sorry for my previous post.. what i've previously done is:
- add a filtertoolbar to your datatable
- make some of your columns IFilteredColumn, for example I've used
TextFilteredPropertyColumn but there are also others
- make your dataprovider implement IFilterStateLocator
- implement the filtering logic by checking the current state of the
filter in your iterator method
- no need to change html
I'm not sure if that's the best way to do it, but it may help you get
started..
Thx for your help!
I'am currently trying to figure how to use TextFilteredPropertyColumn
and what model he needs.
my dataProvider is a list of, say, Incident with firstName, lastName,
and age
My non filtered columns are :
final IColumn[] columns = new IColumn[3];
int col = 0;
columns[col++] = new PropertyColumn(new Model(firstName),
firstName, firstName);
columns[col++] = new PropertyColumn(new Model(lastName), lastName,
lastName);
columns[col++] = new PropertyColumn(new Model(age), age, age);
Now I want to filter of lastname so I replace the PropertyColumn by a :
columns[col++] = new TextFilteredPropertyColumn(new
ResourceModel(lastName), lastName lastName);
?? but I got an error ...
..
Ok I think I have understood :
the getFilterModel method of TextFilteredPropertyColumn return a
PropertyModel bases on the form model. The form model is
FilterStateModel based on the IFilterStateLocator. So the
TextFilteredPropertyColumn set a property of the object used as the
getFilterState of the IFilterStateLocator.
So I just need to create a POJO and use it as the structure to store the
filter state. I can use a People (I filter on the same column) but I
prefer to use another class (I have some multicolumns filter..)
So :
1/ create a POJO FilterState with a string property name
filterdFirstName (I use voluntary another attr name id order to be
clear)
2/ set the initial filter State on the provider :
provider.setFilterState(new IncidentFilter());
3/ transform column in instances of IFilteredColumn, like
TextFilteredPropertyColumn but be careful, the property is target and
instanca of the FilterState ! that is what I was missing!
new TextFilteredPropertyColumn(new Model(object.filterdFirstName),
author, author);
object is the property name of the filtestate in the FilterStateModel
(which is an instance of IncidentFilter
filterdFirstName is the property of I want to set in the
IncidentFilter
4/ implements IFilterStateLocator in the DataProvider
public Object getFilterState() {
return filter;
}
public void setFilterState(final Object state) {
filter = (IncidentFilter) state;
}
5/and use the filter in the iterator of the DataProvider
for (final Incident incident : list) {
if ((filter.getAuthor() != null)
!
incident.getAuthor().toLowerCase().contains(filter.getAuthor().toLowerCase())) {
continue;
}
filteredList.add(incident);
}
-(this is some bad code (prefer filter in the DAO, use internal var to
limit .toLowerCase calls...) : just to learn wicket filter? after I
delete all and restart)
6/ And voilà it works!
Awesome!! Just have to get the trick.

add(form);
but I dont know what html comes with that and how to implements the

I have google that the phonebook application is using filter but I
can't get it.
I have to say that I dont know how to start with only the javadoc (how
to write html? simple example?)
I you have a piece of code of how to use filter and
IFilterStateLocator...

Re: filtering a datatable
I reply to myself... I just have found http://www.nabble.com/Problems-with-clearing-of-filter-form-td16098239.html I have to include the table in a form with some form specific components (focus-restore and focus-tracker) form wicket:id=filter-form input type=hidden name=tracker wicket:id=focus-tracker/ table wicket:id=datatable/table span wicket:id=focus-restore[call to focus restore script]/span /form and here is the java : final DefaultDataTable table = new DefaultDataTable(datatable, columns, provider, 30); final FilterForm form = new FilterForm(filter-form, provider); table.addTopToolbar(new FilterToolbar(table, form, provider)); form.add(table); add(form); Next I have read in FilterToolbar that the filter are found by using columns with instances of IFilteredColumn like FilteredAbstractColumn... So I just replace the column declaration : before : new PropertyColumn(new Model(author), author, author) after (with filter) new TextFilteredPropertyColumn(new Model(author), author, author); and hop, the column header change in a texfield! great! when I enter some text I got an error (Attempted to set property value on a null object. Property expression: author Value: go) .. but it's seems better...
