ZK MVC Using GenericForwardComposer utility class

Welcome back

This is the 4th post in a series of ZK MVC

Here is the zk documentation and we are following that
and creating new example

http://books.zkoss.org/wiki/Small_Talks/2008/August/ZK_MVC_Made_Easy




Here is the Summary

Method 1 : Implements Composer
We implement Composer interface. Here we used getfellow method to hold the
reference for the UI Components and also we added listener to handle
events

Here is the Link for the first post
http://emrpms.blogspot.in/2012/04/mvc-using-composer-interface.html


Method 2 : extends GenericComposer
Here, we removed all the event lisener by extending the GenericComposer
But remember, we need to call super doaftercompose.

Here is the link for the second post
http://emrpms.blogspot.in/2012/04/zk-mvc-using-genericcomposer-utility.html

Method 3: extends GenericAutowireComposer
Here, we removed all the getfellow methods and let them auto wired
Here we dont need override doaftercompose

http://emrpms.blogspot.in/2012/04/zk-mvc-using-genericautowirecomposer.html

Until now, the previous example codes always use the forward attribute in zul file to forward
event of the button click. Can we remove such forward attributes?"

The org.zkoss.zk.ui.util.GenericForwardComposer utility class is designed to fulfill this requirement. Note that GenericForwardComposer extends the GenericAutowireComposer class, so it has all features of its parent class(GenericAutowireComposer) and grandparent class(GenericComposer).

Here is my zul code

<window

border="normal" width="700px" apply="com.me.Example9">

<columns>
<column label="" />
<column label="" />
</columns>
<rows>
<row>
First Name :
<textbox id="firstName" />
</row>
<row>
Last Name :
<textbox id="lastName" />
</row>
<row>
Address :
<textbox id="address" />
</row>
<row>
<button id="Clear" label="Clear" />
</row>

</rows>
</grid>
</window>
</zk>


In the above code, we have used apply attribute of the XML. By this, we are associating
with a component, such that the composer can control the UI rooted the given component.

Here is composer(java file)


package com.me;

import org.zkoss.zk.ui.event.Event;
import org.zkoss.zk.ui.util.GenericForwardComposer;
import org.zkoss.zul.Textbox;

@SuppressWarnings("rawtypes")
public class Example9 extends GenericForwardComposer {

private static final long serialVersionUID = 1L;
private Textbox firstName;
private Textbox lastName;
private Textbox address;

public void onClick$Clear(Event event) {
firstName.setValue("");
lastName.setValue("");
address.setValue("");
}
}

Important Notes in the above code.

1. The event handler must be declared as public. Otherwise, they will be ignored from auto-wiring.



Here is the demo

ZK MVC Using .GenericAutowireComposer utility class

This is the third post in a series of ZK MVC

I am just following the zk documentation and creating another sample 

here is the ZK Documentation url

http://books.zkoss.org/wiki/Small_Talks/2008/August/ZK_MVC_Made_Easy 

Before this, summary of the previous post is

We started with Composer 

http://emrpms.blogspot.in/2012/04/mvc-using-composer-interface.html

Then we removed all the event listeners and it is done by zk automatically by  genericcomposer utility class

http://emrpms.blogspot.in/2012/04/zk-mvc-using-genericcomposer-utility.html

Now we will see how we can remove all those binding using getfellow methods. This can be done

using org.zkoss.zk.ui.util.GenericAutowireComposer utility class which extends GenericComposer class and add the auto-wire features

Here is my zul code

<?page title="Example7" contentType="text/html;charset=UTF-8"?>

<textbox id="address" />

</row>

<row>

<button id="Clear" label="Clear" forward="onClick=onClear_btn"/>

</row>

</rows>

</grid>

</window>

</zk>

Here is my Composer java file

package com.me;


import org.zkoss.zk.ui.event.Event;
import org.zkoss.zk.ui.util.GenericAutowireComposer;
import org.zkoss.zul.Textbox;


@SuppressWarnings("rawtypes")
public class Example8 extends GenericAutowireComposer {


private static final long serialVersionUID = 1L;
private Textbox firstName; //auto-wired
private Textbox lastName; //auto-wired
private Textbox address; //auto-wired


