[RQt-devel] "super" and "this" within scope of callbacks

[John Verzani]

 When defining classes and setting methods (qsetClass, qsetMethod) the
environment has the object "this" and "super" available to it. Would this be
possible within a callback set by qconnect? In RGtk2 and tcltk there is a
way to get the object within the callback without having to use global
variables or pass that object in through user.data.

E.g., something like this

b <- Qt$QPushButton("click me")
qconnect(b, "pressed", function(...) print(this$text))

It is easy enough to hack qconnect to add in "this" to the environment of
the handler, but I'm not sure how "super" would be done.
