When i tried to compile code it have bug. I am trying to resolve problem one hour and i don't know this bug. Do you know how to fix it? Thanks!
import javafx.application.Application;
import javafx.fxml.FXMLLoader;
import javafx.scene.Scene;
import javafx.scene.control.Button;
import javafx.scene.layout.StackPane;
import javafx.stage.Stage;
public abstract class Mainn extends Application
{
public static void main(String[] args){launch(args);
public void start(Stage primaryStage) throws Exception {
FXMLLoader loader = new FXMLLoader();
loader.setLocation(this.getClass.getResource("/fxml/StackPaneWindow.fxml"));
StackPane stackPane = loader.load();
Scene scene = new Scene (stackPane);
primaryStage.setScene(scene);
primaryStage.setTitle("bang");
primaryStage.show();
}
}
}
The first problem I see with this is that the method start(Stage) is inside your main function, which isn't allowed java. Close your main function before defining another function.

I'm trying to write the simplest code to start learning how JavaFX works. Here is my code:
package app;
import javafx.application.Application;
import javafx.scene.Scene;
import javafx.scene.control.Button;
import javafx.scene.layout.BorderPane;
import javafx.scene.layout.StackPane;
import javafx.stage.Stage;
public class mainClass extends Application{
Stage primaryStage;
public static void main(String[] args) {
launch(args);
}
#Override
public void start(Stage stage) throws Exception {
primaryStage = stage;
StackPane layout = new StackPane();
Scene scene = new Scene(layout, 300, 300);
primaryStage.setScene(scene);
primaryStage.show();
}
}
It should just show an empty window. My compilator gives no errors, but nothing shows up, even if I can see my program running in my dock. How is this possible? I'm sure I'm missing some stupid simple thing, but I cannot figure out what it is.
Say You have a class with the JavaFX start().
This class is launched by another class, with main. I want to get information from the class with main, to the class with JavaFX. For some reason, a constructor won't work.
Here's the code that does the webview:
import javafx.application.Application;
import javafx.event.ActionEvent;
import javafx.event.EventHandler;
import javafx.scene.Group;
import javafx.scene.Scene;
import javafx.scene.control.Hyperlink;
import javafx.scene.layout.VBox;
import javafx.scene.web.WebEngine;
import javafx.scene.web.WebView;
import javafx.stage.Stage;
public class htmlRender extends Application {
#Override
public void start(Stage stage) {
stage.setTitle("HTML");
stage.setWidth(500);
stage.setHeight(500);
Scene scene = new Scene(new Group());
VBox root = new VBox();
final WebView browser = new WebView();
final WebEngine webEngine = browser.getEngine();
Hyperlink hpl = new Hyperlink("LINK");
hpl.setOnAction(new EventHandler<ActionEvent>() {
#Override
public void handle(ActionEvent e) {
webEngine.load("LINK");
}
});
root.getChildren().addAll(hpl, browser);
scene.setRoot(root);
stage.setScene(scene);
stage.show();
}
}
Where it says "LINK", I want to insert a string from another class.
The other class has
public static void main(String[]args){
htmlRender.launch(htmlRender.class, args);
}
JavaFX application launch parameters can be accessed via the Application.getParameters() method.
So I created a FXML interface using JavaFX's Scene Builder tool, and I'm trying to load it via my code. However, I ran into this error when trying to load my FXML document: FXMLLoader.load can't be resolved to a type.
Here is my code:
import javafx.application.Application;
import javafx.event.ActionEvent;
import javafx.event.EventHandler;
import javafx.fxml.FXMLLoader;
import javafx.geometry.Pos;
import javafx.scene.Scene;
import javafx.scene.control.Button;
import javafx.scene.control.TextField;
import javafx.scene.layout.GridPane;
import javafx.scene.layout.StackPane;
import javafx.stage.Stage;
public class Driver extends Application {
public static void main(String[] args) {
launch(args);
}
#Override
public void start(Stage primaryStage) {
Parent root = new FXMLLoader.load(getClass().getResource("interface.fxml"));
Scene scene = new Scene(root, 600, 400);
primaryStage.setTitle("Wiki Scraper");
primaryStage.setScene(scene);
primaryStage.show();
}
}
My FXML document is contained in the most top level project folder.
What am I doing incorrectly?
