/**
|
|
* Action menu popup widget for echo items.
|
|
*
|
|
* We don't currently have anything that properly answers the complete
|
|
* design for our popup menus in OOUI, so this widget serves two purposes:
|
|
* 1. The MenuSelectWidget is intended to deliver a menu that relates
|
|
* directly to its anchor, so its sizing is dictated by whatever anchors
|
|
* it. This is not what we require, so we have to override the 'click' event
|
|
* to reset the width of the menu.
|
|
* 2. It abstracts the behavior of the item menus for easier management
|
|
* in the item widget itself (which is fairly large)
|
|
*
|
|
* @class
|
|
* @extends OO.ui.ButtonWidget
|
|
*
|
|
* @constructor
|
|
* @param {Object} [config] Configuration object
|
|
* @cfg {jQuery} [$overlay] A jQuery element functioning as an overlay
|
|
* for popups.
|
|
* @cfg {number} [menuWidth=300] The width of the popup menu
