Recommended Posts

Hello everybody!

This question is probably more LWJGL related, but i could not find already existing answer, so i will ask it here:

How to change cursor icon, to one of ones predefined by system?

In this case, i want to be able to change cursor icons to width=23 height=23http://www.useragentman.com/blog/wp-content/uploads/2011/12/move_cursor.png[/img] or 153.gif.

Because i have gui elements that can be moved and resized, and i want to change cursor icon when user can move or resize element.

 

Thanks for help!

If you have any questions - just ask!

2 Things:

1) This result isn't even on first page for me (google, what the heck?).

2) It's for swing. 100%. And minecraft is lwjgl.

 

Also, i do know that i can ship my mod with cursor image, then load it to int buffer, then create new cursor from this image, and bind this cursor... But, i know that system has predefined cursor icons, so i would like to use those.

Odd, was the first result for me.

Anyway, try this instead

That's better. But i have to ship cusor with mod...

 

Wait, found something: http://freewindowsvistatutorials.com/whereAreCursorsStoredLocationOfMousePointersFolderInWindows7.php

Now if i could get this folder on every os, and transform .cur into png to load...

Just ship the png.  It's 3 kilobytes.

Well, that didn't work. zY3gsqS.png

Code:

public static final Cursor defaultCursor;
public static final Cursor moveCursor;
public static final Cursor resizeCursor;

static {
	defaultCursor = Mouse.getNativeCursor();
	try {
		ResourceLocation texture = new ResourceLocation(ForeverEnoughItemsBase.MODID, "textures/cursors/move.png");
		InputStream s = Minecraft.getMinecraft().getResourceManager().getResource(texture).getInputStream();
		ByteArrayOutputStream bout = new ByteArrayOutputStream();
		IOUtils.copy(s, bout);
		byte[] b = bout.toByteArray();
		IntBuffer buf = ByteBuffer.wrap(b).asIntBuffer();
		moveCursor = new Cursor(23, 23, 11, 11, 1, buf, null);
	} catch(Exception e){
		throw Throwables.propagate(e);
	}
	/*try {
		ResourceLocation texture = new ResourceLocation(ForeverEnoughItemsBase.MODID, "textures/cursors/resize.png");
		InputStream s = Minecraft.getMinecraft().getResourceManager().getResource(texture).getInputStream();
		ByteArrayOutputStream bout = new ByteArrayOutputStream();
		IOUtils.copy(s, bout);
		byte[] b = bout.toByteArray();
		IntBuffer buf = ByteBuffer.wrap(b).asIntBuffer();
		resizeCursor = new Cursor(32, 32, 15, 15, 1, buf, null);
	} catch(Exception e){
		throw Throwables.propagate(e);
	}*/
	resizeCursor = defaultCursor;
}

Had to comment out resize cursor, because it can't be loaded by throwing exception.

Made some progress, still not working: PxRXxR0.png.

Code:

			ResourceLocation texture = new ResourceLocation(ForeverEnoughItemsBase.MODID, "textures/cursors/move.png");
		InputStream s = Minecraft.getMinecraft().getResourceManager().getResource(texture).getInputStream();
		BufferedImage image = ImageIO.read(s);
		ImageIO.write(image, "png", new File("move.png"));
		IntBuffer buf = IntBuffer.allocate(image.getWidth() * image.getHeight() * 4);
		for(int x = 0; x < image.getWidth(); x++){
			for(int y = 0; y < image.getHeight(); y++){
				int offset = x * (y * image.getHeight()) * 4;
				int argb = image.getRGB(x, y);
				buf.put(argb);
			}
		}
		buf.rewind();
		moveCursor = new Cursor(23, 23, 11, 11, 1, buf, null);

(Unfortunately aside from googling "how do I change the cursor" I am unable to help)

I have been googling whole day, and all results are either for swing, or not for something else but lwjgl. There were couple that were for lwjgl, but they aren't working.

 

Meanwhile, i found that in native open gl, there is GLUT, with

[url=https://www.opengl.org/documentation/specs/glut/spec3/node28.html]glutSetCursor[/url]

. Meanwhile, whole GLUT is not ported to java by LWJGL and nobody knows why.

 

Thanks for help anyways!

Maybe somebody else will be able to help.

Windows only supports cursors with dimensions multiple of 16.

Alright, that explains everything... And it's working...

 

Here's working code, if you're interested:

	public static final Cursor defaultCursor;
public static final Cursor moveCursor;
public static final Cursor resizeCursor;

static {
	defaultCursor = Mouse.getNativeCursor();
	try {
		BufferedImage image = ImageIO.read(Minecraft.getMinecraft().getResourceManager().getResource(new ResourceLocation(ForeverEnoughItemsBase.MODID, "textures/cursors/move.png")).getInputStream());
		moveCursor = new Cursor(image.getWidth(), image.getHeight(), image.getWidth() / 2, image.getHeight() / 2, 1, IntBuffer.wrap(image.getRGB(0, 0, image.getWidth(), image.getHeight(), null, 0, image.getWidth())), null);
	} catch(Exception e){
		throw Throwables.propagate(e);
	}
	try {
		BufferedImage image = ImageIO.read(Minecraft.getMinecraft().getResourceManager().getResource(new ResourceLocation(ForeverEnoughItemsBase.MODID, "textures/cursors/resize.png")).getInputStream());
		resizeCursor = new Cursor(image.getWidth(), image.getHeight(), image.getWidth() / 2, image.getHeight() / 2, 1, IntBuffer.wrap(image.getRGB(0, 0, image.getWidth(), image.getHeight(), null, 0, image.getWidth())), null);
	} catch(Exception e){
		throw Throwables.propagate(e);
	}
}

public static void setCursor(Cursor cursor){
	try {
		Mouse.setNativeCursor(cursor);
	} catch(LWJGLException e){
		Throwables.propagate(e);
	}
}

 

I'm going to go rage quit now.
