alternatingItemColors | 類型: Array 格式: Color CSS 繼承: 是 語言版本: ActionScript 3.0 產品版本: Flex 3 執行階段版本: Flash9, AIR 1.1 The colors to use for the backgrounds of the items in the list. The value is an array of two or more colors. The backgrounds of the list items alternate among the colors in the array. For DataGrid controls, all items in a row have the same background color, and each row's background color is determined from the array of colors. For the TileList control, which uses a single list to populate a two-dimensional display, the style can result in a checkerboard appearance, stripes, or other patterns based on the number of columns and rows and the number of colors specified. TileList cycles through the colors, placing the individual item background colors according to the layout direction. If you have an even number of colors and an even number of columns for a TileList layed out horizontally, you will get striping. If the number of columns is an odd number, you will get a checkerboard pattern. Only takes effect if no undefined。 | AdvancedListBase | ||

protected var caretItemRenderer:IListItemRenderer| 語言版本: | ActionScript 3.0 |
| 產品版本: | Flex 3 |
| 執行階段版本: | Flash Player 9, AIR 1.1 |
The renderer for the item under the caret. In the selection model, there is an anchor, a caret and a highlighted item. When the mouse is being used for selection, the item under the mouse is highlighted as the mouse rolls over the item. When the mouse is clicked with no modifier keys (Shift or Control), the set of selected items is cleared and the item under the highlight is selected and becomes the anchor. The caret is unused in mouse selection.
If there is an anchor and another item is selected while using the Shift key, the old set of selected items is cleared, and all items between the item and the anchor are selected. Clicking items while using the Control key toggles the selection of individual items and does not move the anchor.
When selecting items using the keyboard, if the arrow keys are used with no modifier keys, the old selection is cleared and the new item is selected and becomes the anchor and the caret, and a caret indicator is shown around the selection highlight.
If the user uses arrow keys with the Shift key, the old selection is cleared and the items between the anchor and the new item are selected. The caret moves to the new item.
If arrow keys are used with the Control key, just the caret moves. The user can use the Space key to toggle selection of the item under the caret.

An ICollectionView that represents the data provider.
When you set the dataProvider property,
Flex wraps the data provider as necessary to
support the ICollectionView interface and
sets this property to the result.
The AdvancedListBase class then uses this property to access
data in the provider.
When you get the dataProvider property,
Flex returns this value.
columnCount | 屬性 |

data:Object| 語言版本: | ActionScript 3.0 |
| 產品版本: | Flex 3 |
| 執行階段版本: | Flash Player 9, AIR 1.1 |
The item in the data provider this component should render when this component is used as an item renderer or item editor. The list class sets this property on each renderer or editor and the component displays the data. ListBase-derived classes support this property for complex situations like having a List of DataGrids or a DataGrid where one column is a List.
The list classes use the listData property
in addition to the data property to determine what
to display.
If the list class is in a DataGrid it expects the dataField
property of the column to map to a property in the data
and sets selectedItem value to that property.
If it is in a List or TileList control, it expects the
labelField property of the list to map to a property
in the data, and sets selectedItem value to that property.
Otherwise it sets the selectedItem to the data itself.
This property uses the data provider but does not set it. In all cases, you must set the data provider in some other way.
You do not set this property in MXML.

dataProvider:Object| 語言版本: | ActionScript 3.0 |
| 產品版本: | Flex 3 |
| 執行階段版本: | Flash Player 9, AIR 1.1 |
Set of data to be viewed.
This property lets you use most types of objects as data providers.
If you set the dataProvider property to an Array,
it will be converted to an ArrayCollection. If you set the property to
an XML object, it will be converted into an XMLListCollection with
only one item. If you set the property to an XMLList, it will be
converted to an XMLListCollection.
If you set the property to an object that implements the
IList or ICollectionView interface, the object will be used directly.
As a consequence of the conversions, when you get the
dataProvider property, it will always be
an ICollectionView, and therefore not necessarily be the type of object
you used to you set the property.
This behavior is important to understand if you want to modify the data
in the data provider: changes to the original data may not be detected,
but changes to the ICollectionView object that you get back from the
dataProvider property will be detected.

User-supplied function to run on each item to determine its dataTip.
By default, the list looks for a property named label
on each data provider item and displays it.
However, some items do not have a label property
nor do they have another property that can be used for displaying
in the rows. An example is a data set that has lastName and firstName
fields, but you want to display full names. You can supply a
dataTipFunction that finds the appropriate
fields and return a displayable string. The
dataTipFunction is also good for handling formatting
and localization.
The dataTipFunction takes a single argument which is the item in the data provider and returns a String:

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.

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 dragOver, and call the DragEvent's
preventDefault() method to customize
the way the list class accepts dropped data.
When you set dropEnabled to true,
Flex automatically calls the showDropFeedback()
and hideDropFeedback() methods to display the drop indicator.

| 產品版本: | Flex 3 |
| 執行階段版本: | Flash Player 9, AIR 1.1 |
The name of the field in the data provider object that determines what to display as the icon. By default, the list class does not try to display icons with the text in the rows. However, by specifying an icon field, you can specify a graphic that is created and displayed as an icon in the row. This property is ignored by DataGrid.
The renderers will look in the data provider object for a property of the name supplied as the iconField. If the value of the property is a Class, it will instantiate that class and expect it to be an instance of an IFlexDisplayObject. If the value of the property is a String, it will look to see if a Class exists with that name in the application, and if it can't find one, it will also look for a property on the document with that name and expect that property to map to a Class.

When a component is used as a drop-in item renderer or drop-in
item editor, Flex initializes the listData property
of the component with the additional data from the list control.
The component can then use the listData property
and the data property to display the appropriate
information as a drop-in item renderer or drop-in item editor.
You do not set this property in MXML or ActionScript; Flex sets it when the component is used as a drop-in item renderer or drop-in item editor.

| 執行階段版本: | Flash Player 9, AIR 1.1 |
Determines the UID for a data provider item. All items in a data provider must either have a unique ID (UID) or one will be generated and associated with it. This means that you cannot have an object or scalar value appear twice in a data provider.
For example, the following data provider is not supported because the value "foo" appears twice and the UID for a string is the string itself:
var sampleDP:Array = ["foo", "bar", "foo"]
Simple dynamic objects can appear twice if they are two separate instances. The following is supported because each of the instances will be given a different UID because they are different objects:
var sampleDP:Array = [{label: "foo"}, {label: "foo"}]
Note that the following is not supported because the same instance appears twice:
var foo:Object = {label: "foo"};
sampleDP:Array = [foo, foo];
參數
data:Object — The data provider item.
|
String — The UID as a string.
