Hi David,
forgot to mention I use the RGtk2 GUI toolkit.
options("guiToolkit"="RGtk2")
Under tcl I do not get this results neither. Under RGtk2 I do (Mac
OS 10.6.1, R 2.10.0 32-bit).
Any ideas?
I don't have anything constructive to offer. Any time I try to run a
package that depends on Gtk2+ I fail at some point in ways that seem
to depend on compilation options or resources that I do not have
correctly arranged in my libraries. My questions to the R-Mac-SIG list
list seem to be taken as evidence of irremediable *NIX cluelessness.
So I have decided to spend my time on other, more productive pursuits.

Can't reproduce. On a Mac 10.5.8, R 2.10.1, running the 64 bit GUI,
after choosing the gWidgetstcltk option for GUI toolkit when
gwindow() is first executed, I do not get a behavior that suggests
that the table handler gets executed twice with each button click.
I get an X11 window with a button across the width of the top of
the window. Each time the button is clicked I get :

addhandlerclicked button
addhandlerclicked table
Just for fun I modified your tbl handler and got sensible
incrementing highlighting of the rows with:
> addhandlerclicked(b, handler=function(h, ...){
+ cat("addhandlerclicked button\n")
+ svalue(tbl, index=T) <- 1+svalue(tbl) # the earlier code did not
change values
+ })
I want it to be executed only once. Does someone know, why this
happens and how I can change it?
library(gWidgets)
w <- gwindow()
b <- gbutton("press", cont=w)
tbl <- gtable(1:10, cont=w)
addhandlerclicked(b, handler=function(h, ...){
cat("addhandlerclicked button\n")
svalue(tbl, index=T) <- 1 # change the table
value
})
addhandlerclicked(tbl, handler=function(h, ...){
cat("addhandlerclicked table\n")
})
Thanks!
