Thank you for your reply. However, I don't quite understand.
The only snippet I could find was
http://dev.eclipse.org/viewcvs/index.cgi/org.eclipse.swt.snippets/src/org/eclipse/swt/snippets/Snippet275.java?view=co, and it doesn't use a LWJGL Display. Also, how can I use Display.setParent() on anything other than an AWT canvas when the method is defined as setParent(java.awt.Canvas parent)?
