I am using opengl to create a canvas where 2 Dimensional shapes can be dragged around. I thought of using the jit.gl.handle object but I don't want the objects to rotate, just drag. Is there a way to tell the object not to allow rotation? (or a different way of acheiving this?) I can't see anything to suggest there is in the documentation. If so, is there also a way of getting the object to drag without having to hold the shift/apple key?

in that case you can build it yourself from the mouseposition:

since jit.gl.handle only generates control messages you can easily  
filter out the rotation with [route]

Thats great. Thanks. Should really have thought of that. My only problem now is making it affect only one of multiple slabs.

I have a feeling that I am going about this completely wrong. Essentially what I am trying to do is create something that works similar to the tcl/tk canvas widget (if you know the one). My requirements are only in 2 dimensions so maybe I'm over complicating it by using openGL.

Allow Drag but disable rotation using jit.gl.handle
