JavaFx Title Bar Image comes up black all the time

After researching quite a bit of the posts and trying everything out, I am out of options on my own to do a task as simple as setting an icon on the title bar using eclipse IDE and Java FX 2.

It either comes up with the default empty window icon or comes back black. Please let me know what I am doing wrong.

Here are some of my attempts,

//Image ico = new Image(UI.class.getResourceAsStream("Sunset.jpg"), 16, 16,      true,true);        
//Image ico = new Image("Sunset.jpg", true);// looks inside src folder
//primaryStage.getIcons().add(new Image(UI.class.getResourceAsStream("/title.jpeg")));
//primaryStage.getIcons().add(new Image(UI.class.getResourceAsStream("title.jpeg")));

Image ico = new Image(UI.class.getResourceAsStream("Sunset.jpg"));
primaryStage.getIcons().add(ico);

I have tried the following with the pictures I have been using,

  1. I used pictures with attributes 300x300 pixels
  2. I converted pictures which were 300x300 pixels to 16x16 pixels
  3. I used *.ico with both 32x32 and 16x16 pixels
  4. I converted .ico into jpeg and tried as well.

Please let me know, how I can overcome this. Thanks !

This bug can be reproduced even on Windows 7 if you put the monitor in the 16 bit operating mode: Screen Resolution -> Advanced Settings -> Monitor (tab) -> Colors = 16 bit

Seems like the issue has been filled into the JavaFX tracker here: https://javafx-jira.kenai.com/browse/RT-28947 by Joe S. from the other answer, but I won't bet on having it fixed in JDK8.

The cause seems to be a potential bug in JavaFx. If you have your system set to anything below 32-bit color you will get black boxes for your taskbar and title bar icons. Setting your system to 32-bit color will fix it.

The following works for me:

Image image = new Image(<some valid image location here>);
stage.getIcons().setAll(image);

Here is a sample app:

import static javafx.application.Application.launch;
import javafx.application.*;
import javafx.scene.Scene;
import javafx.scene.image.*;
import javafx.scene.layout.VBox;
import javafx.stage.Stage;

public class IconApp extends Application {
  @Override public void start(Stage stage) {
    Image image = new Image(
      "http://icons.iconarchive.com/icons/tooschee/misc/128/Present-icon.png"
    );
    stage.getIcons().setAll(image);

    final VBox layout = new VBox(10);
    layout.setStyle("-fx-background-color: cornsilk; -fx-padding: 10;");
    layout.getChildren().setAll(new ImageView(image));

    stage.setScene(new Scene(layout));
    stage.show();
  }

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

// icon license (creative commons 3 with attribution): 
//   http://creativecommons.org/licenses/by-nc/3.0/
// icon attribution: 
//   http://tooschee.com/portfolio?worksCategory=icons

And the output of the app (you can see the stage icon in the top left corner of the title bar):

presenticon

The icon also shows up in the operating system task bar:

presenticonintaskbar

Test system was Windows 7, Java 8b77.
