CheckGroup selectedPensCheckGroup = new CheckGroup("selectedPens",
selectedPensModel);
add(selectedPensCheckGroup);
ListView pensList = new ListView("pens", pensModel)
{
protected void populateItem(ListItem item)
{
item.add(new Check("check", item.getModel()));
// assuming pen has a nice toString()
item.add(new Label("pen", item.getModel()));
};
};
selectedPensCheckGroup.add(pensList);
Now you have one check component for each available pen and all selected pens
will be contained in selectedPensModel.
For the models there are many possibilities: AbstractReadOnlyModel,
PropertyModel, ...
