@DefaultProperty("items") public class ChoiceBox<T> extends Control
By default, the ChoiceBox has no item selected unless otherwise specified. 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. 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
.
Example:
ChoiceBox cb = new ChoiceBox(); cb.getItems().addAll("item1", "item2", "item3");

Property Details

selectionModel
The selection model for the ChoiceBox. Only a single choice can be made, hence, the ChoiceBox supports only a SingleSelectionModel. Generally, the main interaction with the selection model is to explicitly set which item in the items list should be selected, or to listen to changes in the selection to know which item has been chosen. -
showing
Indicates whether the drop down is displaying the list of choices to the user. This is a readonly property which should be manipulated by means of the #show and #hide methods.- See Also:
isShowing()
-
items
The items to display in the choice box. The selected item (as indicated in the selection model) must always be one of these items.- See Also:
getItems()
,setItems(ObservableList)
-
converter
Allows a way to specify how to represent objects in the items list. When a StringConverter is set, the object toString method is not called and instead its toString(object T) is called, passing the objects in the items list. This is useful when using domain objects in a ChoiceBox as this property allows for customization of the representation. Also, any of the pre-built Converters available in thejavafx.util.converter
package can be set.- Since:
- JavaFX 2.1
- See Also:
getConverter()
,setConverter(StringConverter)
-
value
