callback environment for Tk buttons
Hi. I'm running into problems with using R functions as callback
commands for buttons in Tk.
The following Tcl/Tk script creates three buttons. If you press hello
it prints hello world. If you press HALLO it prints HALLO WORLD.
Not exciting, but I need an example...
set tt [toplevel .tt]
foreach i {"hello" "HALLO"} {
pack [button $tt.b$i -text $i
