POHow to make JOGL 2.0 work with SWT?
text
Body
copied!<p>I'm trying to get SWT working with the newest JOGL (2.0).</p> <p>I tried <a href="http://dev.eclipse.org/viewcvs/index.cgi/org.eclipse.swt.snippets/src/org/eclipse/swt/snippets/Snippet209.java?view=markup" rel="nofollow noreferrer">SWT snippet 209</a>, but it doesn't work. The problem is caused by the following line:</p> <pre><code>final GLContext context = GLDrawableFactory.getFactory().createExternalGLContext(); </code></pre> <p>...but when I change <code>getFactory()</code> to <code>getFactory(GLProfile.getDefault())</code> (to make it compatible with the new API), it crashes on <code>createExternalGLContext()</code> with <code>javax.media.opengl.GLException: Error: current context null</code>. I don't understand this message: I'm trying to create a new context, and it complains that the current is null. Why?</p> <p>Maybe there is some other way to create a <code>GLContext</code>?</p> <p>Or maybe it is possible to use <code>GLEventListener</code> with SWT <code>GLCanvas</code>?</p> <p>PS. I placed my modified version of the snippet <a href="http://m01.pastebin.com/1JW3CCxi" rel="nofollow noreferrer">here</a>.</p> <hr> <p>Edit: now I understand the error message. <a href="http://jogamp.org/deployment/jogl-next/javadoc_public/javax/media/opengl/GLDrawableFactory.html#createExternalGLContext%28%29" rel="nofollow noreferrer">Documentation</a> says:</p> <blockquote> <p>The underlying OpenGL context must be current on the current thread at the time this method is called.</p> </blockquote> <p>How to create the first <code>GLContext</code>?</p>
