ControlPane

package source;

import javafx.event.ActionEvent;
import javafx.event.EventHandler;
import javafx.fxml.FXML;
import javafx.fxml.FXMLLoader;
import javafx.scene.Node;
import javafx.scene.Parent;
import javafx.scene.Scene;
import javafx.scene.control.Button;
import javafx.scene.control.PasswordField;
import javafx.scene.control.TextField;
import javafx.stage.Stage;
import java.io.IOException;
import java.util.Scanner;

public class ControlPanel {
    @FXML
    Button button;
    @FXML
    PasswordField passField;
    @FXML
    TextField loginPanel;
    @FXML
    Button btnOpenNewWindow;
    public void show(){
        System.out.println("Work");
    }
    @FXML
    public void log (){
        Scanner scanner = new Scanner(System.in);
        String login =loginPanel.getText();
        String login1 = "ala";
        String pass = passField.getText();
//        String pass1 = "1234";
        if(login.equals(login1)&& pass.equals("123")){
            System.out.println("zalogowales sie");
        }else{
            System.out.println("Nie zalogowales sie ");
        }
    }

        public void handle(ActionEvent event) {
            try {
                FXMLLoader fxmlLoader = new FXMLLoader(getClass().getResource("source/menuPane.fxml"));
                Parent root1 = (Parent) fxmlLoader.load();
                Stage stage = new Stage();
                stage.setTitle("My New Stage Title");
                stage.setScene(new Scene(root1, 450, 450));
                stage.show();
            }
            catch (IOException e) {
                e.printStackTrace();
            }
        }
    }

First fxml:

<?xml version="1.0" encoding="UTF-8"?>
<?import javafx.scene.control.Button?>
<?import javafx.scene.control.TextField?>
<?import javafx.scene.layout.StackPane?>
<?import javafx.scene.layout.FlowPane?>
<?import javafx.scene.control.PasswordField?>
<FlowPane prefHeight="334.0" prefWidth="445.0" xmlns:fx="http://javafx.com/fxml/1"  fx:controller="source.ControlPanel" >
    <children >

        <TextField fx:id="loginPanel" alignment="BOTTOM_LEFT" text="source.Login" />
        <PasswordField fx:id="passField" alignment="BOTTOM_LEFT"  />

        <Button fx:id="button" text="Logowanie"  onAction="#handle"/>
    </children>

</FlowPane>

Second Fxml:

    <?xml version="1.0" encoding="UTF-8"?>
    <?import javafx.scene.control.Button?>
    <?import javafx.scene.control.TextField?>
    <?import javafx.scene.layout.StackPane?>
    <?import javafx.scene.layout.FlowPane?>
    <?import javafx.scene.control.PasswordField?>
    <?import javafx.scene.control.Label?>
    <FlowPane prefHeight="334.0" prefWidth="445.0" xmlns:fx="http://javafx.com/fxml/1" fx:controller="source.ControlPanel" >
        <children >

            <Label text="Second Window"/>
        </children>

Answer 1

The error is in the line Caused by: java.lang.IllegalStateException: Location is not set. , which is related to

 FXMLLoader fxmlLoader = new FXMLLoader(getClass().getResource("source/menuPane.fxml"));
 Parent root1 = (Parent) fxmlLoader.load();

Most likely the resource source/menuPane.fxml is not in the path relative to the class. If you would do a System.out.println(getClass().getResource("source/menuPane.fxml")) my guess is that you get null . Given that your path starts with source I'm led to believe that you are under the impression that the runtime will have access to the source.

Make sure that the FXML resource is available in the runtime classpath, make sure that the path you specify is correct according to the runtime classpath.

Answer 2

When i change this :

FXMLLoader fxmlLoader = new FXMLLoader(getClass().getResource("/source/menuPane.fxml"));

on this:

FXMLLoader fxmlLoader = new FXMLLoader(getClass().getResource("/source/stackPanel.fxml"));

I get the same window so it works on stack panel .. but i dont know why when i write menuPane program doesnt work. I have good path /source/menuPane.fxml this is in the same package.

Answer 3

I get this now.
