Like other Flex menu components, to define the structure of a menu represented by a
FlexNativeMenu component, you create a data provider such as an XML hierarchy or an array
of objects containing data to be used to define the menu. Several properties can be set to
define how the data provider data is interpreted, such as the labelField property
to specify the data field that is used for the menu item label, the keyEquivalentField
property to specify the field that defines a keyboard equivalent shortcut for the menu item,
and the mnemonicIndexField property to specify the field that defines the index
position of the character in the label that is used as the menu item's mnemonic.
The data provider for FlexNativeMenu items can specify several attributes that determine how the item is displayed and behaves, as the following XML data provider shows:
<mx:XML format="e4x" id="myMenuData">
<root>
<menuitem label="MenuItem A">
<menuitem label="SubMenuItem A-1" enabled="False"/>
<menuitem label="SubMenuItem A-2"/>
</menuitem>
<menuitem label="MenuItem B" type="check" toggled="true"/>
<menuitem label="MenuItem C" type="check" toggled="false"/>
<menuitem type="separator"/>
<menuitem label="MenuItem D">
<menuitem label="SubMenuItem D-1"/>
<menuitem label="SubMenuItem D-2"/>
<menuitem label="SubMenuItem D-3"/>
</menuitem>
</root>
</mx:XML>
The following table lists the attributes you can specify, their data types, their purposes, and how the data provider must represent them if the menu uses the DefaultDataDescriptor class to parse the data provider:
| Attribute | Type | Description |
|---|---|---|
altKey
| Boolean | Specifies whether the Alt key is required as part of the key equivalent for the item. |
cmdKey
| Boolean |
Note: this attribute is deprecated as of Flex 3.2. Use
commandKey instead. Specifies whether the Command key is required as part
of the key equivalent for the item. |
commandKey
| Boolean | Specifies whether the Command key is required as part of the key equivalent for the item. |
controlKey
| Boolean | Specifies whether the Control key is required as part of the key equivalent for the item. |
ctrlKey
| Boolean |
Note: this attribute is deprecated as of Flex 3.2. Use
controlKey instead. Specifies whether the Control key is required as part
of the key equivalent for the item. |
enabled
| Boolean | Specifies whether the user can select the menu item (true),
or not (false). If not specified, Flex treats the item as if
the value were true.
If you use the default data descriptor, data providers must use an enabled
XML attribute or object field to specify this characteristic. |
keyEquivalent
| String | Specifies a keyboard character which, when pressed, triggers an event as though
the menu item was selected. The menu's keyEquivalentField or
keyEquivalentFunction property determines the name of the field
in the data that specifies the key equivalent, or a function for determining
the key equivalents. (If the data provider is in E4X XML format, you must specify
one of these properties to assign a key equivalent.) |
label
| String | Specifies the text that appears in the control. This item is used for all
menu item types except separator.
The menu's labelField or labelFunction property
determines the name of the field in the data that specifies the label,
or a function for determining the labels. (If the data provider is in E4X XML format,
you must specify one of these properties to display a label.)
If the data provider is an Array of Strings, Flex uses the String value as the label. |
mnemonicIndex
| Integer | Specifies the index position of the character in the label that is used as the
mnemonic for the menu item. The menu's mnemonicIndexField or
mnemonicIndexFunction property determines the name of the field
in the data that specifies the mnemonic index, or a function for determining
mnemonic index. (If the data provider is in E4X XML format, you must specify
one of these properties to specify a mnemonic index in the data.) Alternatively,
you can indicate that a character in the label is the menu item's mnemonic by
including an underscore immediately to the left of that character. |
shiftKey
| Boolean | Specifies whether the Shift key is required as part of the key equivalent for the item. |
toggled
| Boolean | Specifies whether a check item is selected.
If not specified, Flex treats the item as if the value were false
and the item is not selected.
If you use the default data descriptor, data providers must use a toggled
XML attribute or object field to specify this characteristic. |
type
| String | Specifies the type of menu item. Meaningful values are separator and
check. Flex treats all other values,
or nodes with no type entry, as normal menu entries.
If you use the default data descriptor, data providers must use a type
XML attribute or object field to specify this characteristic. |
To create a window menu, set the FlexNativeMenu as the menu property of the
Window or WindowedApplication instance on which the menu should appear. To create an application
menu, assign the FlexNativeMenu as the menu property of the application's
WindowedApplication. To assign a FlexNativeMenu as the context menu for a portion of the user interface,
call the FlexNativeMenu instance's setContextMenu() method, passing the UI object
as an argument. Call the FlexNativeMenu component's display() method to display the
menu as a pop-up menu anywhere on one of the application's windows.
To detect when menu items commands are triggered, register a listener for the itemClick
event. You can also register a listener for the menuShow event to determine when
any menu or submenu is opened.

