Hi, I would like to find an application wide solution to get open/closed icons in all groupbox captions.

There is a proposed solution in the Demo: http://www.zkoss.org/zkdemo/layout/group_box

And another here: http://emrpms.blogspot.ch/2012/05/group-box-with-collapse-and-expand.html

But both solutions require me to copy/paste a lot of stuff all over the place. I only want to define this once.

This works (instead of setLabel I plan to use setImage later on):

  <groupbox onOpen='self.getFirstChild().setLabel(self.isOpen() ? "Open" : "Closed")' >
    <caption label="Caption" />

  </groupbox>

But when I try to define this attribute value in the language add-on, it does not work:

<language-addon>    
  <addon-name>myapp</addon-name>
  <language-name>xul/html</language-name>        
  <component>
    <component-name>groupbox</component-name>
    <extends>groupbox</extends>
    <custom-attribute>
      <attribute-name>onOpen</attribute-name>
      <attribute-value>self.getFirstChild().setLabel(self.isOpen() ? "Open" : "Closed")</attribute-value>
    </custom-attribute>
  </component>
</language-addon>

Is it not possible to define event code in the language add on?

regardless the answer, onOpen is a event, and custom-attribute is the attribute by component.setAttribute(), they are totally different.

good to know, that was just a naive assumption on my part, because in the zk demo they have zul markup like this: <attribute name="onOpen"><![CDATA[cb.setChecked(self.isOpen());]]></attribute>

Here is my example

zk.xml

<zk>
    <language-config>
        <addon-uri>/WEB-INF/lang-addon.xml</addon-uri>
    </language-config>
</zk>

lang-addon.xml

<language-addon>
    <addon-name>simple</addon-name>
    <depends>zul</depends>
    <language-name>xul/html</language-name>

    <component>
        <component-name>groupboxex</component-name>
        <component-class>simple.GroupboxEx</component-class>
        <extends>groupbox</extends>
    </component>
</language-addon>

GroupboxEx.java

package simple;

import org.zkoss.zk.ui.event.OpenEvent;
import org.zkoss.zul.Caption;
import org.zkoss.zul.Groupbox;

public class GroupboxEx extends Groupbox{

    private static final long serialVersionUID = 1L;


    public void onOpen(OpenEvent evt){
        Caption cp = getCaption();
        if(cp!=null){
            cp.setLabel(evt.isOpen()?"Open":"Close");
        }
    }

}

demo.zul

<vlayout spacing="15px">
    <hbox spacing="15px">
        <groupboxex width="300px">
            <caption label="Open"/>
            ABCD
        </groupboxex>
    </hbox>
</vlayout>

Thank you dennis . I learned new stuff today :)

yes this did solve my question, thanks a lot. I also had to set the 3d mold in the constructor. I figured out that I need to provide an explicit setter which delegates to the super class if I want to be able to specify a library property in the zk.xml.
