Re: [platform-swt-dev] Cocoa SWT GLCanvas Event Handling Problems

[Scott Kovatch <skovatch@xxxxxxxxx>]

Stefan,

Have you tried the 32-bit build? Or are you targeting 1.6?

Someone else here can correct me, but I¹m pretty sure you don¹t want to
create an NSOpenGLView directly. The SWT doesn¹t know it¹s a Widget subclass
so it won¹t receive SWT events. Instead you would use JOGL or a related
technology and wrap the GLCanvas around that. See this snippet:
<http://dev.eclipse.org/viewcvs/index.cgi/org.eclipse.swt.snippets/src/org/e
clipse/swt/snippets/Snippet209.java?view=co>  This is how I tested the
OpenGL support.
