How to access combobox' from another class?

Question

Java

When a user logs in, he selects his category in the combobox, and when I open orders, I want orders that belong to that combobox to be displayed. So, how to refer to the combobox (cbnameofservice in the FXMLzakazuserController.java class) which is in another class (UserjoinController.java )?

Answer 1

My implementation goes through SkinBuilder. So I'll let you know the way I do. On the combo box, I select On Action, the predefined method for loading the plate, depending on the data from the combo box.

Method for displaying data in TableView depending on the data in the combobox

public void orderByAreaOnline() {
        if (cbSetAreaOnline.getSelectionModel().getSelectedItem().toString().equals("-")) {
            clearAreaOnlineNoDateWithAreaCB();
            loadTableViewAreaOnline(obListAreaOnline, connToKZ, tableAreaOnline);
        } else {
            refreshJournalOnLineSelectArea(obListAreaOnline, TABLE_JOURNAL, tableAreaOnline, connToKZ, pst, rs, cbSetAreaOnline);
        }
    }

clearAreaOnlineNoDateWithAreaCB - nothing like that, just clearing text fields from unnecessary data.

private void loadTableViewAreaOnline(ObservableList oblist, Connection conn, TableView table) {
        oblist.clear();
        try {
            String sql = "SELECT journal.idauto, "
                    + "journal.dateAreaOut,  "
                    + "journal.areaTimeOut,  "
                    + "journal.number,  "
                    + "journal.mark,  "
                    + "journal.model,  "
                    + "journal.driver,  "
                    + "journal.mileageOut,  "
                    + "journal.mechMileageOut,  "
                    + "journal.fuelMainOut,  "
                    + "journal.fuelAddOut,  "
                    + "journal.fuelMechOut,  "
                    + "journal.areaOut,  "
                    + "journal.vehicleID,  "
                    + "vehicleList.fuelNorm "
                    + "FROM journal join vehicleList on journal.vehicleID = vehicleList.vehicleId "
                    + "where journal.status = '" + VEH_STATUS_ONLINE + "' "
                    + "ORDER by journal.dateAreaOut, journal.areaTimeOut";
            pst = conn.prepareStatement(sql);
            pst.setQueryTimeout(40000);
            rs = pst.executeQuery();

            while (rs.next()) {
                oblist.add(new ModelTableOnline(
                        rs.getString("idauto"),
                        rs.getString("dateAreaOut"),
                        rs.getString("areaTimeOut"),
                        rs.getString("number"),
                        rs.getString("mark"),
                        //                        
                        rs.getString("model"),
                        rs.getString("driver"),
                        rs.getString("mileageOut"),
                        rs.getString("mechMileageOut"),
                        rs.getString("fuelMainOut"),
                        rs.getString("fuelAddOut"),
                        rs.getString("fuelMechOut"),
                        rs.getString("areaOut"),
                        rs.getString("vehicleID"),
                        rs.getString("fuelNorm")
                ));
            }
            table.setItems(oblist);
        } catch (SQLException ex) {
            Logger.getLogger(TableController.class.getName()).log(Level.SEVERE, null, ex);
        }
    }
