R help - Dec 2011 - RGtk2: How to overlay a gtkDrawingArea with a button or any other widget?

I try to overlay a plot inside a gtkDrawingArea with a button (or any other
widget).
I tried to put both into a gtkFixed container.
But this does not work, no printing occurs.
Does someone know a solution?

What I tried:

w <- gtkWindow()
w$setSizeRequest(400,400)
fx <- gtkFixed()
da <- gtkDrawingArea()  
fx$put(da, 100, 100) 
asCairoDevice(da)  
par(mar=c(0,0,0,0))
plot(1:10)  
btn.1 <- gtkButton("button")
fx$put(btn.1, 200, 200)   
w$add(fx) 

Thanks
Mark

Sorry for the late reply to this one. You'll need to make sure that the
drawing area is realized prior to plotting, i.e., it should be in a visible
container. Also, since you are using GtkFixed, you will need to set an
explicit size request on the drawing area (otherwise it has zero area).
