Michael is right. There are other ways to include a file chooser, especially in
RGtk2. I think Antje was using the tcltk version though. Anyways, here are some
ways:

gfile() will open a dialog
gfilebrowse() adds a button to initiate the dialog

or as Michael points out, one can put in a RGtk2 object into gWidgets via the
add method:

w <- ggroup("test")
g <- ggroup(cont = w)
add(g, gtkButton("new button")

but this isn't working directly for some reason with the file chooser widget.
But putting into an intermediate Hbox  works:

g <- ggroup(cont = T)
fc <- gtkFileChooserWidgetNew("GTK_FILE_ACTION_SAVE")
g1 <- gtkHBox(); g1$Add(fc)
add(g, g1, expand=TRUE)
