ZK 8.0
This page is under construction, so we cannot guarantee the accuracy of the content!
Introduction
ZK 8 added several new Features mainly improving Component control when using the MVVM design pattern. The question I sometimes heard since was: (How )can we benefit from these features in our MVC application ?
To answer the question I'll start with the most prominent features which are:
- shadow elements
- form proxies
Let's have a look where they can be used in the MVC world.
If you are missing a feature let us know in the comments section below.
