I'm new to javaFX and I wanted to make a simple code that counted how many times a person pressed a button and displayed the count on the application itself. Currently I have my code printing the counter in my IDE and would just like to some how attach it to the scene(eg I click run and every time I click the button it prints how many times I've clicked it in my workbench). I looked around stack overflow and youtube but the closest I got to what I was looking for was printing it in my IDE. Thanks for any help.
import javafx.application.Application;
import javafx.scene.Scene;
import javafx.scene.control.Button;
import javafx.scene.layout.HBox;
import javafx.scene.layout.Pane;
import javafx.scene.paint.Color;
import javafx.stage.Stage;
public class JavaFXTest extends Application {
private int counter = 0;
public static void main (String [] args){
Application.launch();
}
#Override
public void start(Stage primaryStage) throws Exception {
Stage stage = new Stage();
stage = primaryStage;
Pane pane = new Pane();
pane.setPrefSize(400,400);
Button button = new Button("Smash it!");
HBox root = new HBox(5, pane);
button.setOnAction(e -> {
counter();
});
root.getChildren().add(button);
Scene scene1 = new Scene(root,1000, 800, Color.AQUA);
stage.setScene(scene1);
stage.setTitle("ButtonSmash!");
stage.show();
}
public void counter(){
counter++;
System.out.println(counter);
}
}
Here is the full code:
package StackOverFlow;
import javafx.application.Application;
import javafx.scene.Scene;
import javafx.scene.control.Button;
import javafx.scene.control.Label;
import javafx.scene.layout.HBox;
import javafx.scene.layout.Pane;
import javafx.scene.paint.Color;
import javafx.stage.Stage;
public class JavaFXTest extends Application {
private int counter = 0;
private Label label = new Label("Count: ");
public static void main (String [] args){
Application.launch();
}
#Override
public void start(Stage primaryStage) throws Exception {
Stage stage = new Stage();
stage = primaryStage;
Pane pane = new Pane();
pane.setPrefSize(400,400);
Button button = new Button("Smash it!");
HBox root = new HBox(5, pane);
button.setOnAction(e -> {
label.setText("Count: "+Integer.toString(counter));
counter();
});
root.getChildren().add(button);
label.relocate(0, 0); // You can put this label, wherever you want!
root.getChildren().add(label);
Scene scene1 = new Scene(root,1000, 800, Color.AQUA);
stage.setScene(scene1);
stage.setTitle("ButtonSmash!");
stage.show();
}
public void counter(){
counter++;
//System.out.println(counter);
}
}
You had to make one label and to add it to your pane.getChildren();
And whenever you press the button you need to change text from that label.

The buttons dont give a console output. Two buttons are in a Vbox at the bottom of a BorderPane and should print "new" or "continue" when pressed.
I followed a tutorial and tried to extend it to one more button.
import javafx.application.Application;
import javafx.event.ActionEvent;
import javafx.event.EventHandler;
import javafx.geometry.Insets;
import javafx.scene.Scene;
import javafx.scene.control.Button;
import javafx.scene.layout.BorderPane;
import javafx.scene.layout.VBox;
import javafx.stage.Stage;
public class Main extends Application implements EventHandler<ActionEvent> {
Button btn1, btn2;
public static void main(String[] args) {
launch(args);
}
public void start(Stage primaryStage) throws Exception {
primaryStage.setTitle("title");
Button btn1 = new Button("new");
Button btn2 = new Button ("continue");
btn1.setOnAction(this);
btn2.setOnAction(this);
VBox vb = new VBox (btn1, btn2);
vb.setSpacing(10);
vb.setPadding(new Insets(20));
BorderPane root = new BorderPane();
root.setBottom(vb);
Scene scene = new Scene (root, 300, 250);
primaryStage.setScene(scene);
primaryStage.show();
}
#Override
public void handle(ActionEvent event) {
if (event.getSource()==btn1) {
System.out.println("new!");
} else if (event.getSource()==btn2) {
System.out.println("continue!");
}
}
}
nothing happens, but there should be a output of "new or continue"
Remove class from buttons.
This way the code will use buttons from fields, instead of creating new ones.
public void start(Stage primaryStage) throws Exception {
primaryStage.setTitle("title");
btn1 = new Button("new");
btn2 = new Button ("continue");
// the rest of the code will be the same
}
I have created a simple app to simulate dynamic node creation with JAVAFX.
This app has the ability to create a new window whenever user want it by clicking the "New" button.
User can add a new node which is TitledPane to the window by clicking "Add Task" button and then clicking "Add" button on the dialog window.
There are an unexpected behavior which I want to fix. This app is only add new node (TitledPane in this case) to the last created window.
And the all of the nodes on the previous window will vanish.
You can see the following video to better understand what I mean.

