Method Detail

sort

public void sort(java.util.Comparator cmpr,
                 boolean asc)

Description copied from interface: ListModelExt

It called when Listbox or Grid has to sort the content.

After sorting, this model shall notify the instances of ListDataListener (registered thru ListModel.addListDataListener(org.zkoss.zul.event.ListDataListener)) 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, Listheader.setSortAscending(java.util.Comparator) 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.

Specified by:

sort in interface ListModelExt

Parameters:

cmpr - the comparator assigned to Listheader.setSortAscending(java.util.Comparator) and other relative methods. If developers didn't assign any one, the default comparator is used.

asc - whether to sort in the ascending order (or in the descending order)

invalidate

public void invalidate()

getElementAt
