Hi,

I want to put a ggobi display into a GUI window setup by gWidgets, but error
occur said it is not a S4 object.

Does anyone have any idea about how to put it in or maybe it can not be put
into a widget at all?

Thanks A LOT!

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)

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.

Here is some code to grab the display for a new display. I don't know
how to get the initial display or even how to suppress it, but I'm
not a ggobi user at this point.

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

x <- ggobi(mtcars)
## not sure how to get the initial display,
## here we create a new display and move that
disp <- display(x[1]) ## see display.GGobiData

## find table in the display heirarchy
table <- disp[[2]]

## plot is third child (rulers are first two)
plotWidget <- table[[3]]$getWidget()
table$remove(plotWidget)
## hide window that held display. Destroy() causes errors
disp$getParent()$hide() 

## now we need to declass things so that gWidgets will 
## recognize. The S3 classes from RGtk2 that gWidgets 
## knows about are declared in package (should be 
## dynamic, but aren't)

class(plotWidget) <- class(plotWidget)[-(1:3)]

w <- gwindow("A gwidget's window")
g <- ggroup(cont = w, expand=TRUE)
add(g, plotWidget, expand=TRUE)
