List Databinding [message #63261]

Hi,
i've linked a List Object to an Arraylist contained in the model in this
way:

bindingContext.bindList(SWTObservables.observeItems(_listGen re),
BeansObservable.observeList(Realm.getDefault(), model,
"listGenre"), null, null);

_listGenre is the List object

in the model i have put

public ArrayList<String> getListGenre() {
return listGenre;
}

public void setListGenre(ArrayList<String> listGenre) {
ArrayList<String> old = listGenre;
this.listGenre = listGenre;
changeSupport.firePropertyChange("listGenre", old, listGenre);
}

In this way no items are added to the arrayList when the _listGenre is
filled with elements. What's wrong?

thanks

Christian

Hi,

I would guess that you need to provide an UpdateListStrategy
BeansObserable#observeList() call.
Attached is a snippet that shows a List widget that is bound to a model
that provides the available Locales. UpdateListStrategy, including
converters, are used there as well.
However I would rathe recommend to use a ListViewer along with an
ObservableListContentProvider.

Cheers,
R
