OSX 10.10.2
R 3.1.3
XQuartz installed.
I am trying to run one of the tcltk demos
This one works:
tt <- tktoplevel()
label.widget <- tklabel(tt, text = "Hello, World!")
button.widget <- tkbutton(tt, text = "Push",
command = function()cat("OW!\n"))
tkpack(label.widget, button.widget) # geometry manager
# see Tk-commands
But the next one breaks:> if(as.character(tcl("info", "tclversion")) >=
"8.5") {
+ # make use of themed widgets
+ # list themes
+ as.character(tcl("ttk::style", "theme",
"names"))
+ # select a theme -- here pre-XP windows
+ tcl("ttk::style", "theme use", "winnative")
+ } else {
+ # use Tk 8.0 widgets
+ }
Error in structure(.External(.C_dotTclObjv, objv), class = "tclObj") :
[tcl] bad command "theme use": must be configure, map, lookup,
layout, theme, or element.
What is going wrong here?

Thesw are demos for tclscrollbar I copied them from the help file to the console manually as the help file suggested.> On 12 Mar 2015, at 09:04, peter dalgaard <pdalgd at gmail.com> wrote: > >> >> On 11 Mar 2015, at 23:41 , Erich Neuwirth <erich.neuwirth at univie.ac.at <mailto:erich.neuwirth at univie.ac.at>> wrote: >> >> OSX 10.10.2 >> R 3.1.3 >> XQuartz installed. >> >> I am trying to run one of the tcltk demos > > Which demos?

Sorry,
I get at these demo when I do
?tkscrollbar
Then the help file for many of the UI widgets appears, titled
TkWidgets {tcltk}
On the bottom of this file are the 2 examples I mentioned.
Excuse the incomplete description in the first and the incorrect description in
the second message.
