Dear Florian, you may want to look at the gWidgetstcltk package which makes such
things a bit easier than plain tcltk. Here is one way with a modal dialog:
f <- function() {
library(gWidgets)
options("guiToolkit"="tcltk")
dlg <- gbasicdialog()
tbl <- glayout(cont = dlg)
tbl[1,1] <- "trials"
tbl[1,2] <- (trials <- gedit("100", coerce.with=as.numeric, cont = tbl))
tbl[2,1] <- "Stimuli"
tbl[2,2] <- (stimuli <- gedit(10, coerce.with=as.numeric, cont = tbl))
visible(dlg, set=TRUE)
return(sapply(list(trials, stimuli), svalue))
}
