@DefaultProperty(value="items") public class ChoiceBox<T> extends Control
The ChoiceBox can be configured either to support null
as a
valid choice, or to prohibit it. In the case that it is prohibited, there
will always be some item that is selected, as long as there is at least
one item defined. By default, no item is selected unless
otherwise specified. In the case that null
is acceptable,
a default entry may be inserted into the list of choices at the top,
with a name similar to "None" and localized for different Locales.
Although the ChoiceBox will only allow a user to select from the predefined list, it is possible for the developer to specify the selected item to be something other than what is available in the predefined list. This is required for several important use cases.
It means configuration of the ChoiceBox is order independent. You may either specify the items and then the selected item, or you may specify the selected item and then the items. Either way will function correctly.
ChoiceBox item selection is handled by
SelectionModel
As with ListView and ComboBox, it is possible to modify the
SelectionModel
that is used,
although this is likely to be rarely changed. ChoiceBox supports only a
single selection model, hence the default used is a SingleSelectionModel
.
import javafx.scene.control.ChoiceBox; ChoiceBox cb = new ChoiceBox(); cb.getItems().addAll("item1", "item2", "item3");
