  1. Eclipse 3.7 Indigo IDE
  2. JavaSE 1.6

Many thanks to terrytornado from ZK who gave idea for how to customize ZK Message Box.  You can see more details in the following url

http://www.zkoss.org/forum/listComment/8802-Multiline-Messagebox-updated

Step 1:

Here is the code

Step 4:



Create MessageBoxComposer.java  and Demo.zul


image

MessageBoxComposer.java


package mydomain;
 
import org.zkoss.zk.ui.Component;
import org.zkoss.zk.ui.event.Event;
import org.zkoss.zk.ui.util.GenericForwardComposer;
 
import myutility.MultiLineMessageBox;
 
@SuppressWarnings("rawtypes")
public class MessageBoxComposer extends GenericForwardComposer {
 
    private static final long serialVersionUID = 1L;
 
    public void doAfterCompose(Component comp) throws Exception {
        super.doAfterCompose(comp);
    }
 
    public void onClick$btn_MultilineMessagebox(Event event) throws InterruptedException {
        String msg = "Hallo \n\nI'm a multi line Message.";
        String title = "E r r o r !";
 
        MultiLineMessageBox.doSetTemplate();
        MultiLineMessageBox.show(msg, title, MultiLineMessageBox.OK, "ERROR", true);
    }
 
}

Demo.zul


<zk>
    <window title="Hello World!!" border="normal" width="500px"
        apply="mydomain.MessageBoxComposer">
 
        <hbox>
            <button id="btn_MultilineMessagebox"
                label="MultilineMessagebox" width="200px" />
        </hbox>
    </window>
</zk>



Step 5 :



Run the Demo.zul file. The output as folllows

Step 6 :



Now let us change the look and feel by adding external CSS File. Create the CSS File as shown below
