Examples of org.zkoss.zul.TreeModel

org.zkoss.zul.TreeModel
This interface defines the methods that component like {@link Tree}use to get the content of items.
Note: changing a render will not cause the tree to re-render. If you want it to re-render, you could assign the same model again (i.e., setModel(getModel())), or fire an {@link TreeDataEvent} event. @author Jeff Liu @since ZK 3.0.0

    for (Treeitem treeitem : getTreeitems(getTreechildren(), false)) {
      if (treeitem.isOpen()) {
        openedValues.add(treeitem.getValue());
      }
    }
    TreeModel model = getModel();
    setModel(null);
    setModel(model);
    Treeitem selectedItem = null;
    for (Treeitem treeitem : getTreeitems(getTreechildren(), true)) {
      if (treeitem.getValue() == selectedValue) {
