问题
I am trying to populate tables in separate tabs in TabPane.
I was able to populate only the one in first tab like this:
@FXML
public void initialize(URL url, ResourceBundle rb) {
//assert serviceChoiceBox1 != null : "fx:id=\"serviceChoiceBox1\" was not injected: check your FXML file 'ScheduleServicePane.fxml'.";
ServiceName.setCellValueFactory(new PropertyValueFactory<Service, String>("name"));
ServicePrice.setCellValueFactory(new PropertyValueFactory<Service, Double>("price"));
ServiceDuration.setCellValueFactory(new PropertyValueFactory<Service, Integer>("duration"));
TableView.setItems(List());
}
private ObservableList<Service> List(){
ObservableList<Service> service = FXCollections.observableArrayList(serviceRepository.list());
return service;
}
I have two more tabs with tables but somehow I am not able to fill them with prepared list of data that I have
I want to populate other tabs with similar data
Anyone can help?
I also read about separate Controllers for each tab but this seems to be to much in such a case.
回答1:
I would use FilteredList in this case. This will allow you to create "sublist" of the original list. In this demo, I create a "type" field in the Service class. I then filter the original list based on the "type". You don't have to create a "type" field, but you will need to find something to filter on if you don't.
