last item selected.

| 執行階段版本: | Flash Player 10, AIR 1.5 |
Sets the value of the useVirtualLayout property
of the layout associated with this control.
If the layout is subsequently replaced and the value of this
property is true, then the new layout's
useVirtualLayout property is set to true.
預設值為 true。
