To whoever is looking for the same thing as I was, I found a solution, or
sort of.
Here is the code:
flavors<-c("vanilla", "chocolate", "strawberry")
w <- gwindow("checkbox example")
gp <- ggroup(container=w)
glabel("Favorite flavors:",cont=gp)
cbg <- gtable(flavors, cont=gp, multiple=T)
# Here is the trick
addHandlerClicked(cbg,handler=function(h,...){
My_Flav<-svalue(cbg)
print(My_Flav)
})
Select multiple lines, and you shall see all the selected rows.
