动作处理程序不适用于视图本身 [英] Action Handlers Not Working on View itself

问题描述

动作处理程序不直接作用于视图实例吗?

Do action handlers not work directly on view instances?

我不想在视图中附加一个动作处理程序，而是想将它直接附加到整个视图本身上.

Instead of attaching an action handler within the view, I want to attach it directly on the entire view itself.

更新:

我的目标是委托给 parentView 上的特定功能(在这种情况下是撤消，重做).我有 buttonView 的原因是因为点击每个按钮，我想对它做一些事情，例如向它添加一个 css 类.

My goal is to delegate to specific functions (undo, redo in this case) on the parentView. The reason I have the buttonView is because on click on each button, I want to do something to it, for example add a css class to it.

因此，实际上，我希望我的所有按钮在单击时为其自身添加一个类，然后委托给父视图上的单独功能.

So in effect, I want all my buttons to add a class to themselves on click and then delegate to separate functions on the parent view.

使用这种方法可以吗?
