The List control displays a vertical list of items. Its functionality is very similar to that of the SELECT form element in HTML. If there are more items than can be displayed at once, it can display a vertical scroll bar so the user can access all items in the list. An optional horizontal scroll bar lets the user view items when the full width of the list items is unlikely to fit. The user can select one or more items from the list, depending on the value of the
allowMultipleSelection property.
The List control has the following default sizing characteristics:
| Characteristic | Description |
|---|---|
| Default size | Wide enough to fit the widest label in the first seven visible items (or all visible items in the list, if there are less than seven); seven rows high, where each row is 20 pixels high. |
| Minimum size | 0 pixels. |
| Maximum size | 5000 by 5000. |

A reference to the currently active instance of the item editor, if it exists.
To access the item editor instance and the new item value when an
item is being edited, you use the itemEditorInstance
property. The itemEditorInstance property
is not valid until after the event listener for
the itemEditBegin event executes. Therefore, you typically
only access the itemEditorInstance property from within
the event listener for the itemEditEnd event.
The itemEditor property defines the
class of the item editor
and, therefore, the data type of the item editor instance.
You do not set this property in MXML.

| Versión de producto: | Flex 3 |
| Versiones de motor de ejecución: | Flash Player 9, AIR 1.1 |
Creates the item editor for the item renderer at the
editedItemPosition using the editor
specified by the itemEditor property.
This method sets the editor instance as the
itemEditorInstance property.
You can call this method only from within the event listener
for the itemEditBegin event. To create an editor
at other times, set the editedItemPosition property
to generate the itemEditBegin event.
Parámetros
colIndex:int — The column index. Flex sets the value of this property to 0 for a List control.
| |
rowIndex:int — The index in the data provider of the item to be
edited.

drawRowBackground | () | método |
protected function drawRowBackground(s:Sprite, rowIndex:int, y:Number, height:Number, color:uint, dataIndex:int):void| Versión del lenguaje: | ActionScript 3.0 |
| Versión de producto: | Flex 3 |
| Versiones de motor de ejecución: | Flash Player 9, AIR 1.1 |
Draws a row background
at the position and height specified. This creates a Shape as a
child of the input Sprite and fills it with the appropriate color.
This method also uses the backgroundAlpha style property
setting to determine the transparency of the background color.
Parámetros
s:Sprite — A Sprite that will contain a display object
that contains the graphics for that row.
| |
rowIndex:int — The row's index in the set of displayed rows. The
header does not count; the top most visible row has a row index of 0.
This is used to keep track of the objects used for drawing
backgrounds so that a particular row can reuse the same display object
even though the index of the item that the row is rendering has changed.
| |
y:Number — The suggested y position for the background.
| |
height:Number — The suggested height for the indicator.
| |
color:uint — The suggested color for the indicator.
| |

of copying the edited data from
the itemEditorInstance to the data provider and hiding the
itemEditorInstance.
Parámetros
reason:String — A constant defining the reason for the event
(such as "CANCELLED", "NEW_ROW", or "OTHER").
The value must be a member of the ListEventReason class.

Dispatched when the editedItemPosition property is set
and the item can be edited.
type property of the event object for a
itemEditBegin event, which indicates that an
item is ready to be edited.
The default listener for this event performs the following actions:
- Creates an item editor object via a call to the
createItemEditor()method. - Copies the
dataproperty from the item to the editor. By default, the item editor object is an instance of the TextInput control. You use theitemEditorproperty of the list control to specify a custom item editor class. - Set the
itemEditorInstanceproperty of the list control to reference the item editor instance.
You can write an event listener for this event to modify the data passed to the item editor. For example, you might modify the data, its format, or other information used by the item editor.
You can also create an event listener to specify the item editor used to edit the item. For example, you might have two different item editors. Within the event listener you can examine the data to be edited or other information, and open the appropriate item editor by doing the following:
- Call
preventDefault()to stop Flex from calling thecreateItemEditor()method as part of the default event listener. - Set the
itemEditorproperty to the appropriate editor. - Call the
createItemEditor()method.
The properties of the event object have the following values:
| Property | Value |
|---|---|
bubbles | false |
cancelable | true |
columnIndex | The zero-based index of the column associated with the event. |
currentTarget | The Object that defines the
event listener that handles the event. For example, if you use
myButton.addEventListener() to register an event listener,
myButton is the value of the currentTarget. |
itemRenderer | The item renderer for the item that is being edited. |
reason | null |
rowIndex | The zero-based index of the item associated with the event. |
target | The Object that dispatched the event;
it is not always the Object listening for the event.
Use the currentTarget property to always access the

Dispatched when the user releases the mouse button while over an item, tabs to the List or within the List, or in any other way attempts to edit an item.
The ListEvent.ITEM_EDIT_BEGINNING constant defines the value of thetype property of the ListEvent object for a
itemEditBeginning event, which indicates that the user has
prepared to edit an item, for example, by releasing the mouse button
over the item.
The default listener for this event sets the List.editedItemPosition
property to the item that has focus, which starts the item editing session.
You typically write your own event listener for this event to
disallow editing of a specific item or items.
Calling the preventDefault() method from within your own
event listener for this event prevents the default listener from executing.
The properties of the event object have the following values:
| Property | Value |
|---|---|
bubbles | false |
cancelable | true |
columnIndex | The zero-based index of the column associated with the event. |
currentTarget | The Object that defines the
event listener that handles the event. For example, if you use
myButton.addEventListener() to register an event listener,
myButton is the value of the currentTarget. |
itemRenderer | The item renderer for the item that will be edited. This property is null if this event is generated by keyboard, as the item to be edited may be off-screen. |
reason | null |
rowIndex | The zero-based index of the item associated with the event. |

Dispatched when an item editing session is ending for any reason.
The ListEvent.ITEM_EDIT_END constant defines the value of thetype property of the ListEvent object for a
itemEditEnd event, which indicates that an edit
session is ending.
The list components have a default handler for this event that copies the data from the item editor to the data provider of the list control. The default event listener performs the following actions:
- Uses the
editorDataFieldproperty of the list control to determine the property of the item editor containing the new data and updates the data provider item with that new data. Since the default item editor is the TextInput control, the default value of theeditorDataFieldproperty is"text", to specify that thetextproperty of the TextInput contains the new item data. - Calls the
destroyItemEditor()method to close the item editor.
You typically write an event listener for this event to perform the following actions:
- In your event listener, you can modify the data returned by the editor
to the list component. For example, you can reformat the data before returning
it to the list control. By default, an item editor can only return a single value.
You must write an event listener for the
itemEditEndevent if you want to return multiple values. - In your event listener, you can examine the data entered into the item editor.
If the data is incorrect, you can call the
preventDefault()method to stop Flex from passing the new data back to the list control and from closing the editor.
The properties of the event object have the following values:
| Property | Value |
|---|---|
bubbles | false |

reason | A constant defining the reason for the event.
The value must be a member of the ListEventReson class. |
