Many thanks! Added to tcltk2 1.1-1 (in a slightly different form). It
should shortly appear on CRAN.

Hey Philippe,
I have a question concerning an tk2mclistbox problem.
I have the same problem as in this post you commented.
https://stat.ethz.ch/pipermail/r-sig-gui/2009-February/000911.html
It was dated Feb.09. The sample code still throws an error.
Are there any advances? Right now it seems the tk2mclistbox cannot
be used?!
I tried to fix the problem, but it appears to be a bug in a Tk widget
that is not maintained any more (mclistbox). At the time I integrated
it in tcltk2, it was fully functional. At this point, there are three
possibilities:
1) To use a Tktable widget instead (also supported by tcltk2),
2) To use the newer tablelist Tk widget, but that requires some work
to incorporate it in tcltk2 (http://wiki.tcl.tk/5527; the best choice
I think),
3) To fix the old mclistbox widget (we need a good Tcl programmer here).
If someone wants to submit a patch for #3, or work on a solution for
#2, I will gladly include it in tcltk2.
Best,
Philippe Grosjean
Am I wrong? What can I do?
Thanks in advance!!
Mark

I also had this problem.
I found out that the error occurs in the tcl procedure
'::tk::ListboxBeginSelect', so i rewrite it (removing the part where the
error occurs, which was only an additional condition here *).
Run the following in R before creating the listbox:
string = 'proc ::tk::ListboxBeginSelect {w el {focus 1}} {
variable ::tk::Priv
if {[$w cget -selectmode] eq
"multiple"} {
if {[$w selection includes $el]} {
$w selection clear $el
} else {
$w selection set $el
}
} else {
$w selection clear 0 end
$w selection set $el
$w selection anchor $el
set Priv(listboxSelection) {}
set Priv(listboxPrev) $el
}
event generate $w <<ListboxSelect>>
if {$focus && [winfo exists $w] *}
{ focus $w
}
}'
.Tcl(string)
I am not a skilled tcl programmer, it was only an experiment and for me
it worked good.
Maybe it also helps you.
