Javafx tableview checkbox to hide unwanted rows? - javafx

Question

I'm trying to do some reports by hiding some rows from a tableview (I made in scenebuilder) by using a checkbox. If the object from tableview doesn't have in the column a specific String, it becomes invisible. example: By clicking the checkbox, hide all rows that dont have the exact value "Barcelona" in table_adress. I tried to do this, but I keep complicating myself. Any ideas?
the function
#FXML
void CakeRequestsFromBarcelona(ActionEvent event) throws IOException {
for(Object cake:table.getItems()) {
for (TableColumn column : table.getColumns()) {
//not sure how to write it
}
}
}
initialize
#FXML
private TableColumn<CakeRequest, Integer> table_ID;
#FXML
private TableColumn<CakeRequest, String> table_adress;
#FXML
private TableColumn<CakeRequest, String> table_design;
#FXML
private TableColumn<CakeRequest, String> table_flavour;
#FXML
private TableColumn<CakeRequest, String> table_model;
#FXML
private TableColumn<CakeRequest, String> table_name;
#FXML
private TableColumn<CakeRequest, String> table_phonenumber;
#FXML
private TableView<CakeRequest> table;
public void initialize(){
//cakeRequest
table_ID.setCellValueFactory(
p-> new SimpleIntegerProperty(p.getValue().getID()).asObject()
);
table_name.setCellValueFactory(
p -> new SimpleStringProperty(p.getValue().getOwnerName())
);
table_adress.setCellValueFactory(
p -> new SimpleStringProperty(p.getValue().getOwnerAddress())
);
table_phonenumber.setCellValueFactory(
p -> new SimpleStringProperty(p.getValue().getPhoneNumber())
);
table_flavour.setCellValueFactory(
p -> new SimpleStringProperty(p.getValue().getFlavour())
);
table_design.setCellValueFactory(
p -> new SimpleStringProperty(p.getValue().getDesign())
);
table_model.setCellValueFactory(
p -> new SimpleStringProperty(p.getValue().getModel())
);
}
CakeRequest
public class CakeRequest implements Identifiable<Integer>, Serializable{
private int ID;
private String OwnerName;
private String OwnerAddress;
private String PhoneNumber;
private String Model;
private String Flavour;
private String Design;

Use a FilteredList and change the predicate when the check box is checked/unchecked:
private ObservableList<CakeRequest> data = FXCollections.observableArrayList();
private FilteredList<CakeRequest> filteredData = new FilteredList<>(data, request -> true);
public void initialize(){
// existing code...
table.setItems(filteredData);
}
#FXML
void cakeRequestsFromBarcelona(ActionEvent event) {
if (checkBox.isChecked()) {
filteredData.setPredicate(request -> request.getOwnerAddress().contains("Barcelona"));
} else {
filteredData.setPredicate(request -> true);
}
}
