Habe eine Lösung gefunden und wollte die einfach mal mitteilen:
[code=Java]import javafx.application.Application;
import javafx.scene.Group;
import javafx.scene.Scene;
import javafx.scene.control.TextArea;
import javafx.stage.Stage;
public class MainApp extends Application {
public TextArea textOut = new TextArea();
@Override
public void start(Stage stage) {
Group root = new Group();
Scene scene = new Scene(root, 800, 800);
textOut.setPrefSize(300, 100);
textOut.setLayoutX(50);
textOut.setLayoutY(500);
root.getChildren().add(textOut);
stage.setTitle("World of Zuul"); // Fenstertitel
stage.setScene(scene);
Test test = new Test(this);
test.welcome();
stage.show();
}
public void print(String text){
textOut.setText(text);
}
public static void main(String[] args) {
launch(args);
}
}
[/code]
[code=Java]public class Test {
private MainApp ma;
public Test(MainApp ma){
this.ma=ma;
}
public void welcome() {
System.out.println("Hallo Console");
ma.print("Hallo GUI");
}
}
[/code]
