Hi John,

Thanks A LOT for your reply and the code. What I want to do is to include the ggobi display window to the widget window setup by me. I tried add before but it said can not do it for GGobiScatterplotDisplay. Do you have any idea about add displays?

Thanks again for your help.

To embed a GTK widget into gWidgets isn't too hard, just call the add method. 
I'm not sure how  to get the GTK object you want from the ggobi 
interface. Below is an example that you might be able to modify: 

## 
library(RGtk2) 
library(rggobi) 
library(gWidgets) 
options(guiToolkit="RGtk2") 

## ggoobi object 
x <- ggobi(mtcars) 

## grab child from main window. Modify (how?) to get 
## other widgets 
toplevel <- ggobi_gtk_main_window(x) 
child <- toplevel[[1]]  # toplevel has only one child 
toplevel$remove(child)  # remove child if keeping toplevel 
toplevel$destroy()      # or destroy if not 

## add to a gWidget instance using gWidgetsRGtk2: 
w <- gwindow("A gwidget's window") 
g <- ggroup(cont = w, expand=TRUE) 
add(g, child, expand=TRUE)
