Q:

R with RGtk2: "Hello world" example using a GUI builder (glade, GTKBuilder)?

I want to create a GUI in R using RGtk2 and the Glade GUI builder as user interface designer.
How can I use the XML file created by Glade in my R code (using e. g. RGtk2)?
Has anybody a "hello world" example with a simple window or a link to a a good tutorial
THX!
PS: There is a code example in the documentation of RGtk2 but it does not work since the function "gladeXMLNew" is no longer available (see this post).
> GUI <- gladeXMLNew("applicationwindow1")
Error: could not find function "gladeXMLNew"

A:

User @nico pointed me to the solution:
library(RGtk2)
demo(builder)
# the variable "filename" points to a Glade XML file
# (which seems to be for Gtk2, not Gtk3 though)

Still an open question: Is there a good tutorial for Glade with RGtk2?
