Property Detail

contextMenuOwner

property
contextMenuOwner:InteractiveObject

Language Version: ActionScript 3.0
Runtime Versions: AIR 1.0 Flash Player 9

The display list object to which the menu is attached. This could be the mouse target (mouseTarget) or one of its ancestors in the display list.



Implementation
    public function get contextMenuOwner():InteractiveObject
    public function set contextMenuOwner(value:InteractiveObject):void

isMouseTargetInaccessible

property 
isMouseTargetInaccessible:Boolean

Language Version: ActionScript 3.0
Runtime Versions: AIR 1.0 Flash Player 10

Indicates whether the mouseTarget property was set to null for security reasons. If the nominal value of menuTarget would be a reference to a DisplayObject in another security sandbox, then menuTarget is set to null unless there is permission in both directions across this sandbox boundary. Permission is established by calling Security.allowDomain() from a SWF file, or providing a policy file from the server of an image file, and setting the LoaderContext.checkPolicyFile flag when loading the image.



Implementation
    public function get isMouseTargetInaccessible():Boolean
    public function set isMouseTargetInaccessible(value:Boolean):void

See also

mouseTarget

property 
mouseTarget:InteractiveObject

Language Version: ActionScript 3.0
Runtime Versions: AIR 1.0 Flash Player 9

The display list object on which the user right-clicked to display the context menu. This could be the display list object to which the menu is attached (contextMenuOwner) or one of its display list descendants.

The value of this property can be null in two circumstances: if there no mouse target, for example when you mouse over something from the background; or there is a mouse target, but it is in a security sandbox to which you don't have access. Use the isMouseTargetInaccessible() property to determine which of these reasons applies.



Implementation
    public function get mouseTarget():InteractiveObject
    public function set mouseTarget(value:InteractiveObject):void

Constructor Detail

ContextMenuEvent

()Constructor
public function ContextMenuEvent(type:String, bubbles:Boolean = false, cancelable:Boolean = false, mouseTarget:InteractiveObject = null, contextMenuOwner:InteractiveObject = null)

Language Version: ActionScript 3.0
Runtime Versions: AIR 1.0 Flash Player 9

Creates an Event object that contains specific information about menu events. Event objects are passed as parameters to event listeners.

Parameters
type:String — The type of the event. Possible values are:
  • ContextMenuEvent.MENU_ITEM_SELECT
  • ContextMenuEvent.MENU_SELECT
 
bubbles:Boolean (default = false) — Determines whether the Event object participates in the bubbling stage of the event flow. Event listeners can access this information through the inherited bubbles property.
 
cancelable:Boolean (default = false) — Determines whether the Event object can be canceled. Event listeners can access this information through the inherited cancelable property.
 
mouseTarget:InteractiveObject (default = null) — The display list object on which the user right-clicked to display the context menu. This could be the contextMenuOwner or one of its display list descendants.
 
contextMenuOwner:InteractiveObject (default = null) — The display list object to which the menu is attached. This could be the mouseTarget or one of its ancestors in the display list.

toString

()method 
override public function toString():String

Language Version: ActionScript 3.0

MENU_ITEM_SELECT

Constant
public static const MENU_ITEM_SELECT:String = "menuItemSelect"

Language Version: ActionScript 3.0
Runtime Versions: AIR 1.0 Flash Player 9

Defines the value of the type property of a menuItemSelect event object.

This event has the following properties:

PropertyValue
bubblesfalse
cancelablefalse; there is no default behavior to cancel.
contextMenuOwnerThe display list object to which the menu is attached.
currentTargetThe object that is actively processing the Event object with an event listener.
mouseTargetThe display list object on which the user right-clicked to display the context menu.
targetThe ContextMenuItem object that has been selected. The target is not always the object in the display list that registered the event listener. Use the currentTarget property to access the object in the display list that is currently processing the event.

ContextMenuEventExample.as

The following example uses the ContextMenuEventExample class to remove the default context menu items from the Stage and add a new menu item that changes the color of a square on the Stage. The example carries out the following tasks:
  1. The myContextMenu property is declared and then assigned to a new ContextMenu object and the redRectangle property (of type Sprite) is declared.
  2. The removeDefaultItems() method is called. This method removes all built-in context menu items except Print.
  3. The addCustomMenuItems() method is called. This method places a Reverse Colors menu item in the defaultItems array by using the push() method of Array. A menuItemSelect event listener is added to the ContextMenuItem object and the associated method is called menuItemSelectHandler(). This method prints some trace() statements whenever the user selects Reverse Colors from the context menu. In addition the red square becomes black and the black text becomes red.
  4. Back in the constructor, a menuSelect event listener is added, along with the associated method menuSelectHandler(), which simply prints out three trace() statements every time an item in the context menu is selected.
  5. The constructor calls addChildren(), which draws a red square and adds it to the display list, which immediately displays the square.
  6. Finally, myContextMenu is assigned to the context menu of the redRectangle property, so that the custom context menu is displayed only when the mouse pointer is over the square.
