I am trying to build 3 different tables the will be be independent from each other. For some reason the cells are showing but are blank. Any idea what I am doing wrong?
Main:
package application;
import java.util.logging.Level;
import java.util.logging.Logger;
import javafx.application.Application;
import javafx.fxml.FXMLLoader;
import javafx.stage.Stage;
import javafx.scene.Scene;
import javafx.scene.layout.BorderPane;
public class Main extends Application {
#Override
public void start(Stage primaryStage) {
try {
BorderPane root = (BorderPane)FXMLLoader.load(getClass().getResource("GUISCENEBUILDER.fxml"));
Scene scene = new Scene(root,850,700);
scene.getStylesheets().add(getClass().getResource("application.css").toExternalForm());
primaryStage.setScene(scene);
primaryStage.setTitle("Switch Utility");
primaryStage.show();
} catch(Exception e) {
Logger.getLogger(Main.class.getName()).log(Level.SEVERE,null,e);
e.printStackTrace();
}
}
public static void main(String[] args) {
Application.launch(Main.class, (java.lang.String[]) null);
}
}
Product class: (Bad naming convention) (Going to change it to Press1)
package application;
import javafx.beans.property.SimpleStringProperty;
public class Product {
private final SimpleStringProperty windowTime;
public Product(String windowTimes) {
this.windowTime = new SimpleStringProperty(windowTimes);
}
public String getwindowTime() {
return windowTime.get();
}
public void setwindowTime(String newTime) {
windowTime.set(newTime);
}
Press2 class:
package application;
import javafx.beans.property.SimpleStringProperty;
public class Press2 {
private final SimpleStringProperty windowTime2;
public Press2(String windowTimes2) {
this.windowTime2 = new SimpleStringProperty(windowTimes2);
}
public String getwindowTime2() {
return windowTime2.get();
}
public void setwindowTime2(String newTime) {
windowTime2.set(newTime);
}
}
Press3:
package application;
import javafx.beans.property.SimpleStringProperty;
public class Press3 {
private final SimpleStringProperty windowTime3;
public Press3(String windowTimes3) {
this.windowTime3 = new SimpleStringProperty(windowTimes3);
}
public String getwindowTime2() {

ScrollPane scrolls down by itself

I have a screen where the root component is a ScrollPane. However, when the dialog is opened, the scrollbar is already scrolled all the way down. I checked what getVvalue() returned during initialize() and it was 0. I tried using setVvalue() to both 0 and 1 in initialize(), but none worked.
Main.java:
public class Main extends Application {
#Override
public void start(Stage primaryStage) throws Exception {
Scene scene = new Scene(new ScrollableDialog(), 1024, 768);
primaryStage.setScene(scene);
primaryStage.show();
}
public static void main(String[] args) {
launch(args);
}
}
ScrollableDialog.java:
public class ScrollableDialog extends ScrollPane {
public ScrollableDialog() {
FXMLLoader loader = new FXMLLoader(getClass().getResource("/pkg/lib/fxml/scrollable-dialog.fxml"));
loader.setRoot(this);
loader.setController(this);
try {
loader.load();
} catch (IOException exception) {
exception.printStackTrace();
}
}
#FXML
public void initialize() {
System.out.println(getVvalue());
}
}

As you can see, there's another custom component being used, FormEntry. Here it goes:
FormEntry.java
public class FormEntry extends VBox {
#FXML Label keyLabel;
#FXML Label valueLabel;
private String keyText;
private String valueText;
public FormEntry(#NamedArg("keyText") String keyText, #NamedArg("valueText") String valueText) {
this.keyText = keyText;
this.valueText = valueText;
FXMLLoader loader = new FXMLLoader(getClass().getResource("/pkg/lib/fxml/form-entry.fxml"));
loader.setRoot(this);
loader.setController(this);
try {
loader.load();
} catch (IOException exception) {
exception.printStackTrace();
}
}
#FXML
public void initialize() {
keyLabel.setText(keyText);
valueLabel.setText(valueText);
}
public String getKeyText() {
return keyText;
}
public void setKeyText(String keyText) {
this.keyText = keyText;
keyLabel.setText(keyText);
}
public String getValueText() {
return valueText;
}
public void setValueText(String valueText) {
if (valueText == null || valueText.isBlank() || valueText.isEmpty()) {
this.valueText = "-";
} else {
this.valueText = valueText;
}
valueLabel.setText(this.valueText);
}
public void setValueText(int number) {
this.valueText = String.valueOf(number);
}
}

Do you have an idea of what may be causing this?

In the secureCAController, initialize the agent and launch the application, but when i try to execute one method for example myAgent.getname() return null.
Anyone can help me? I dont know a lot of about javafx sorry if it is a dummy error.
myAgent is an object, that contains a lot of methods.

Maybe this will help you a little..
if you want to pass myAgent to the Controller Class from the Application Class. Your Application class has to look like the following. And you have to make a setter for the myAgent variable in the Controller Class.

