Hi Simon,

Thanks for your reply.
I have tried the standard approach before.
However, with the standard approach, when user choose a different language, I have to refresh the whole page to make it take effect.
The effect I am looking for is : once a user choose a different language, all labels/button will change the language automatically without refreshing the page.
Is there any way to do it ?

Thanks
Ryan :-)

Hi Peter,

Thanks for your suggestion. However, that approach might not be appropiate for my situation since our existing customer has already got used to the effect I mentioned (i.e. implemented in Swing). However, I have figured out how to achieve the effect :
1. Create an interface e.g. ComponentIF with a method reloadLocale
2. Extend existing Zk components with additional attributes (e.g. labelKey, tooltipkey ... for Button, Tab) and implemented ComponentIF.
3. Amend all zuls to point to my version of components (e.g. ?component name="window" extends="window" class="a.b.c.Window"?>)
4. Whenever user selected a different language, call comp.getDesktop() and then iterate over all its components (i.e. desktop.getComponents()) . For each components, if it is an instance of ComponentIF, simply call reloadLocale to force it to reload the labels by using attributes defined in step 2.

Up to this moment, the effect of this approach works quite well.
However, I am still looking for a way to change the css class of the component immediately since difference language may require different appearance (i.e. Can I enforce a component to look at a different css and change its appearance immediately?)

Thanks a lot
Ryan :-)