Try to split it up this way:
FXMLLoader loader = new FXMLLoader(this.getClass().getResource("DefaultFrame.fxml"));
Parent root = (Parent) loader.load();
dfController = loader.getController();
You can send a desktop notification with JavaFx like this (requires jdk 8u20 or later):
package sample;
import javafx.application.Application;
import javafx.scene.Scene;
import javafx.scene.control.Button;
import javafx.stage.Stage;
import org.controlsfx.control.Notifications;
public class Main extends Application {
#Override
public void start(Stage primaryStage) throws Exception{
// Parent root = FXMLLoader.load(getClass().getResource("sample.fxml"));
Button notifyButton = new Button("Notify");
notifyButton.setOnAction(e -> {
Notifications.create().title("Test").text("Test Notification!").showInformation();
});
primaryStage.setTitle("Hello World");
primaryStage.setScene(new Scene(notifyButton, 100, 50));
primaryStage.show();
}
public static void main(String[] args) {
launch(args);
}
}
But this way you have to create a main window (stage), is it possible to avoid this? I am looking for a way to send notification like using zenity in bash: most of the code is non-gui, but uses some gui elements for informing or interacting with user in a very basic fashion.
It looks like the ControlsFX notifications require a existing stage. You can create a hidden utility stage. Try something like this.
package sample;
import javafx.application.Application;
import javafx.application.Platform;
import javafx.embed.swing.JFXPanel;
import javafx.scene.Scene;
import javafx.scene.layout.StackPane;
import javafx.scene.paint.Color;
import javafx.stage.Stage;
import javafx.stage.StageStyle;
import org.controlsfx.control.Notifications;
public class Main extends Application {
#Override
public void start(Stage primaryStage) throws Exception{
}
public static void main(String[] args) {
new JFXPanel();
notifier("Good!", "It's working now!");
}
private static void notifier(String pTitle, String pMessage) {
Platform.runLater(() -> {
Stage owner = new Stage(StageStyle.TRANSPARENT);
StackPane root = new StackPane();
root.setStyle("-fx-background-color: TRANSPARENT");
Scene scene = new Scene(root, 1, 1);
scene.setFill(Color.TRANSPARENT);
owner.setScene(scene);
owner.setWidth(1);
owner.setHeight(1);
owner.toBack();
owner.show();
Notifications.create().title(pTitle).text(pMessage).showInformation();
}
);
}
}
new JFXPanel() initializes the JavaFX thread without having to extend Application. You have to call this before any calls to Platform.runLater() otherwise you will get a thread exception. You only need to call it once for the whole application though. Honestly it is probably better to create your own notification stage and display it directly. Create a stage like above and put your own contents. You can probably reuse some of the styling from the ControlsFX source.
Im Getting These Errors when trying to parse this FXML file into my Java Program.The code for when i load in the FXML file and where i get the errors are bellow
package mediarealm;
import java.io.IOException;
import java.util.logging.Level;
import java.util.logging.Logger;
import javafx.application.Application;
import javafx.fxml.FXMLLoader;
import javafx.scene.Parent;
import javafx.scene.Scene;
import javafx.stage.Stage;
import javafx.stage.StageStyle;
public class MediaRealm extends Application {
#Override
public void start(Stage primaryStage) {
Parent root = null;
primaryStage.initStyle(StageStyle.UNDECORATED);
try {
root = FXMLLoader.load(getClass().getResource("/rsrc /UIManagmentDefaultState.fxml"));
} catch (IOException ex) {
Logger.getLogger(MediaRealm.class.getName()).log(Level.SEVERE, null, ex);
}
root.setStyle("-fx-background-color: #000000;");
Scene scene = new Scene(root, 1280, 720);
primaryStage.setTitle("Hello World!");
primaryStage.setScene(scene);
primaryStage.show();
}
public static void main(String[] args) {
launch(args);
}
}
It could possibly because of the code Bellow but I don't think it is i'm trying to load in some of the elements from the fxml file into the rest of my code so that i can have full access to said elements with java.
package mediarealm;
import javafx.collections.FXCollections;
import javafx.fxml.FXML;
import javafx.scene.control.Button;
public class Controller
{
#FXML private Button ExitButton;
#FXML private static Button myVideos;
public static void doshit()
{
myVideos.setText("Addison is gay!");
}
Probably a long shot, but the line
< fx:id="myMusic" /Button>
is no correct XML, it rather should be
</Button>
