Because in for loop i is overwritten every time - as you said i=3 is
the last command.
Replacing for with sapply should fix it:
require(tcltk)
OK.but <- NULL
PressedOK <- function(i)
{
tkmessageBox(message=paste("You pressed OK!",i,sep=""))
}
tt <- tktoplevel()
sapply(1:3,function(i){
OK.but[[i]] <- tkbutton(tt,text="OK",command=function()PressedOK(i))
tkgrid(OK.but[[i]])
})
tkfocus(tt)