//all getFellow() codes are removed

public void onClear_btn(Event event) {
firstName.setValue("");
lastName.setValue("");
address.setValue("");
}
}

Again here is the source code and demo

http://zkfiddle.org/direct/3hjk8af/5/v6.0.0-MVC-Using-GenericAutowireComposer?run=3gbaqbu

In the next post, we will see how to Get Rid of Those "forward" Attributes

using GenericForwardComposer

ZK MVC Using .GenericComposer utility class

This is the second post in a series of ZK MVC

This post is continuation of previous post

ZK Documentation is here
http://books.zkoss.org/wiki/Small_Talks/2008/August/ZK_MVC_Made_Easy

Now we will use Genericcomposer class to reduce some code from my previous post



Here is my zul file

</row>
<row>
<button id="Clear" label="Clear" forward="onClick=onClear_btn"/>
</row>

</rows>
</grid>
</window>
</zk>


Here is my Composer



package com.me;

import org.zkoss.zk.ui.Component;
import org.zkoss.zk.ui.event.Event;
import org.zkoss.zk.ui.util.GenericComposer;
import org.zkoss.zul.Textbox;

@SuppressWarnings("rawtypes")
public class Example7 extends GenericComposer {

/**
*
*/
private static final long serialVersionUID = 1L;
private Textbox firstName;
private Textbox lastName;
private Textbox address;

public void doAfterCompose(Component comp) throws Exception {
/**
* Dont forget to call super doaftercomposer. By calling this, it will add the event listner for us
*/
super.doAfterCompose(comp);
// locate ZK components
firstName = (Textbox) comp.getFellow("firstName");
lastName = (Textbox) comp.getFellow("lastName");
address = (Textbox) comp.getFellow("address");

// all addEventListener and new EventListener() codes are removed
}

public void onClear_btn(Event event) {
firstName.setValue("");
lastName.setValue("");
address.setValue("");
}
}

ZK MVC Using composer interface

This is the first post in a series of ZK MVC

Just going thru the following link to get some idea about MVC
http://books.zkoss.org/wiki/Small_Talks/2008/August/ZK_MVC_Made_Easy

Everything went fine as long as i copied and paste from the examples
But when i started my own example, got into problem and came to know some concepts or tricks or whatever be


Here is my first example on MVC using composer interface. Later on i will post how we can do this with other ways

This example simply clearly all the values in the form.

Here is my Zul File

<?page title="Example1" contentType="text/html;charset=UTF-8"?>

</row>
<row>
<button id="Clear" label="Clear" forward="onClick=onClear_btn"/>
</row>

</rows>
</grid>
</window>
</zk>


Here is my composer


package com.me;

import org.zkoss.zk.ui.Component;
import org.zkoss.zk.ui.event.Event;
import org.zkoss.zk.ui.event.EventListener;
import org.zkoss.zk.ui.util.Composer;
import org.zkoss.zul.Textbox;
import org.zkoss.zul.Window;

public class Example6 implements Composer {

private Textbox firstName;
private Textbox lastName;
private Textbox address;

public void doAfterCompose(Component comp) throws Exception {


firstName = (Textbox) comp.getFellow("firstName");
lastName = (Textbox) comp.getFellow("lastName");
address = (Textbox) comp.getFellow("address");

// define and register event listeners
comp.addEventListener("onClear_btn", new EventListener() {
public void onEvent(Event event) throws Exception {
firstName.setValue("");
lastName.setValue("");
address.setValue("");
}
});
}

}

Here is the demo with source code download
Demo

Here the composer1.zul defines the View of the application while the MyComposer1 class intervenes in the life cycle of the window creation and is responsible for the definition and registration of the event listener. However, the more you write these codes, the more you will find the same addEventListener pattern occurs repeatedly. So..., "Can we take away those addEventListener codes?"

The org.zkoss.zk.ui.util.GenericComposer utility class is ZK's response to this question.

Patient Demographics

Patient browse (search) is the key element for any EMR / PMS Software. In my past 15 years experience, i involved more than 5 times in design/development (using VB6, VB.NET) / test the Patient demographics search and patient demographics page.

Here is the excellent UI which shows how to design patient search window
