方法详情

add

public function add(ContentPanel... panel)
Add the passed ContentPanel(s)
参数：
  • panel : ContentPanel...
    The ContentPanel(s) to add (you can pass more than one)
返回：
  • Ext.ContentPanel
    The panel added (if only one was added)
This method is defined by BasicLayoutRegion.

addEvents

public function addEvents(Object object)
将对象中没有的事件从给出的对象中复制过来。给出的对象必须也继承于 Observable 对象此方法才会有效果。
参数：
  • object : Object
    要复制事件的源对象
返回：
  • void
This method is defined by Observable.

addListener

public function addListener(String eventName, Function handler, [Object scope], [Object options])
为组件添加一个事件监听器
参数：
  • eventName : String
    侦听事件的类型
  • handler : Function
    事件调用的方法
  • scope : Object
    （可选）处理函数执行的作用域。处理函数 "this" 的内容。
  • options : Object
    （可选）一个包含处理设置属性的对象。可以包含下列的属性：
    • scope {Object} 处理函数执行的作用域。处理函数 "this" 的内容。
    • delegate {String} 一个简单的选择器用来过滤目标或查找目标的子节点。
    • stopEvent {Boolean} 值为 True 时用来中止事件。那样将中止传播，并防止缺省动作。
    • preventDefault {Boolean} 值为 True 时用来防止缺省动作。
    • stopPropagation {Boolean} 值为 True 时用来中止事件传播。
    • normalized {Boolean} 值为 False 时向处理函数传递浏览器事件用以代替 Ext.EventObject 对象。
    • delay {Number} 当事件触发后启用处理函数的延迟微秒数。
    • single {Boolean} 值为 True 时将添加一个处理函数用来处理下个触发的事件，并在处理完后移除。
    • buffer {Number} 使处理函数计划在由 Ext.util.DelayedTask 指定的微秒数后执行。如果事件在延迟期间再次触发，原来的处理函数将不再启动，而是由新的计划代替。

    组合选项
    使用选项参数可以组合不同类型的监听器：

    下面是一个标准的、延迟执行的、一次性的监听器，将会自动停止事件并传递一个自定义的参数(forumId)

    代码： 
    el.on('click', this.onClick, this, { single: true, delay: 100, stopEvent : true, forumId: 4 });

    这个方法也允许传递的单个参数是一个包含多个指定处理函数的设置对象。

    一次调用多个处理函数
    代码：

    el.on({ 'click' : { fn: this.onClick scope: this, delay: 100 }, 'mouseover' : { fn: this.onMouseOver scope: this }, 'mouseout' : { fn: this.onMouseOut scope: this } });

    或者简写为：
