TextArea will not display any information whatsoever. My goal is to display user input from TextField into TextArea. Here is my controller file:
package application.controller;
import javafx.event.ActionEvent;
import javafx.event.EventHandler;
import javafx.fxml.FXML;
import javafx.scene.control.Button;
import javafx.scene.control.TextArea;
import javafx.scene.control.TextField;
public class MainController implements EventHandler<ActionEvent>{
#FXML
TextField starshipname;
TextArea shipInfo = new TextArea();
Button shipEnter;
#Override
public void handle( ActionEvent event) {
shipInfo.appendText(starshipname.getText());
}
I have looked at other posts similar to my issue, but none of them resolve what's going on. I have tried several things like, shipInfo.setText("test"), removing the new TextArea(); gives me a NullPointerException error. Ultimately, I want to call another function from the controller to display specific information on TextArea based on the users input. First, I want to make sure I can display on the TextArea at all. Here is my main file:
package application;
import javafx.application.Application;
import javafx.fxml.FXMLLoader;
import javafx.stage.Stage;
import javafx.scene.Parent;
import javafx.scene.Scene;
public class Main extends Application {
public static Stage stage;
#Override
public void start(Stage primaryStage) {
try {
Parent root = FXMLLoader.load(getClass().getResource("../Main.fxml"));
primaryStage.setScene(new Scene(root, 800, 800));
primaryStage.show();
stage = primaryStage;
} catch(Exception e) {
e.printStackTrace();
}
}
public static void main(String[] args) {
launch(args);
}
}
Here is also my Main.fxml file:

I'm working on a desktop application using javaFX, I'm using scene builder version 11 to create my interface that contains TextFields and ChoiceBox, my inputs are supposed to be set in Arabic. The problem is when I retrieve the text from the TextFiled or the ChoiceBox and print it in the console it shows characters like that "بننلنلن" and it also generates a problem to store the inputs in database, this is the SQLException:
java.sql.SQLSyntaxErrorException: You have an error in your SQL syntax; check the manual that corresponds to your MariaDB server version for the right syntax to use near 'بننلنلن,نبلنبنلب,2021-06-30,أمر جزائي,تم التبليغ
When I tried another project without scene builder I got the Arabic outputs correctly, could scene bulider be the problem's origin?

I just want the window be in a center immediately when my program starts.
This is a bug in JavaFX itself. A workaround for until it is fixed is to do this:
primaryStage.show();
primaryStage.centerOnScreen();
You need to call centerOnScreen() immediately after show() to prevent it from showing up in the corner.
I have utilized Netbeans IDE 8.1 and JavaFX Scene Builder from Gluon to create a basic user interface with text fields.
User Action Pathway
User types in Password.
User types in the three directories in the three text fields (1. PDB..., 2. 4D..., 3. 2D...).
User clicks Enter and JavaFX checks if the password is "passwd_1234" and if it is, JavaFX outputs the three directories on three separate lines in a text file (to be used by other non-Java code as inputs).
I tried learning about Java I/O (FileReader and FileWriter) but it's implementation is quite different from that of JavaFX and FXML.

Please assist me in the Java code (I can auto-generate the controller using Source > Make Controller in Netbeans) to implement the User Action Pathway. Thanks.
You can use PrintWriter . To check if the password is the same is quite easy just getText() and use equals.
You create the File and you write to it:
PrintWriter writer = new PrintWriter(new FileWriter(file));
Then you read each field and do
writer.println(directoryName);
Don't forget to use writer.flush(); cause it not auto by default.
-->Oracle tutorial explains it better.

If you are using scene builder, go to the code section and in the On Drag Dropped textfield put the name of the method in your controller that you want to handle drag events when something is dropped on this node
Then in your controller create the body of this function to be called when the drop happens
#FXML private void somethingDropped(Event event) {
System.out.println("something dropped!");
//TODO More useful code
}
