All,
I am using the tcltk package (under macos 10.3.8, running R from ESS, R
2.0.0). I am using tcltk libraries from fink:
i tcltk 8.4.1-12
Tool Command Language and the Tk toolkit
i tcltk-dev 8.4.1-12
Tool Command Language and the Tk toolkit
i tcltk-shlibs 8.4.1-12
Tool Command Language and the Tk toolkit
#### R CODE
PressedOK <- function()
{
plot(runif(100)*10,runif(100)*10)
}
tt <- tktoplevel()
OK.but <- tkbutton(tt,text="OK",command=PressedOK)
tkgrid(OK.but)
tkfocus(tt)
If I evaluate the above code, it works as expected. However, when
completed (I close the "OK" window), if I enter any commands that
result in errors by R (commands that don't exist, for example), I get:
> dev()
Error: couldn't find function "dev"
In addition: Warning messages:
1: X11 protocol error: BadWindow (invalid Window parameter)
2: X11 protocol error: BadWindow (invalid Window parameter)
3: X11 protocol error: BadWindow (invalid Window parameter)
4: X11 protocol error: BadWindow (invalid Window parameter)
5: X11 protocol error: BadWindow (invalid Window parameter)
6: X11 protocol error: BadWindow (invalid Window parameter)
7: X11 protocol error: BadWindow (invalid Window parameter)
8: X11 protocol error: BadWindow (invalid Window parameter)
However, as soon as I do ls(), for example, the warning messages
disappear and don't recur unless I re-execute the code. The archives
turned up this thread
(https://stat.ethz.ch/pipermail/r-help/2004-August/055212.html), which
relates to RCMDr use, but I think is probably general. The thread
doesn't look like it comes to a complete resolution. (I did one
suggestion, remove the tkfocus call, and get the same result.) I am
tempted to ignore the warnings entirely (being lazy when the code
works), but just wanted to hear if there are any insights from the
list.
Thanks,
Sean
