public class QuerySelect
Provides a Cayenne Query Select control: <select></select>.
Query Select |
DataContext
obtained via DataContext.getThreadDataContext(), and are executed
as required by the onProcess() and toString() methods.
QuerySelect has no dependency on CayenneForm
and can be used
separately in other forms or controls.
DataRow
objects containing "VALUE" and "LABEL" values, which are rendered as the
option values and labels.
QuerySelect title = new QuerySelect("title"); title.setQueryValueLabel("system.titles", "VALUE", "LABEL"); form.add(title);The example below uses a
SelectQuery
defined in code and renders
the Delivery object type and description properties
and the option values and labels.
QuerySelect delivery = new QuerySelect("delivery", true); delivery.setSelectQuery(new SelectQuery(Delivery.class)); delivery.setOptionValue("type"); delivery.setOptionLabel("description"); form.add(delivery);The last example uses a
Decorator
to render the select options label.
QuerySelect userSelect = new QuerySelect("user", true); userSelect.setSelectQuery(new SelectQuery(User.class)); userSelect.setOptionValue("username"); userSelect.setDecorator(new Decorator() { public String render(Object object, Context context) { User user = (User) object; return user.getFirstName() + " " + user.getLastName(); } }); form.add(userSelect);
