[rkward-users] Compatibility between RKWard and RGtk2

[Nicolas Chapados]

Hello all,

I'm a new RKWard user and so far I've been quite pleased with the
environment it provides for R development.  However, I'm wondering if
the compatibility with RGtk2 has been tested.  The following simple
program crashes RKWard with a SIGABRT ::

    require(RGtk2)
    require(gWidgets)
    require(gWidgetsRGtk2)
    options("guiToolkit" = "RGtk2")
    gbutton("Hello world", container=gwindow())

(I would gladly use Qt widgets within R, but there does not appear to
be any suitable bindings available.)
I am running under Ubuntu 9.04 and RKWard 0.5.1.  Here is the traceback I get ::
