| Method Summary | |
| public void | sort(Comparator cmpr, boolean ascending)
It called when
Listbox or
Grid has to sort
the content.
After sorting, this model shall notify the instances of
org.zkoss.zul.event.ListDataListener (registered thru
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,
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.
Parameters:
cmpr - the comparator assigned to Listheader.setSortAscendingand other relative methods. |
