Java – Taskbar icon with lwjgl

javalwjgltaskbarwindowswindows 7

I want to add a taskbar icon for my running lwjgl process on Windows 7.

Display.setIcon changes successfully the icon in the topleft of the window, but not in the taskbar.

What do to?

My code, something like:

ArrayList<ByteBuffer> byteBuffers = new ArrayList<ByteBuffer>();
byteBuffers.add( ImageHelper.loadImageAsIconImage("stickmanicon32x32.png") );
byteBuffers.add( ImageHelper.loadImageAsIconImage("stickmanicon16x16.png") );
System.out.println( "taskbaricon result: " + Display.setIcon(byteBuffers.toArray(new ByteBuffer[]{})) );

I tried adding a 40×40 image too, but no change.

This code worked just fine for me. No need of extra libs.

ByteBuffer[] list = new ByteBuffer[2];
list[0] = createBuffer(ImageIO.read(new File("src/Images/Tests/icon16.png")));
list[1] = createBuffer(ImageIO.read(new File("src/Images/Tests/icon32.png")));
Display.setIcon(list);

Java – How to create an executable JAR with dependencies using Maven

<build>
  <plugins>
    <plugin>
      <artifactId>maven-assembly-plugin</artifactId>
      <configuration>
        <archive>
          <manifest>
            <mainClass>fully.qualified.MainClass</mainClass>
          </manifest>
        </archive>
        <descriptorRefs>
          <descriptorRef>jar-with-dependencies</descriptorRef>
        </descriptorRefs>
      </configuration>
    </plugin>
  </plugins>
</build>

and you run it with

mvn clean compile assembly:single

Compile goal should be added before assembly:single or otherwise the code on your own project is not included.

See more details in comments.

Commonly this goal is tied to a build phase to execute automatically. This ensures the JAR is built when executing mvn install or performing a deployment/release.

  <artifactId>maven-assembly-plugin</artifactId>

C# – Change pinned taskbar icon (windows 7)

EDIT The info below is a bit obsolete; all new Windows 7 bits are now available as a managed API, available here: http://code.msdn.microsoft.com/WindowsAPICodePack

There is a series of articles on the new Taskbar API by the debugging guru Sasha Goldshtein. You should have a look at the Overlay Icons and Progress Bars API.

You can download the sample code from Windows 7 Taskbar Developer Resources on Microsoft Code. What you're looking for is the IMClient sample:

The IMClient sample demonstrates how taskbar overlay icons and taskbar progress bars can light up an application’s taskbar button instead of relying on an additional dialog or on an icon in the system notification area (tray).

I believe this should help you achieve what you want.
