R help - Dec 2009 - gWidgets / RGtk2 - how to change a handler from a toolbar?

I want to assign a default handler to a toolbar button and change the  
handler later.
The addhandlerclicked() method does not apply to a gAction Object, I  
think...

defHandler <- function(h, ...) print("default")	
w <- gwindow()			
aTest <-  gaction(label="Test", icon="open",
handler=defHandler)
tblList = list( test = aTest )
toolBar = gtoolbar(tblList, cont=w)

At this point I would like to change the handler from the aTest object.
Does someone know?

TIA
Mark

There should be a method to do this, but for now there isn't. A workaround
would
be to have the default handler call a function which can be redefined during the
flow of the program:

f <- function(h,...) print("default")
defHandler <- function(h, ...) f(h,...)

The RGtk2 way would be to remove the handler and add a new one, but even that
isn't so easy, as the id isn't stored at the moment.
