dataProvider property.
Unlike the Menu and MenuBar controls, the PopUpMenuButton control
supports only a single-level menu. This means that the menu cannot contain
cascading submenus.
The main sub-button of the PopUpMenuButton control can have a
text label, an icon, or both on its face.
When a user selects an item from the drop-down menu or clicks
the main button of the PopUpMenuButton control, the control
dispatches an itemClick event.
When a user clicks the main button of the
control, the control also dispatches a click event.
You can customize the look of a PopUpMenuButton control.
The PopUpMenuButton control has the following sizing characteristics:
| Characteristic | Description |
|---|---|
| Default size | Sufficient to accommodate the label and any icon on the main button, and the icon on the pop-up button. The control does not reserve space for the menu. |
| Minimum size | 0 pixels. |
| Maximum size | 10000 by 10000. |

Property Detail
dataDescriptor | property |
dataDescriptor:IMenuDataDescriptor| Language Version: | ActionScript 3.0 |
| Product Version: | Flex 3 |
| Runtime Versions: | Flash Player 9, AIR 1.1 |
The data descriptor accesses and manipulates data in the data provider.
When you specify this property as an attribute in MXML, you must use a reference to the data descriptor, not the string name of the descriptor. Use the following format for the property:
<mx:PopUpMenuButton id="menubar" dataDescriptor="{new MyCustomDataDescriptor()}"/>
Alternatively, you can specify the property in MXML as a nested subtag, as the following example shows:
<mx:PopUpMenuButton>
<mx:dataDescriptor>
<myCustomDataDescriptor>
</mx:dataDescriptor>
...
The default value is an internal instance of the DefaultDataDescriptor class.
Implementation
public function get dataDescriptor():IMenuDataDescriptor public function set dataDescriptor(value:IMenuDataDescriptor):voiddataProvider | property |
dataProvider:Object| Language Version: | ActionScript 3.0 |
| Product Version: | Flex 3 |
| Runtime Versions: | Flash Player 9, AIR 1.1 |
DataProvider for popUpMenu.
The default value is null.
This property can be used as the source for data binding. When this property is modified, it dispatches the collectionChange event.
Implementation
public function get dataProvider():Object public function set dataProvider(value:Object):voidiconField | property |
iconField:String
Name of the field in the dataProvider Array that contains the icon to
show for each menu item.
The iconFunction property, if set, overrides this property.
The item renderer looks in the data provider for a property with
the name specified to the iconField property.
If the value of the property is a
Class, it instantiates that class and expect it to be an instance
of an IFlexDisplayObject. If the value of the property is a String,
it looks to see if a Class property exists with that name in the application.
If it can't find a property on the application, it looks for a property on the
document with that name and expect that property to map to a Class.
If the data provider is an E4X XML object, you must set this property
explicitly; for example, use @icon to specify the icon attribute.
The default value is "icon".
This property can be used as the source for data binding. When this property is modified, it dispatches the iconFieldChanged event.
Implementation
public function get iconField():String public function set iconField(value:String):voidiconFunction | property |
iconFunction:Function
A function that determines the icon to display for each menu item.
If you omit this property, Flex uses the contents of the field or attribute
determined by the iconField property.
If you specify this property, Flex ignores any iconField
property value.
By default, the menu does not try to display icons with the text in the rows. However, by specifying an icon function, you can specify a Class for a graphic that will be created and displayed as an icon in the row.
The iconFunction takes a single argument which is the item in the data provider and returns a Class:
The default value is null.
Implementation
public function get iconFunction():Function public function set iconFunction(value:Function):voidlabelField | property |
labelField:String| Language Version: | ActionScript 3.0 |
| Product Version: | Flex 3 |
| Runtime Versions: | Flash Player 9, AIR 1.1 |
Name of the field in the dataProvider Array that contains the text to
show for each menu item.
The labelFunction property, if set, overrides this property.
If the data provider is an Array of Strings, Flex uses each String
value as the label.
If the data provider is an E4X XML object, you must set this property
explicitly; for example, use @label to specify the label attribute.
The default value is "label".
This property can be used as the source for data binding. When this property is modified, it dispatches the labelFieldChanged event.
Implementation
public function get labelField():String public function set labelField(value:String):voidlabelFunction | property |
labelFunction:Function| Language Version: | ActionScript 3.0 |
| Product Version: | Flex 3 |
| Runtime Versions: | Flash Player 9, AIR 1.1 |
A function that determines the text to display for each menu item.
If you omit this property, Flex uses the contents of the field or attribute
determined by the labelField property.
If you specify this property, Flex ignores any labelField
property value.
If you specify this property, the label function must find the
appropriate field or fields and return a displayable string.
The labelFunction property is good for handling formatting
and localization.
The label function must take a single argument which is the item in the dataProvider and return a String, as the following example shows:
labelFunction(item:Object):String
The default value is null.
Implementation
public function get labelFunction():Function public function set labelFunction(value:Function):voidpopUp | property |
popUp:IUIComponent[override] | Language Version: | ActionScript 3.0 |
| Product Version: | Flex 3 |
| Runtime Versions: | Flash Player 9, AIR 1.1 |
A reference to the pop-up Menu object.
This property is read-only, and setting it has no effect.
Set the dataProvider property, instead.
(The write-only indicator appears in the syntax summary because the
property in the superclass is read-write and this class overrides
the setter with an empty implementation.)
Implementation
override public function get popUp():IUIComponent override public function set popUp(value:IUIComponent):voidshowRoot | property |
showRoot:Boolean| Language Version: | ActionScript 3.0 |
| Product Version: | Flex 3 |
| Runtime Versions: | Flash Player 9, AIR 1.1 |
Specifies whether to display the top-level node or nodes of the data provider.
If this is set to false, the control displays
only descendants of the first top-level node.
Any other top-level nodes are ignored.
You normally set this property to false for
E4X format XML data providers, where the top-level node is the document
object.
The default value is true.

mx.events.MenuEvent.ITEM_CLICK| Language Version: | ActionScript 3.0 |
| Product Version: | Flex 3 |
| Runtime Versions: | Flash Player 9, AIR 1.1 |
Dispatched when a user selects an item from the pop-up menu.
The MenuEvent.ITEM_CLICK event type constant indicates that the user selected a menu item.The properties of the event object for this event type have the following values. Not all properties are meaningful for all kinds of events. See the detailed property descriptions for more information.
| Property | Value |
|---|---|
bubbles | false |
cancelable | true |
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. |
index | The index in the menu of the selected menu item. |
item | The item in the dataProvider that was selected. |
itemRenderer | The ListItemRenderer of the selected menu item. |
label | The label text of the selected menu item. |
menu | The specific Menu instance associated with this event, or
null if a MenuBar item is dispatching the event. |
menuBar | The MenuBar instance that is the parent of the
Menu control, or null if the Menu control is not
parented by a MenuBar control. |
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
Object listening for the event. |
type | MenuEvent.ITEM_CLICK |
