Hello companions!!!
I have a function that creates a Radio Buttons, and I need that this
function return the selected value in the Radio Buttons. I would like that,
if somebody know as I could return the value, you say me as do it.
Next, I show the function
function1<-function(){
require(tcltk)
tt <- tktoplevel()
rb1 <- tkradiobutton(tt)
rb2 <- tkradiobutton(tt)
rbValue <- tclVar("oranges")
tkconfigure(rb1,variable=rbValue,value="apples")
tkconfigure(rb2,variable=rbValue,value="oranges")
tkgrid(tklabel(tt,text="Which do you prefer?"))
tkgrid(tklabel(tt,text="Apples "),rb1)
tkgrid(tklabel(tt,text="Oranges "),rb2)
value<-0;
aux_function<- function()
{
rbVal <- as.character(tclvalue(rbValue))
tkdestroy(tt)
if (rbVal=="apples")
tkmessageBox(message="Good choice! An apple a day keeps the
doctor
away!")
if (rbVal=="oranges")
tkmessageBox(message="Good choice! Oranges are full of Vitamin
C!")
print(rbVal);
return(rbVal);
}
OK.but <- tkbutton(tt,text="OK",command=function() aux_function())
#OK.but <- tkbutton(tt,text="OK",command=function()
value<<-aux_function())
tkgrid(OK.but)
tkfocus(tt)
#return(value)
}
Thanks in advance!
A greetings Luismi
