protected var collection:ICollectionView| 語言版本: | ActionScript 3.0 |

The ICollectionView of items this component displays.
dataProvider | 屬性 |
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 |
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.

If true keyboard input will be entered in the
editable text field; otherwise it will be used as shortcuts to

The flash.system.IMEConversionMode class defines constants for the
valid values for this property.
You can also specify null to specify no IME.

selectedIndex | 屬性 |
selectedIndex:int| 語言版本: | ActionScript 3.0 |

| 執行階段版本: | Flash Player 9, AIR 1.1 |
The index in the data provider of the selected item.
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
into the text field.
Unlike many other Flex properties that are invalidating (setting
them does not have an immediate effect), the selectedIndex and
selectedItem properties are synchronous; setting one immediately
affects the other.
預設值為 -1。

The item in the data provider at the selectedIndex.
If the data is an object or class instance, modifying
properties in the object or instance modifies the
dataProvider object but may not update the views
unless the instance is Bindable or implements IPropertyChangeNotifier
or a call to dataProvider.itemUpdated() occurs.
selectedItem property causes the
ComboBox control to select that item (display it in the text field and
set the selectedIndex) if it exists in the data provider.
If the ComboBox control is editable, the selectedItem
property is null if the user types any text
into the text field.
Unlike many other Flex properties that are invalidating (setting

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.
