Zscript to MVC Extractor



Introduction

For better architecture and future maintainence, it's better to follow MVC pattern to implement a web application. The extractor helps you to refactor a ZUL with Zscript to MVC way by the rules mentioned in the smalltalk: ZK MVC Made Easy.


Step by Step

In the first, we have a ZUL file with event listener inside Zscript.

<window id="win" >
	<button id="btn" onClick='alert("aaa");' />
	<button id="att">
		<attribute name="onClick">
		<![CDATA[
			alert("bbb");
		]]>
		</attribute>
	</button>
</window>

You can select a component, and then click the extractor icon in toolbar.

Or right click to show the context menu, and then click "ZK MVC Extractor"

A dialog will be shown to ask you some detail configurations, just like new a java class. The default class name is based on the id of the selected component.

The modified ZUL file and generated java file would be like:

<window id="win" >
	<button id="btn"/>
	<button id="att">		
	</button>
</window>

and

import org.zkoss.zk.ui.Component;
import org.zkoss.zk.ui.util.GenericForwardComposer;
import org.zkoss.zul.Button;
import org.zkoss.zul.Window;

public class WinViewCtrl extends GenericForwardComposer {

	private Window win;
	private Button att;
	private Button btn;

	@Override
	public void doAfterCompose(Component comp) throws Exception {
		super.doAfterCompose(comp);
		// TODO Auto-generated method stub

	}

	public void onClick$att() {
		//TODO: please check if you have use "self" or zscript functions here.

		alert("bbb");

	}

	public void onClick$btn() {
		//TODO: please check if you have use "self" or zscript functions here.
		alert("aaa");
	}

}
