Hi! this is my first post,
I read some codes that talks about to use the variables from java to zul code:
<listheader label="@{Class.variable}" />
How can I do it? I tried it but not works.
Thanks for help!
Marky,
Here is an extremely simple example:
<?init class="org.zkoss.zkplus.databind.AnnotateDataBinderInit" ?>
<zk>
<zscript>
String header1 = new String("Fruits");
String header2 = new String("Color");
public class Fruit {
private String name;
private String color;
public Fruit(String n, String c) {
setName(n);
setColor(c);
}
public String getName() {
return name;
}
public void setName(String n) {
name = n;
}
public String getColor() {
return color;
}
public void setColor(String c) {
color = c;
}
}
List Fruits = new ArrayList();
Fruits.add(new Fruit("Apple", "Red"));
Fruits.add(new Fruit("Orange", "Orange"));
Fruits.add(new Fruit("Grape", "Purple"));
</zscript>
<window style="padding: 25px;">
<listbox id="lb" model="@{Fruits}">
<listhead>
<listheader label="@{header1}" style="font-weight: bold; color: #003E7E;"/>
<listheader label="@{header2}" style="font-weight: bold; color: #003E7E;"/>
</listhead>
<listitem self="@{each=Fruit}">
<attribute name="onClick">
alert("You clicked on " + lb.getSelectedItem().getLabel());
</attribute>
<listcell label="@{Fruit.name}" />
<listcell label="@{Fruit.color}" />
</listitem>
</listbox>
</window>
</zk>
As Steva77 says, it is always easier for us to help you if you post an example of your code. Please make sure you wrap your code in [code] [/code] blocks.
Welcome to ZK!
Kind regards,

What are you exaclty trying to achieve?
It seems you are trying to bind the label to a class' variable... but where are you setting it?
Maybe post some code to review.
@ = databinding sign
$ = variable sign
Thanks for the replies. Specifically I try to use the java class, no a script or embedded code in my zul. I'm not sure if this is posible because all of samples that I have seen always use the zul file to do it. I try the fruits code and it works, but doing the same in a java class no. I don't know if that's possible but I need do something like this:
<?page title="new page title" contentType="text/html;charset=UTF-8"?>
<?init class="org.zkoss.zkplus.databind.AnnotateDataBinderInit" ?>
<zk>
<window apply="Componentes.PostJava" title="new page title" border="normal">
<label id="label" value="@{value}" visible="true"></label>
</window>
</zk>
And in my java class:
public class PostJava extends GenericForwardComposer {
private static final long serialVersionUID = 1L;
String value="new content";
}
Thanks all for help!!

Marky
Sure, it can works in plain java. ZK is a JAVA web 2.0 framework.
Look at this thread. There are codes in it who are showing how to implement the databinding mechanism in pure java. methode: initDataBinding()

uOO!! Thanks people and Stephan! I can use the thread to extract the methods to work in javaclass. I'm very grateful with you.
Kind regards,
Mark.
