Wiecie może jak to naprawić?
Z tych screenów to wiele nie widać. Ustawiłeś w klasę kontrolera? Zapodaj kod i treść błędu.
Przepraszam że otworzyłem temat a pozniej nie pisalem, ale przypadki chodzą po ludziach i po prostu nie mialem jak. błędu nie udało mi się naprawic.

Exception running application sample.Main
Process finished with exit code 1
Nie umiem jeszcze uzywać gita (chodz zauwazyłem że przydało by mi się juz nauczyć) dla tego wrzucam kod tutaj:
Plik: Main.java:
package sample;
import javafx.application.Application;
import javafx.fxml.FXMLLoader;
import javafx.scene.Parent;
import javafx.scene.Scene;
import javafx.scene.control.Button;
import javafx.scene.layout.StackPane;
import javafx.stage.Stage;
import javafx.stage.StageStyle;
import java.awt.*;
public class Main extends Application {
@Override
public void start(Stage primaryStage) throws Exception{
Parent root = FXMLLoader.load(getClass().getResource("/sample/sample.fxml"));
primaryStage.setTitle("Hello First program");
Scene scene = new Scene(root);
primaryStage.setScene(scene);
primaryStage.show();
}
public static void main(String[] args) {
launch(args);
}
}
Plik:Controller.java:
package sample;
public class Controller {
public void kk(){
System.out.println("Test");
}
}
Plik: Sample.fxml:
<?xml version="1.0" encoding="UTF-8"?>
<?import javafx.scene.control.Button?>
<?import javafx.scene.layout.StackPane?>
<StackPane maxHeight="-Infinity" maxWidth="-Infinity" minHeight="-Infinity" minWidth="-Infinity" prefHeight="400.0" prefWidth="600.0" xmlns="http://javafx.com/javafx/10.0.1" xmlns:fx="http://javafx.com/fxml/1">
<children>
<Button mnemonicParsing="false" onAction="#kk" text="Button" />
</children>
</StackPane>
dodam jeszcze że na początku mialem problemy z java 11 i zastanawiam się czy powrót do 10 nie bedzie złym pomysłem, może to coś zmieni.
Caused by: javafx.fxml.LoadException: No controller specified.
musisz określić klasę kontrolera, najprościej można to zrobić tak:
<StackPane fx:controller="sample.Controller" maxHeight="-Infinity" ...
Jakiego IDE używaż? U mnie IntelliJ (polecam) świeci na czerwono No controller specified for top level element przy onAction="#kk", gdy brakuje fx:controller.
Wywal też import z obu klas:
import java.awt.*;
Kontrolki w JavaFX i AWT mają takie same nazwy klas, więc importuj tylko te z javafx.scene.control.