To initialize or to not initialize JavaFX TextField [duplicate]

This question already has answers here:
What's the difference between fx:id and id: in JavaFX?
(4 answers)
Closed 4 years ago.
I have a JavaFX app that has the function to bring up a FileChooser. I just want to get the path of the file selected and set a Text Field to that path in the app. I need to re-use this function 4 times. Every time, I pass the TextField ID to the function it says it's null and then get the NullPointerException. I've tried several different solutions that said to create an initialize() for it, but that does not work either.
Multiple sources said to initialize the text field objects such as:
TextField global_dataset_1 = new TextField();
Then some sources said don't do that and to just refer to the .fxml IDs; which is what I thought originally to do... I tried the first one above by declaring it in the beginning and wrapping it into an #Override initialize(). Neither worked. I have the IDs set in the .fxml file.
I've also looked at: http://tutorials.jenkov.com/javafx/filechooser.html and https://examples.javacodegeeks.com/desktop-java/javafx/fxml/javafx-fxml-controller-example/ and https://github.com/mwilchek/Restaurant-Gift-Card-Lookup-App/blob/master/src/controller/NewAccountController.java

Any help would be greatly appreciated!

You have errors with how you've built your FXML file. Within your tags, you need to set the node's ID using fx:id but you only do id.
Your TextFields should be changed to:
<TextField fx:id="global_dataset_1" ...
A couple side notes:
You may want to use field.setText() instead of appendText() unless your intention is to allow them to select multiple files and list them all in the same text field.
Also, in your controller class, you should declare your nodes as private:
#FXML
private TextField global_dataset_1;
Lastly, sharing your primaryStage as a public field is not necessary (or recommended). Another way to open the FileChooser centered would be to get the current Window from any node declared in your controller:
File selectedFile = fileChooser.showOpenDialog(
global_dataset_1.getScene().getWindow());

Here is your error (in your fxml file):
<Button fx:id="result" mnemonicParsing="false" onAction="#processOperators" prefWidth="50.0" text="/">
<font>
<Font size="18.0" />
</font>
</Button>
This button id is "result" which is also the id of a label. You should either remove this id attribute (I think you missplaced it there) or change it to the one suggested by the tutorial.
UPDATE
This operation is division but you are adding the numbers number1 and number2
case "/":
if(number2==0) return 0;
return number1+number2;
so you should perform a division not addition
case "/":
if(number2==0) return 0;
return number1/number2;
UPDATE 2
Another error I spotted is also here:
float output = model.calculate(number2, number2, operator);
You missed the number1 variable in the calculate method:
float output = model.calculate(number1, number2, operator);

JavaFX DatePicker returning null

So I looked through questions and found this one, which was similar to my problem, but didn't address my issues as I haven't initialized my date pickers in my java file.
I created a date picker. Its fx:id in the fxml file matches its name in the corresponding controller. For some reason, whether I manually type a value or select a date from the calendar, datePicker.getValue() ALWAYS returns null. Can anyone think of why this might be happening?
My code is exactly as the situation I've described here. I have a DatePicker called lowEndDate. I have not initialized it. Upon the click of a button, I want to get its value, but it returns null. Does anyone have any idea why this might be? Perhaps I've missed a step. Thank you.

Code:
public void searchOKButtonClicked(ActionEvent e){
boolean searchComplete = false;
User currentUser = LoginController.currentUser;

Alert alert = new Alert(AlertType.ERROR);
alert.setContentText("Oops! At least one field is required to search.");
alert.show();
}
}
The trouble here: lowEndDate and highEndDate are ALWAYS null, regardless of input.

Sara, I've tested your fxml file using this simple project
Main
import javafx.application.Application;
import javafx.fxml.FXMLLoader;
import javafx.scene.Parent;
import javafx.scene.Scene;
import javafx.stage.Stage;
public class Main extends Application {
#Override
public void start(Stage primaryStage) throws Exception{
Parent root = FXMLLoader.load(getClass().getResource("sample2.fxml"));
primaryStage.setTitle("Hello World");
primaryStage.setScene(new Scene(root));
primaryStage.show();
}
public static void main(String[] args) {
launch(args);
}
}
Controller
import java.net.URL;
import java.util.ResourceBundle;
import javafx.event.ActionEvent;
import javafx.fxml.FXML;
import javafx.fxml.Initializable;
import javafx.scene.control.Alert;
import javafx.scene.control.Alert.AlertType;
import javafx.scene.control.DatePicker;
public class Controller implements Initializable {
#FXML
DatePicker lowEndDate;
public void searchOKButtonClicked(ActionEvent e){
Alert alert = new Alert(AlertType.ERROR);
alert.setContentText("Oops! At least one field is required to search. " + " " + lowEndDate.getValue());
alert.show();
}
#Override
public void initialize(URL arg0, ResourceBundle arg1) {
// TODO Auto-generated method stub
}
}
In your fxml, I've changed the naming in the two datepickers, I think that lowEndDate must be above highEndDate
<DatePicker fx:id="lowEndDate" layoutX="20.0" layoutY="92.0" promptText="dd/mm/yyyy" />
<DatePicker fx:id="highEndDate" layoutX="20.0" layoutY="148.0" promptText="dd/mm/yyyy" />
This is the result that I've obtained when I introduce a date
Maybe you have an error in another part of your controller but the datepickers seem to work fine.
