Hi Rob That example was written using an earlier version of J and needs to be updated for J8. The problem is that painting commands were being given to an isigraph control before it was painted, whereas in J8, painting commands must be given in a paint event.
For current gl2 examples, try Help|Studio|Qt Demos|gl2 and Help|Studio|Showcase|isigraph.
