Ext 禁用grid

你disable后 grid上面会有一层遮罩，你应该都是无法点击到行数据的呀？怎么可能还出发事件呢？你能截个图么？让我看看你disabled后而又出发双击事件是怎么样的

如果你要把双击事件un掉的话，你可以这样

grid.un('celldblclick',function(){

//你disabled我就移除

});

不知道这个是不是你指的双击.

直接un掉不就不响应双击事件了

un( String eventName, Function handler, [Object scope] ) : void
Removes a listener (shorthand for removeListener)
Removes a listener (shorthand for removeListener)
Parameters:

eventName : String
The type of event to listen for
handler : Function
The handler to remove
scope : Object
(optional) The scope (this object) for the handler
Returns:

void

多看看api文档
