Set Icon on Stage in JavaFX

I wanted to know how should I set icons on javaFX stage. I have found this method, but it did not work properly.

  stage.getIcons().add(new Image(iconImagePath));

stage is an instance of javafx.stage.Stage, and I have imported javafx.scene.image.Image. This is the exception which we receive:

Invalid URL: Invalid URL or resource not found

Also, there is nothing wrong with the iconImagePath, its value is "G:/test.jpg" and there is a jpg file in the G drive named test. In addition, when we use ImageIO to read the same URL we can do it easily.

import javafx.application.Application;
import javafx.fxml.FXMLLoader;
import javafx.scene.Scene;
import javafx.stage.Stage;
import javafx.scene.image.Image;
import javafx.scene.layout.StackPane;


import java.io.IOException;

public class HelloApplication extends Application {
    @Override
public void start(Stage stage) throws IOException {
    FXMLLoader fxmlLoader = new FXMLLoader(HelloApplication.class.getResource("hello-view.fxml"));
    Scene scene = new Scene(fxmlLoader.load(), 320, 240);
    stage.getIcons().add(new Image(HelloApplication.class.getResource("icon.png").openStream()));
    stage.setTitle("Hello!");
    stage.setScene(scene);
    stage.show();
}

public static void main(String[] args) {
    launch();
}
}

The icon.png is in the same folder as file hello-view.fxml. I am on Debian 12 with KDE and with openjdk 22.0.1 and javafx 22.0.1. I tried many answers with my IDE Netbeans without success(STREAM CAN NOT BE NULL exceptions) - but IntelliJIdea Community edition IDE has suggested me use the .openStream(). So big thanks.

I use netbeans 8.2, if I use :

stage.getIcons().addAll(new Image(getClass().getResourceAsStream("home-icon32.png")));

I have to put the image in src directory. Don't know why, but works only this way. I've tried putting it in build/classes, but negative.

If you're using eclipse make sure you add the folder that has the image to the build path. this way you can refer to the image with its name with no problems.enter image description here

Here is the working code, which is exactly what you neened:

import javafx.application.Application;
import javafx.event.ActionEvent;
import javafx.event.EventHandler;
import javafx.scene.Scene;
import javafx.scene.control.Button;
import javafx.scene.layout.StackPane;
import javafx.stage.Stage;

/**
 *
 * @author Manikant gautam
 * This is a beginner's sample application
 * using JAVAFX
 * 
*/

public class Helloworld extends Application {

    @Override
    public void start(Stage primaryStage) {
        Button btn = new Button();
        btn.setText("Say 'Hello World'");
        btn.setOnAction(new EventHandler<ActionEvent>() {
            @Override
            public void handle(ActionEvent event) {
                System.out.println("Hello World!");
            }
        });

        StackPane root = new StackPane();
        root.getChildren().add(btn);

        Scene scene = new Scene(root, 300, 250);
        // Set Icon From Here.
        primaryStage.getIcons().add(
            new Image("/resource/graphics/app_logo.png"));
        primaryStage.setTitle("Hello World!");
        primaryStage.setScene(scene);
        primaryStage.show();
    }


    public static void main(String[] args) {
        launch(args);
    }
}

Set Icon by statement:

primaryStage.getIcons().add(new Image("/resource/graphics/app_logo.png"));

// Set the icon
stage.getIcons().add(new Image(getClass().getResourceAsStream("penguin.png")));

I faced the same problem. I used Netbeans. I'm not sure if the folder structure is different for other IDEs, but I had to put the picture in /build/classes/(package that contains the JavaFX class file). This means it doesn't go into the src folder.

Best Way:

stage.getIcons().add(new Image(getClass().getResource(IconImagePath).toExternalForm()));

stage.getIcons().add(new Image(getClass().getResourceAsStream("bal.png")));

This example works. I placed an icon in the same folder/package as the source .java file.

don't forget that your icon must be in 32x32 or 16x16 resolution, if not, it doesn't work.

The solution is:

File f = new File("image.png");
Image ix = new Image(f.toURI().toString());
stage.getIcons().add(ix);

This is what I've done and it work. The image is located in the root of my resource folder.

stage.getIcons().add(new Image("/ubuntu-mini.png"));

I am using JavaFX 8

The constructors of javafx.scene.image.Image expect a URI, not a (full) path. This URI can either be relative (e.g. /images/flower.png) or absolute (e.g. file:flower.png).

Strings like G:/test.jpg are no valid URLs and hence illegal.

Try file:g:/test.jpg instead.

Usually, the icons should be bundled with your application, so simply put the image file into your classpath (e.g. if you're using eclipse, put it into your 'src' directory) and use it like that:

stage.getIcons().add(new Image("/logo.jpg"));

use 

stage.getIcons().add(new Image(("file:logo.png")));

and put the image logo.png in root of your project ( at same directory where src )