Why that weird behavior happening and how to fix it so it only adds new node to the same window where the clicked "Add Task" button is located?
These fields should not be static:
public static VBox listWrapper;
public static ScrollPane listScroller;
I recently started coding in FXML/JavaFX using Eclipse and one of the projects I'm working on requires me to make a drop down menu with combobox, checkboxes etc.. So my question is would it be possible to make the MenuButton display a VBox/HBox when clicked with those inside?
Here is a one of the simplest example of menu:
import javafx.application.Application;
import javafx.scene.Group;
import javafx.scene.Scene;
import javafx.scene.control.Menu;
import javafx.scene.control.MenuBar;
import javafx.scene.control.MenuItem;
import javafx.stage.Stage;
public class MenuFX extends Application {
#Override
public void start(Stage primaryStage) throws Exception {
Group group = new Group();
Scene scene = new Scene(group, 800, 600);
MenuBar menuBar = new MenuBar();
Menu someValues = new Menu("Values");
for (int i = 0; i < 60; i++) {
MenuItem item = new MenuItem("Value " + i);
someValues.getItems().add(item);
}
menuBar.getMenus().add(someValues);
group.getChildren().addAll(menuBar);
primaryStage.setScene(scene);
primaryStage.show();
}
public static void main(String[] args) {
launch(args);
}
}
More expanding example here.
When I change scenes on my stage with the following code, my stage changes size. However the button in the top right to maximize/minimize the windows says that the stage is still maximized even though it is clearly not.
How am I able to keep the stage maximized when a scene change happens?
import javafx.application.Application;
import javafx.concurrent.Task;
import javafx.geometry.Pos;
import javafx.scene.Scene;
import javafx.scene.control.Label;
import javafx.scene.control.ScrollPane;
import javafx.scene.image.Image;
import javafx.scene.image.ImageView;
import javafx.scene.layout.StackPane;
import javafx.scene.layout.VBox;
import javafx.scene.text.Font;
import javafx.stage.Stage;
public class Program2 extends Application {
public static void main(String[] args) {
launch(args);
}
#Override
public void start(Stage primaryStage) {
try {
StackPane p = new StackPane();
primaryStage.setTitle("Chart Application");
Label loader = new Label("Loading...");
loader.setGraphic(new ImageView(new Image("https://media.giphy.com/media/FmcNeI0PnsAKs/giphy.gif")));
loader.setFont(new Font(35));
p.setStyle("-fx-background: #FFFFFF;");
p.getChildren().add(loader);
StackPane.setAlignment(loader, Pos.CENTER);
primaryStage.setScene(new Scene(p));
primaryStage.setMaximized(true);
Task<VBox> task = new Task<VBox>() {
#Override
public VBox call() {
VBox result = new VBox();
for(int i = 0; i < 50000; i++) { //Here simply for small delay
result.getChildren().add(new Label(Integer.toString(i)));
}
return result ;
}
};
task.setOnSucceeded(e -> {
VBox result = task.getValue();
ScrollPane scrollPane = new ScrollPane();
scrollPane.setContent(result);
scrollPane.setStyle("-fx-background: #FFFFFF;");
primaryStage.setScene(new Scene(scrollPane));
});
new Thread(task).start();
primaryStage.show();
} catch (Exception e) {
e.printStackTrace();
}
}
}
As this is operating system specific I image I am using Windows 10 with JDK 8 u112 and JavaFX 8 with the e(fx)clipse plugin for eclipse
Instead of replacing the scene, use the same scene and replace its root:
primaryStage.getScene().setRoot(scrollPane);
I have a TextField in my program that will have data entered by the user, but I also have a variable value somewhere else that I need to permanently display at the end of my TextField. It cannot disappear when the user enters any data in the TextField. Can anyone give me a good implementation? Thanks.
[UserInput (miles)]
**Above is an example of what I am talking about. "Miles" needs to always be in the TextField while the UserInput is changing.
EDIT: "Implementation" was a bad choice of words. Let me rephrase, I can set up the field myself, but I am having trouble finding a way to set permanent text in a textfield. Just wondering if anyone knows an easy way.
You could put a transparent textfield over a label and bind the 2 together. Something like this but with better styling.
import javafx.application.Application;
import javafx.beans.binding.Bindings;
import javafx.scene.Scene;
import javafx.scene.control.Label;
import javafx.scene.control.TextField;
import javafx.scene.layout.StackPane;
import javafx.scene.layout.VBox;
import javafx.stage.Stage;
public class Text extends Application {
#Override
public void start(Stage primaryStage) {
TextField txtUser = new TextField();
txtUser.setStyle("-fx-background-color: transparent;-fx-border-color:blue;");
Label txtBG = new Label(" (miles)");
Label labelUser = new Label();
labelUser.textProperty().bind(txtUser.textProperty());
Label labelAll = new Label();
labelAll.textProperty().bind(Bindings.concat(
labelUser.textProperty())
.concat(txtBG.textProperty()));
StackPane sp = new StackPane();
sp.getChildren().addAll(txtBG, txtUser);
sp.setPrefSize(100, 12);
VBox root = new VBox();
root.getChildren().addAll(sp,labelUser,labelAll);
Scene scene = new Scene(root, 300, 250);
primaryStage.setTitle("transparent text test");
primaryStage.setScene(scene);
primaryStage.show();
}
}
I would use a HBox instead of a stack pane but it's one way to satisfy the requirement that "miles" is 'inside' the texfield's borders.
This is a small example doing what you want ! I have used the focus property of textfield to add and remove miles from it !

user.setStyle("-fx-background-color: transparent;-fx-border-color:blue;");
user.focusedProperty().addListener(new ChangeListener<Boolean>()
{
#Override
public void changed(ObservableValue<? extends Boolean> arg0, Boolean oldPropertyValue, Boolean newPropertyValue)
{
if (newPropertyValue)
{
user.setText(user.getText().replace(" miles", ""));
}
else
{
user.setText(user.getText().concat(" miles"));
}
}
});
VBox root = new VBox();
root.getChildren().addAll(user,demo);
Scene scene = new Scene(root, 300, 250);
