Michael, thanks for your answer!
The attribute solution has its problems though.
First, how it will work:
foo <- function(){
w <- gtkWindow()
da <- gtkDrawingArea()
w$add(da)
asCairoDevice(da)
print(dev.cur())
gObjectSetData(da, "dev.number", data = dev.cur())
dev.set(gObjectGetD
Currently, the GtkDrawingArea object has no real knowledge that it is being
used as a graphics device. You could do something like: stick the device ID
on da1/da2 as an attribute, and then have a function that does dev.set with
that attribute.

I am not too familiar with Cairo and RGtk2 and have the following problem:
I have a container with two GTK drawing areas converted into Cairo devices.
I know that I can set the current drawing context e.g. using dev.set().
But this is tedious. How can I set the context using the objects da1 or da2
