How to clear ListBox? (ZK)

I have very simple question. I amazed, that couldn't find answer. How can I make total clearing of ListBox (org.zkoss.zul.ListBox) in ZK Framework?

Solution

  • Code below clears the Listbox, but maybe causes problems, if a model is used :

    lb.getItems().clear();

    Code below clears the selection :

    lb.clearSelection();

    Code below sets a new model, deletes the old one and all items. The Listbox will be empty if the model is empty

    lb.setModel(model);

    If you like to get a new set of Items, the last one should be the best.
    If you have a List of them use :

    lb.setModel(new ListModelList<>(myList));
