我将JFoenix库用于我的Comboboxes。
' boxLeague.getSelectionModel()。selectedItemProperty()。addListener((observable,oldValue,newValue) - > boxTeams.setItems(listPremierLeague)); '将当从boxLeague Combobox中选择任何内容时,将所有文本放到boxTeams Combobox中,但我想要做的是当在boxLeague中选择特定项目时,然后填充另一个组合框。
public class Controller implements Initializable {
@FXML
private JFXComboBox<String> boxLeague;
@FXML
private JFXComboBox<String> boxTeams;
@FXML
private JFXComboBox<String> boxPlayers;
ObservableList<String> listLeagues = FXCollections.observableArrayList(
"Bundesliga", "La Liga", "Ligue 1", "Premier League", "Serie A", "Champions League", "Europa League");
ObservableList<String> listPremierLeague = FXCollections.observableArrayList(
"Arsenal", "Bournemouth", "Brighton", "Burnley", "Chelsea", "Crystal Palace", "Everton");
@Override
public void initialize(URL location, ResourceBundle resources) {
boxLeague.setItems(listLeagues);
boxLeague.getSelectionModel().selectedItemProperty().addListener((observable, oldValue, newValue) -> boxTeams.setItems(listPremierLeague));
}
}
答案 0 :(得分:5)
在你的听众内部,你需要找出哪个联盟被选中了boxTeams
的项目。
boxLeague.getSelectionModel().selectedItemProperty().addListener(
(observable, oldValue, newValue) -> {
if (newValue.equals("Premier League")) {
boxTeams.setItems(listPremierLeague));
} // else if ... (or use a switch-case here)
}
);
请注意,如果您不会将String
用于联赛和球队,但可以创建自己的课程,则可以进一步改进。