The object that accesses and manipulates data in the data provider. The FlexNativeMenu control delegates to the data descriptor for information about its data. This data is then used to parse and move about the data source. The data descriptor defined for the FlexNativeMenu is used for all child menus and submenus.
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 setting the property:
<mx:FlexNativeMenu id="flexNativeMenu" dataDescriptor="{new MyCustomDataDescriptor()}"/>
Alternatively, you can specify the property in MXML as a nested subtag, as the following example shows:
<mx:FlexNativeMenu>
<mx:dataDescriptor>
<myCustomDataDescriptor>
</mx:dataDescriptor>
...
The default value is an internal instance of the DefaultDataDescriptor class.

The hierarchy of objects that are used to define the structure of menu items in the NativeMenu. Individual data objects define menu items, and items with child items become menus and submenus.
The FlexNativeMenu control handles the source data object as follows:
- A String containing valid XML text is converted to an XML object.
- An XMLNode is converted to an XML object.
- An XMLList is converted to an XMLListCollection.
- Any object that implements the ICollectionView interface is cast to an ICollectionView.
- An Array is converted to an ArrayCollection.
- Any other type object is wrapped in an Array with the object as its sole entry.

The function that determines the key equivalent modifiers for each menu item.
If you omit this property, Flex uses its own default function to determine the
Array of modifiers by looking in the data provider data for the presence of
the following (boolean) fields: altKey, commandKey,
controlKey, and shiftKey.
The keyEquivalentModifiersFunction property is good for handling
formatting, localization, and platform independence.
The key equivalent modifiers function must take a single argument, which is the item in the data provider, and must return an array of modifier key names.

labelField:String| Dil Sürümü: | ActionScript 3.0 |
| Ürün Sürümü: | Flex 3 |
| Çalışma Zamanı Sürümleri: | AIR 1.1 |
The name of the field in the data provider that determines the
text to display for each menu item. 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, if each XML elementin an E4X XML Object includes a "label"
attribute containing the text to display for each menu item, set
the labelField to "@label".
In a label, you can specify the character to be used as the mnemonic index
by preceding it with an underscore. For example, a label value of "C_ut"
sets the mnemonic index to 1. Only the first underscore present is used for this
purpose. To display a literal underscore character in the label, you can escape it
using a double underscore. For example, a label value of "C__u_t" would
result in a menu item with the label "C_ut" and a mnemonic index of 3 (the "t"
character). If the field defined in the mnemonicIndexField property
is present and set to a value greater than zero, that value takes precedence over
any underscore-specified mnemonic index value.
Setting the labelFunction property causes this property to be ignored.
Varsayılan değer şudur "label".

Set to true after immediate or deferred child creation,
depending on which one happens. For a Container object, it is set
to true at the end of
the createComponentsFromDescriptors() method,
meaning after the Container object creates its children from its child descriptors.
For example, if an Accordion container uses deferred instantiation,
the processedDescriptors property for the second pane of
the Accordion container does not become true until after
the user navigates to that pane and the pane creates its children.
But, if the Accordion had set the creationPolicy property
to "all", the processedDescriptors property
for its second pane is set to true during application startup.
For classes that are not containers, which do not have descriptors,
it is set to true after the createChildren()
method creates any internal component children.

A flag that determines if an automation object shows in the automation hierarchy. Children of containers that are not visible in the hierarchy appear as children of the next highest visible parent. Typically containers used for layout, such as boxes and Canvas, do not appear in the hierarchy.
Some controls force their children to appear
in the hierarchy when appropriate.
For example a List will always force item renderers,
including boxes, to appear in the hierarchy.
Implementers must support setting this property
to true.

invalidateProperties | () | yöntem |
public function invalidateProperties():void| Dil Sürümü: | ActionScript 3.0 |
| Ürün Sürümü: | Flex 3 |
| Çalışma Zamanı Sürümleri: | AIR 1.1 |
Marks a component so that its commitProperties()
method gets called during a later screen update.
Invalidation is a useful mechanism for eliminating duplicate work by delaying processing of changes to a component until a later screen update. For example, if you want to change the text color and size, it would be wasteful to update the color immediately after you change it and then update the size when it gets set. It is more efficient to change both properties and then render the text with its new size and color once.
Invalidation methods rarely get called. In general, setting a property on a component automatically calls the appropriate invalidation method.
