JavaFX Application Icon

Question

Is it possible to change the application icon using JavaFX, or does it have to be done using Swing?

Answer 1

Assuming your stage is "stage" and the file is on the filesystem:

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

As per the comment below, if it's wrapped in a containing jar you'll need to use the following approach instead:

stage.getIcons().add(new Image(<yourclassname>.class.getResourceAsStream("icon.png")));

Answer 2

I tried this and it totally works. The code is:

stage.getIcons().add(
   new Image(
      <yourclassname>.class.getResourceAsStream( "icon.png" ))); 

icon.png is under the same folder as the source files.

Answer 3

Full program for starters :) This program sets icon for StackOverflowIcon.

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

public class StackoverflowIcon extends Application {

    @Override
    public void start(Stage stage) {
        StackPane root = new StackPane();
        // set icon
        stage.getIcons().add(new Image("/path/to/stackoverflow.jpg"));
        stage.setTitle("Wow!! Stackoverflow Icon");
        stage.setScene(new Scene(root, 300, 250));
        stage.show();
    }

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

Output Screnshot

Updated for JavaFX 8

No need to change the code. It still works fine. Tested and verified in Java 1.8(1.8.0_45). Path can be set to local or remote both are supported.

stage.getIcons().add(new Image("/path/to/javaicon.png"));

OR

stage.getIcons().add(new Image("https://example.com/javaicon.png"));

Hope it helps. Thanks!!

Answer 4

you can add it in fxml. Stage level

<icons>
    <Image url="@../../../my_icon.png"/>
</icons>

Answer 5

If you have have a images folder and the icon is saved in that use this

stage.getIcons().add(new Image(<yourclassname>.class.getResourceAsStream("/images/comparison.png")));

and if you are directly using it from your package which is not a good practice use this

stage.getIcons().add(new Image(<yourclassname>.class.getResourceAsStream("comparison.png")));

and if you have a folder structure and you have your icon inside that use

stage.getIcons().add(new Image(<yourclassname>.class.getResourceAsStream("../images/comparison.png")));

Answer 6

What do you think about creating new package i.e image.icons in your src directory and moving there you .png images? Than you just need to write:

Image image = new Image("/image/icons/nameOfImage.png");
primaryStage.getIcons().add(image);

This solution works for me perfectly, but still I'm not sure if it's correct (beginner here).

Answer 7

stage.getIcons().add(new Image(<yourclassname>.class.getResourceAsStream("/icon.png")));

If your icon.png is in resources dir and remember to put a '/' before otherwise it will not work

Answer 8

stage.getIcons().add(new Image(<yourclassname>.class.getResourceAsStream("/icon.png" )));

You can add more than one icon with different sizes using this method.The images should be different sizes of the same image and the best size will be chosen. eg. 16x16, 32,32

Answer 9

stage.getIcons().add(new Image(ClassLoader.getSystemResourceAsStream("images/icon.png")));

images folder need to be in Resource folder.

Answer 10

You can easily put icon to your application using this code line

stage.getIcons().add(new Image("image path") );

Answer 11

stage.getIcons().add(new Image("/images/logo_only.png"));

It is good habit to make images folder in your src folder and get images from it.

Answer 12

I used this in my application

Image icon = new Image(getClass().getResourceAsStream("icon.png"));
window.getIcons().add(icon);

Here window is the stage.

Answer 13

stage.getIcons().add(new Image(("nospaniol/ui/icons/nospaniol.png")));

Answer 14

If you run the jar file, the code specified by Michael Berry will change the icon in the title bar and in the taskbar. Shortcut icon cannot be changed.

If you run a native program compiled with com.zenjava, You must add a link to the program icon:

<plugin>
<groupId>com.zenjava</groupId>
<artifactId>javafx-maven-plugin</artifactId>
<version>8.8.3</version>
<configuration>
...
<bundleArguments>
   <icon>${project.basedir}/src/main/resources/images/filename.ico</icon>
</bundleArguments>
</configuration>
</plugin>

This will add an icon to the shortcut and taskbar.

Answer 15

I tried this and it works:

stage.getIcons().add(new Image(getClass().getResourceAsStream("../images/icon.png")));

Answer 16

If you got Invalid URL or resource not found put your icon.png in the "bin" folder in your workspace.

Answer 17

Another easy way to insert your own icon on the title bar in JavaFX is to add the image to your primary stage using the following method:

Image ico = new Image("resources/images/iconLogo.png");
stage.getIcons().add(ico);

Make sure your import javafx.scene.image.Image (if using an ide like netbeans this should be automatically done for you).
