Display.setIcon on Macs

[elias4444]

Well, I got my Macbook Pro finally!  

I noticed however, that when I use the display.setIcon() command, it doesn't seem to work, although it works on windows and linux for me. Here's the code I'm using:

try {
			if (System.getProperty("os.name").startsWith("Mac OS")) {
				ByteBuffer[] icons = new ByteBuffer[1];
				BufferedImage bufferedImage1 = ImageIO.read(new BufferedInputStream(getClass().getClassLoader().getResourceAsStream("mainmenu/images/icon128.png")));
				icons[0] = convertImageData(bufferedImage1);
				Display.setIcon(icons);
			} else {
				ByteBuffer[] icons = new ByteBuffer[3];
				BufferedImage bufferedImage1 = ImageIO.read(new BufferedInputStream(getClass().getClassLoader().getResourceAsStream("mainmenu/images/icon16.png")));
				BufferedImage bufferedImage2 = ImageIO.read(new BufferedInputStream(getClass().getClassLoader().getResourceAsStream("mainmenu/images/icon32.png")));
				BufferedImage bufferedImage3 = ImageIO.read(new BufferedInputStream(getClass().getClassLoader().getResourceAsStream("mainmenu/images/icon128.png")));
				icons[2] = convertImageData(bufferedImage1);
				icons[1] = convertImageData(bufferedImage2);
				icons[0] = convertImageData(bufferedImage3);
				Display.setIcon(icons);
			}
		} catch (IOException e1) {
			e1.printStackTrace();
		}

and here's the convertImageData method I'm using (got it somewhere off this forum):

private ByteBuffer convertImageData(BufferedImage bufferedImage) { 
		ColorModel glAlphaColorModel = new ComponentColorModel(ColorSpace.getInstance(ColorSpace.CS_sRGB),
				new int[] {8,8,8,8},
				true,
				false,
				ComponentColorModel.TRANSLUCENT,
				DataBuffer.TYPE_BYTE);
		
		ColorModel glColorModel = new ComponentColorModel(ColorSpace.getInstance(ColorSpace.CS_sRGB),
				new int[] {8,8,8,0},
				false,
				false,
				ComponentColorModel.OPAQUE,
				DataBuffer.TYPE_BYTE);
		
		ByteBuffer imageBuffer = null; 
		WritableRaster raster;
		BufferedImage texImage;
		
		int texWidth = 2;
		int texHeight = 2;
		
		// find the closest power of 2 for the width and height
		// of the produced texture
		while (texWidth < bufferedImage.getWidth()) {
			texWidth *= 2;
		}
		while (texHeight < bufferedImage.getHeight()) {
			texHeight *= 2;
		}
		
		// create a raster that can be used by OpenGL as a source
		// for a texture
		if (bufferedImage.getColorModel().hasAlpha()) {
			raster = Raster.createInterleavedRaster(DataBuffer.TYPE_BYTE,texWidth,texHeight,4,null);
			texImage = new BufferedImage(glAlphaColorModel,raster,false,new Hashtable());
		} else {
			raster = Raster.createInterleavedRaster(DataBuffer.TYPE_BYTE,texWidth,texHeight,3,null);
			texImage = new BufferedImage(glColorModel,raster,false,new Hashtable());
		}
		
		// copy the source image into the produced image
		Graphics g = texImage.getGraphics();
		g.setColor(new Color(0f,0f,0f,0f));
		g.fillRect(0,0,texWidth,texHeight);
		g.drawImage(bufferedImage,0,0,null);
		
		// build a byte buffer from the temporary image 
		// that be used by OpenGL to produce a texture.
		byte[] data = ((DataBufferByte) texImage.getRaster().getDataBuffer()).getData(); 
		
		imageBuffer = ByteBuffer.allocateDirect(data.length); 
		imageBuffer.order(ByteOrder.nativeOrder()); 
		imageBuffer.put(data, 0, data.length); 
		imageBuffer.flip();
		
		return imageBuffer; 
	}

I should probably also mention, I'm assuming that the display.seticon method will change the dock's icon (since there is no "window icon" technically). If that's incorrect, please let me know.
