Hi, I have customized standard zk tree component by extending Tree class and defining the Model and the renderer class. So i m generating three level Tree.

  • product
    • Module
      • Jars

What i want is ,even row should have different background than odd ones. i don't want to change the style from the zul file. style should be applied on creation of tree only. Thanks in advance.

Hey @chillworld thanks for your answer, your solution is logically correct , but it isn't working .can you please check the issue. (else than .colorEven{ background:Blue}; should be .colorEven{ background:Blue;} ) if needed should i provide you the code.?

does it work when you change the ; from place? I didn't tested it out cause it was pretty simpel, of course then there could be typmistakes coming up :) (IngoB solution you can try also, with that you don't need to set the style tag)

No it doesn't works with the change also, so i m expecting the reason of not working. and the IngoB sol. works fine :)

In your renderer you have this :

public void render(Treeitem treeitem, Object data, int index) throws Exception {
}

put this in your renderer, so just see if index is even or not like this :

if (index%2==0) {
    treeitem.setStyle("background:red");
} else {
    treeitem.setStyle("background:blue");
}

Greetz chill.
