flash.ui.ContextMenuItem (ActionScript 3.0)

Package	flash.ui
Class	public final class ContextMenuItem
Inheritance	ContextMenuItem EventDispatcher Object

Language Version :

ActionScript 3.0

Player Version :

Flash Player 9

Use the ContextMenuItem class to create custom menu items to display in the Flash Player context menu. Each ContextMenuItem object has a caption (text) that is displayed in the context menu. To add a new item to a context menu, you add it to the customItems array of a ContextMenu object.

With the properties of the ContextMenuItem class you can enable or disable specific menu items, and you can make items visible or invisible.

You write an event handler for the menuItemSelect event to add functionality to the menu item when the user selects it.

Custom menu items appear at the top of the context menu, above any built-in items. A separator bar always divides custom menu items from built-in items.

Restrictions:

You can add no more than 15 custom items to a context menu.
Each caption must contain at least one visible character.
Control characters, newlines, and other white space characters are ignored.
No caption can be more than 100 characters long.
Captions that are identical to any built-in menu item, or to another custom item, are ignored, whether the matching item is visible or not. Menu captions are compared to built-in captions or existing custom captions without regard to case, punctuation, or white space.

The following captions are not allowed, but the words may be used in conjunction with other words to form a custom caption (for example, although "Paste" is not allowed, "Paste tastes great" is allowed):

None of the following words can appear in a custom caption on their own or in conjunction with other words:
```

```

Note: When the player is running on a non-English system, the caption strings are compared to both the English list and the localized equivalents.

Dispatched when a user selects an item from a context menu. The user generates the context menu by clicking the secondary button of the user's pointing device.

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

This event has the following properties:

Property	Value
`bubbles`	`false`
`cancelable`	`false`; there is no default behavior to cancel.
`contextMenuOwner`	The display list object to which the menu is attached.
`currentTarget`	The object that is actively processing the Event object with an event listener.
`mouseTarget`	The display list object on which the user right-clicked to display the context menu.
`target`	The 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.

Examples How to use examples

ContextMenuItemExample.as

The following example uses the class ContextMenuBuiltInItemsExample to remove the default context menu items from the Stage and add a new menu item. This is accomplished with the following steps:

A property myContextMenu is declared and then assigned to a new ContextMenu object.
The method removeDefaultItems() is called, which removes all built-in context menu items except Print.
The method addCustomMenuItems() is called, which places a menu item called Hello World into the customItems array by using the push() method of Array.
The Hello World context menu item is added to the Stage's context menu item list.
A TextField object with the text "Right Click Here" is added to the stage.

    import flash.ui.ContextMenu;
    import flash.ui.ContextMenuItem;
    import flash.ui.ContextMenuBuiltInItems;
    import flash.display.Sprite;
    import flash.text.TextField;

    public class ContextMenuItemExample extends Sprite {
        private var myContextMenu:ContextMenu;

        public function ContextMenuItemExample() {
            myContextMenu = new ContextMenu();
            removeDefaultItems();
            addCustomMenuItems();
            this.contextMenu = myContextMenu;
            addChild(createLabel());
        }

        private function removeDefaultItems():void {
            myContextMenu.hideBuiltInItems();

            var defaultItems:ContextMenuBuiltInItems = myContextMenu.builtInItems;
            defaultItems.print = true;
        }

        private function addCustomMenuItems():void {
            var item:ContextMenuItem = new ContextMenuItem("Hello World");
            myContextMenu.customItems.push(item);
        }
        
        private function createLabel():TextField {
            var txtField:TextField = new TextField();
