Hello,

I have a listbox where the rows are drag and drop. Order is important in my application so is there a way I can get the children of this listbox while guaranteed that their order is the same as it was in the dialog?

Thanks!

Hi diego898,

Could you elaborate your question further? Have you run into a consequence that the list retreived by getChildren() has a different order than what you see on the browser?

Regards,
Simon

I have not, but I dont suspect it is guaranteed unless it is implemented with an arrayList or linkedList or some other implementation with guaranteed ordering

Thanks

Hi diego898,

I think all type of Lists are order preserving in Java. If you are interested to see how ZK implements Listbox#getChildren(), you can trace the source code. You will see it returns a class that extends AbstractSequentialList.
