ZK Component Development Essentials/Handling Events/How we Implement the Event/Overriding bind and unbind

The following diagrams outline when the bind_(Desktop, Skipper, Array) and unbind_(Skipper, Array) methods are called. Firstly let’s take a look at how binding works.

The unbind_(Skipper, Array) function is very similar. Upon detaching the widget from the DOM the unbind_(Skipper, Array) method is called to enable us to perform tasks such as adding and removing listeners to avoid memory leaks. The diagram below demonstrates this.

Now that we have had a brief introduction of bind_(Desktop, Skipper, Array) and unbind_(Skipper, Array) let’s see the methods put into action when we bind appropriate listeners for events.
