[R-gui] Post hoc tweeking of ggenericwidget?

[christiaan pauw]

Hi Everybody

ggenericwidet in the gWidgets package is really handy - you can get a
basic gui for your function in just about no time. Now I just want to
tweek it a little bit. For example: I want to use gvarbrowser to
select x . Can this type of object be manipulated after the initial
creation or must be all be done when it is created? If

In the process of trying to ascertain this, I tried to see the
structure of the object created by ggenericwidget. This is what
happened:
x=ggenericwidget("boxplot.default", container=TRUE)  # example from
the help file
str(x)
      # I am trying to use str() to see the structure of x so that I
can figure out how to manipulate certain aspect

Error in function (classes, fdef, mtable)  :
  unable to find an inherited method for function ".length", for
signature "gGenericWidgetANY", "guiWidgetsToolkitRGtk2"

Is this a problem in my system or is the object not accesable to str() ?

Thanks in advance
Christiaan
