I placed a ChoiceBox inside an fxml with JavaFX Scene Builder.
The FXML has a controller assigned to it.
My question is: Which event do I need to register if I want to know about changed values?
onInputMethodTextChanged="#languageSelectionModified"
this does not work with the following code
public void languageSelectionModified(Event event) {
ChoiceBox<String> box = (ChoiceBox<String>) event.getSource();
System.out.println(box.getValue());
}
and this only works for the initial click (i.e. opening the list, not when selecting an item):
onMouseClicked="#languageSelectionModified"
Although the Mouse-Events would never be a good choise because of situations where the touch or keyboard is the input-method, it still proves that the System.out can be reached.
I have absolutly no idea where those things are documentated (in the default Java-API they are not)
The ChoiceBox is used for presenting the user with a relatively small set of predefined choices from which they may choose. The ChoiceBox, when "showing", will display to the user these choices and allow them to pick exactly one choice. When not showing, the current choice is displayed.
Add a listener to your @FXML injected choicebox in your controller:
choicebox.getSelectionModel().selectedItemProperty().addListener(choiceboxSelectionChangeListener);
You can also bind to the selected item:
label.textProperty().bind(choicebox.getSelectionModel().selectedItemProperty());
Here is an example of hooking up a listener in a controller for a ComboBox defined in FXML. Logic for a ChoiceBox is pretty much identical.
