dataProvider | propiedad |
dataProvider:Object| Versión del lenguaje: | ActionScript 3.0 |
| Versión de producto: | Flex 3 |
| Versiones de motor de ejecución: | Flash Player 9, AIR 1.1 |
The set of items this component displays. This property is of type Object because the derived classes can handle a variety of data types such as Arrays, XML, ICollectionViews, and other classes. All are converted into an ICollectionView and that ICollectionView is returned if you get the value of this property; you will not get the value you set if it was not an ICollectionView.
Setting this property will adjust the selectedIndex
property (and therefore the selectedItem property) if
the selectedIndex property has not otherwise been set.
If there is no prompt property, the selectedIndex
property will be set to 0; otherwise it will remain at -1,
the index used for the prompt string.
If the selectedIndex property has been set and
it is out of range of the new data provider, unexpected behavior is
likely to occur.

A flag that indicates whether the control is editable, which lets the user directly type entries that are not specified in the dataProvider, or not editable, which requires the user select from the items in the dataProvider.
If true keyboard input will be entered in the
editable text field; otherwise it will be used as shortcuts to

If there is a prompt property, the selectedIndex
value can be set to -1 to show the prompt.
If there is no prompt, property then selectedIndex
will be set to 0 once a dataProvider is set.
If the ComboBox control is editable, the selectedIndex
property is -1 if the user types any text

Unlike many other Flex properties that are invalidating (setting
them does not have an immediate effect), the selectedIndex and

Determines default values of the height and width to use for the
entries in the drop-down list.
Each subclass of ComboBase must implement this method and return
an Object containing two properties: width and
height.
Parámetros
numItems:int — The number of items to check to determine the size.
|
Object — An Object with width and height
properties.

collectionChangeHandler | () | método |
protected function collectionChangeHandler(event:Event):void| Versión del lenguaje: | ActionScript 3.0 |
| Versión de producto: | Flex 3 |

Responds to changes to the data provider. The component will adjust
the selectedIndex property if items are added or removed
before the component's selected item.
Parámetros
event:Event — The CollectionEvent dispatched from the collection.

Performs some action when the drop-down button is pressed. This is an abstract base class implementation, so it has no effect and is overridden by the subclasses.
Parámetros
event:FlexEvent — The event that is triggered when the drop-down button is pressed.

protected function itemToUID(data:Object):String| Versión del lenguaje: | ActionScript 3.0 |

measure | () | método |
override protected function measure():void| Versión del lenguaje: | ActionScript 3.0 |
| Versión de producto: | Flex 3 |
| Versiones de motor de ejecución: | Flash Player 9, AIR 1.1 |
Determines the measuredWidth and
measuredHeight properties of the control.
The measured width is the width of the widest text
in the dataProvider
plus the width of the drop-down button.
The measured height is the larger of either the button or the text.
If no data provider has been set or there are no items
in the data provider, the measuredWidth property is set to
UIComponent.DEFAULT_MEASURED_WIDTH and the
measuredHeight property is set
to UIComponent.DEFAULT_MEASURED_HEIGHT.

Parámetros
unscaledWidth:Number — Specifies the width of the component, in pixels,
in the component's coordinates, regardless of the value of the
scaleX property of the component.
| |
unscaledHeight:Number — Specifies the height of the component, in pixels,
in the component's coordinates, regardless of the value of the
scaleY property of the component.
