Examples of org.zkoss.zul.ListModelExt.sort()

org.zkoss.zul.ListModelExt.sort()

It called when {@link Listbox} or {@link Grid} has to sortthe content.

After sorting, this model shall notify the instances of {@link org.zkoss.zul.event.ListDataListener} (registered thru {@link ListModel#addListDataListener}) to update the content. Typically you have to notify with

new ListDataEvent(this, ListDataEvent.CONTENTS_CHANGED, -1, -1)

to denote all data are changed (and reloading is required).

The comparator assigned to, say, {@link Listheader#setSortAscending}is passed to method as the cmpr argument. Thus, developers could use it as a tag to know which column or what kind of order to sort. @param cmpr the comparator assigned to {@link Listheader#setSortAscending}and other relative methods. If developers didn't assign any one, the default comparator is used. @param ascending whether to sort in the ascending order (or inthe descending order)

            return;
        }


        ListModelExt model = (ListModelExt) getModel();
        if (lastSortedColumnAscending) {
            model.sort(lastSortedColumn.getSortAscending(),
                    lastSortedColumnAscending);
        } else {
            model.sort(lastSortedColumn.getSortDescending(),
                    lastSortedColumnAscending);
        }

        ListModelExt model = (ListModelExt) getModel();
        if (lastSortedColumnAscending) {
            model.sort(lastSortedColumn.getSortAscending(),
                    lastSortedColumnAscending);
        } else {
            model.sort(lastSortedColumn.getSortDescending(),
                    lastSortedColumnAscending);
        }
    }
