Try `tkraise`:
library(tcltk)
w1 <- tktoplevel()
tkpack(ttkbutton(w1, text="w1", command=function() {
tkraise(w2)
}))
w2 <- tktoplevel()
tkpack(ttkbutton(w2, text="w2", command=function() {

Re: [R] Help with Using gtext in gWidgetsWWW for Outputting Results to Webpage
Ron Fricker nps.edu> writes:
Ron,
A few things.
I am in the process of rewriting this package to use the new Rook package.
The current package is on r-forge as gWidgetsWWW2. It works for local use,
but Rook isn't yet integrated in with rapache to serve in a public way.
(https://r-forge.r-project.org/R/?group_id=761)
Second, the gtext widget has two methods for setting the text: svalue<- will
replace the current text, and sounds like what you want. The insert method
can be used to add to the current text, either at the beginning or
end (It just calls svalue in the end). It sounds like you are using insert.
Third, I had some issue with "\n" in the text, so added a call to some
internal method stripSlashN to replace \n with . That might not be
working for you. You can try to replace these yourself. The fact that
gWidgetsWWW uses proto (gWidgetsWWW2 doesn't) means you can
hack some things. Here you can bypass the stripSlashN call by
redefining the method, doing something like:
t <- gtext("", ) ## your usual call
t$setValueJS <- function(.,...) {
out <- sprintf("%s.setValue('%s');", .$asCharacter(), .$..data)
return(out)
}
You might need some other function wrapping .$..data, which stores the
raw data. (The \n caused problems when passed back to the browser.
The gWidgetsWWW2 implementation bypasses this, so should work better
going forward.)
Finally, the font stuff isn't implemented. I think (but didn't check) you can
use HTML markup within your text.
Feel free to email directly if you want to.

The callback is expecting two variables to be passed in. If you aren't
going to use them, just put ... in the signature:
window1_delete_event <- function(...) print('Work or dont work???')

Along those lines, in addition to the above mentioned packages, you might want to look at some packages that use cairoDevice to create interactive graphic displays.

If you don't mind installing the GTK libraries, then the traitr package can be
used here without too much difficulty. Here is what you can do for your request
(a stripped down version of a demo in the vignette)
## sample data, replace me
d <- data.frame(country=c("US","US","Canada","Mexico"),
x = rnorm(1:4),
y = rnorm(1:4))
library(traitr)
library(gWidgets) ## also gWidgetsRGtk2, cairoDevice
options(guiToolkit="RGtk2")
countries <- unique(d$country)
dlg <- aDialog(items=list(
output=graphicDeviceItem(),
countryFilter=choiceItem(value=countries, values=countries,
multiple=TRUE, show_label=FALSE)
),
help_string="Use filter to narrow",
## this is called when the countryFilter checkbox is clicked
property_countryFilter_value_changed=function(.,...)
.$make_plot(),
## this draws the plot
make_plot=function(.) {
countries <- .$get_countryFilter()
## adapt this:
plot(y ~ x, data=d, subset=country %in% countries)
})
view <- aPanedGroup(aContainer("output"),
aFrame(label="Filter by:",
aFrame("countryFilter", label="Country")),
horizontal=TRUE
)
dlg$make_gui(gui_layout=view)
dlg$make_plot()

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))
}
