 | Because this component does not define a skin for the mobile theme, Adobe recommends that you not use it in a mobile application. Alternatively, you can define your own mobile skin for the component. For more information, see Basics of mobile skinning. |
The DropDownList control contains a drop-down list from which the user can select a single value. Its functionality is very similar to that of the SELECT form element in HTML.
The DropDownList control consists of the anchor button, prompt area, and drop-down-list, Use the anchor button to open and close the drop-down-list. The prompt area displays a prompt String, or the selected item in the drop-down-list.
When the drop-down list is open:
- Clicking the anchor button closes the drop-down list and commits the currently selected data item.
- Clicking outside of the drop-down list closes the drop-down list and commits the currently selected data item.
- Clicking on a data item selects that item and closes the drop-down list.
- If the
requireSelectionproperty isfalse, clicking on a data item while pressing the Control key deselects the item and closes the drop-down list.
Note: The Spark list-based controls (the Spark ListBase class and its subclasses
such as ButtonBar, ComboBox, DropDownList, List, and TabBar) do not support the BasicLayout class
as the value of the layout property.
Do not use BasicLayout with the Spark list-based controls.
To use this component in a list-based component, such as a List or DataGrid, create an item renderer. For information about creating an item renderer, see Custom Spark item renderers.
The DropDownList control has the following default characteristics:
| Characteristic | Description |
|---|---|
| Default size | 112 pixels wide and 21 pixels high |
| Minimum size | 112 pixels wide and 21 pixels high |
| Maximum size | 10000 pixels wide and 10000 pixels high |
| Default skin class | spark.skins.spark.DropDownListSkin |

prompt | 속성 |
prompt:String| 언어 버전: | ActionScript 3.0 |
| 제품 버전: | Flex 4 |
| 런타임 버전: | Flash Player 10, AIR 1.5 |
The prompt for the DropDownList control.
The prompt is a String that is displayed in the
DropDownList when selectedIndex = -1.
It is usually a String such as "Select one...".
Selecting an item in the drop-down list replaces the
prompt with the text from the selected item.
기본값: "".
구현

typicalItem:Object[재정의] | 언어 버전: | ActionScript 3.0 |
| 제품 버전: | Flex 4 |
| 런타임 버전: | Flash Player 10, AIR 1.5 |
Layouts use the preferred size of the typicalItem
when fixed row or column sizes are required, but a specific
rowHeight or columnWidth value is not set.
Similarly virtual layouts use this item to define the size
of layout elements that have not been scrolled into view.
The container uses the typical data item, and the associated item renderer, to determine the default size of the container children. By defining the typical item, the container does not have to size each child as it is drawn on the screen.
Setting this property sets the typicalLayoutElement property
of the layout.
Restriction: if the typicalItem is an IVisualItem, it must not
also be a member of the data provider.
Note: Setting typicalItem overrides any explicit width or height
set on the labelDisplay skin part.
기본값: null.
