alternatingItemColors | Tipo: Array Formato: Color Herança de CSS: Sim Versão da linguagem: ActionScript 3.0 Versão de produto: Flex 3 Versões de runtime: Flash9, AIR 1.1 The colors to use for the backgrounds of the items in the list. The value is an array of one 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. O valor padrão é undefined. | ListBase | ||

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 Ctrl), 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 Ctrl 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 Ctrl key, just the caret moves. The user can use the Space key to toggle selection of the item under the caret.

| Versão de produto: | Flex 3 |
| Versões de runtime: | 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 | propriedade |
dataProvider:Object| Versão da linguagem: | ActionScript 3.0 |
| Versão de produto: | Flex 3 |
| Versões de runtime: | 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.
O valor padrão é null.

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, as the following example shows:

labelFunction:Function| Versão da linguagem: | ActionScript 3.0 |
| Versão de produto: | Flex 3 |
| Versões de runtime: | Flash Player 9, AIR 1.1 |
A user-supplied function to run on each item to determine its label.
By default, the list looks for a property named label
on each data provider item and displays it.
However, some data sets do not have a label property
nor do they have another property that can be used for displaying.
An example is a data set that has lastName and firstName fields
but you want to display full names.
You can supply a labelFunction that finds the
appropriate fields and returns a displayable string. The
labelFunction is also good for handling formatting and
localization.
For most components, the label function takes a single argument which is the item in the data provider and returns a String.
myLabelFunction(item:Object):String
The method signature for the DataGrid and DataGridColumn classes is:
myLabelFunction(item:Object, column:DataGridColumn):String
where item contains the DataGrid item object, and
column specifies the DataGrid column.
O valor padrão é null.

offscreenExtraRowsOrColumns:int| Versão da linguagem: | ActionScript 3.0 |
| Versão de produto: | Flex 3 |
| Versões de runtime: | Flash Player 9, AIR 1.1 |
The target number of extra rows or columns of item renderers to be used in the layout of the control. Half of these rows/columns are created above or to the left of the visible onscreen rows/columns; half are created below or to the right.
Whether rows or columns are created is dependent on the control and its
properties. Generally rows will be used, except for TileBase components
where direction is set to TileBaseDirection.VERTICAL.
In that case, columns are created.
You set this property to a non-zero value primarily when applying data effects to the List or TileList controls. Changes that affect the data provider element corresponding to the currently visible items, or changes that affect the data provider element for the specified number of items before or after the visible items, trigger the data effect. Data provider elements outside this range may not be animated perfectly by the data effect.
This property is useful because data effects work by first determining a 'before' layout of the list-based control, then determining an 'after' layout, and finally setting the properties of the effect to create an animation from the before layout to the after layout. Since many effects cause currently invisible items to become visible, or currently visible items to become invisible, this property configures the control to create the offscreen item renderers so that they already exist when the data effect plays.
A reasonable value for this property might be the number of rows visible onscreen. Setting it to a very large value may cause performance problems when used with a data provider that contains a large number of elements.
O valor padrão é 0.

|---|---|
bubbles | false |
cancelable | false |
columnIndex | The zero-based index of the column associated with the event. |
currentTarget | The Object that defines the

myButton.addEventListener() to register an event listener,
myButton is the value of the currentTarget. |
