Dear All,

Could anybody help me how to set the cursor in jogl2 when using native window?

Thanks in advance!

#2

sry for my ignorance but how native windows can be used ?

See demos.GLInfo code from Jogl2.0 demo src.

I think whenever it is possible Jogl2 will use the new native window automatically. But I know it not exactly, because with Jogl2 I have only experience on the local PC.

The cursor changing seems to work in the normal awt way.

This sample works for me:

package test;

import java.awt.Frame;
import java.awt.Point;
import java.awt.event.WindowAdapter;
import java.awt.event.WindowEvent;
import java.awt.image.BufferedImage;
import java.io.IOException;

import javax.imageio.ImageIO;
import javax.media.opengl.GLAutoDrawable;
import javax.media.opengl.GLEventListener;
import javax.media.opengl.awt.GLCanvas;

import com.sun.opengl.util.Animator;


public class Test implements GLEventListener {

	public static void main(final String[] args) {

		final Test test = new Test();
		final Frame frame = new Frame();
		final GLCanvas canvas = new GLCanvas();
		final Animator animator = new Animator(canvas);
		

		// cursor changing
		try {

			final BufferedImage cursorImg = ImageIO.read(test.getClass().getClassLoader().getResourceAsStream("fancy/cursor.png"));
			canvas.setCursor(canvas.getToolkit().createCustomCursor(cursorImg, new Point(), ""));

		} catch (final IOException e) {
			e.printStackTrace();
		}

		
		canvas.addGLEventListener(test);

		frame.add(canvas);
		frame.setSize(300, 300);		
		frame.addWindowListener(new WindowAdapter() {
			
			@Override
			public void windowClosing(final WindowEvent e) {

				new Thread(new Runnable() {
					public void run() {
						
						animator.stop();
						System.exit(0);
						
					}
				}).start();
				
			}
		});
		
		frame.setVisible(true);
		animator.start();
		
	}

	@Override
	public void init(final GLAutoDrawable drawable) {

		System.out.println(drawable);
		//results in: AWT-GLCanvas[ class javax.media.nativewindow.awt.AWTGraphicsConfiguration...

	}

	@Override
	public void display(final GLAutoDrawable drawable) {}

	@Override
	public void dispose(final GLAutoDrawable drawable) {}

	@Override
	public void reshape(final GLAutoDrawable drawable, final int x, final int y, final int width, final int height) {}

}

i know i have been using JFrame-based rendering for years, but native windows would give much better performance, that is why i would like to use it…

Thanks anyway!

If you guys have some code for ‘setCursor’ then feel free to add it to NEWT’s Window class - would be awesome !
For the native X11, MacOSX, Windows and AWT … implementation.
Volunteers ?
Send me your git branch location :slight_smile:
