tcltk: Difficulties creating menus
I am struggling with adding menus to a tcltk application. The following
example (from the O'Reilly book on Perl/Tk) works fine:
#!/usr/bin/perl -w

my $mw = MainWindow->new;
$menub = $mw->Menubutton(-text => "Color")->pack();
foreach (qw/red yellow green blue grey/) {

Hi,
I'm posting yet another question about tcltk since I'm still struggling
with the package. I'm trying to create a tklistbox and a ttkcombobox on

tklistbox...
Hi everyone,
I have different listboxes in the same toplevel window.
The problem is, if I select (by left clicking) one of those listbox
elements, the current selection in the other listboxes is cleared!
Anybody knows how I can prevent this?
Thanks,

tkinsert (PR#4289)
In R-1.7.1, I used to be able to append a character vector to a 'tklistbox' with e.g.
listio <- tklistbox( tktoplevel(), font='Courier', height=20, width=20, setgrid=TRUE)
tkinsert( listio, 'end', letters[1:3])
tkpack( listio,side='left', expand=TRUE, fill='both')
and three items would be added to 'listio'. This doesn't work in R-devel-- it

tcltk scrollbar
The following code should give me (at least that's what I think) two list
boxes with their individual scrollbars. But instead both scrollbars stick to
the same listbox even though they work as they should (scroll individual
listboxes). When I remove all the widgets on top everything works perfectly.
Any help would be highly apprecciated.
ps: all subsequent listboxes and scrollbars work

tklistbox and extracting selection to R
Dear experts,
I am trying to understand why is it that when I paste (into the R console) the following code to select an option from a list:
require(tcltk)
tt<-tktoplevel()
tl<-tklistbox(tt,height=ntx,selectmode="single",background="white")
tkgrid(tklabel(tt,text="Select the legend of" ))

I created a listbox, no problem. Then I bind the Button-1 of the mouse to the listbox to start some things by pressing the mousebutton. The proiblem is that as I click a item of the listbox this error occured:
Error in .Tcl(.Tcl.args(...)) : [tcl] bad listbox index "": must be active, anchor, end, @x,y, or a number.

Scrolling a tkcanvas non-starter
Hello,
Is it possible to scroll a canvas that has a column of listboxes in it? Does scrolling only work with listboxes and text widgets?
The following code displays the scrollbar, but
- it has no thumb
- does not respond to mouse clicks.
- the vertical height of the tkcanvas (i.e. column1) is unconstrained. It's lower edge is out of view, and the lower button on the scrollbar is out of

Resolved tklistbox selection problem
Turns out I needed to add "exportselection=0". So:
foo.lb <- tklistbox(root, height = 5,
selectmode = "extended", exportselection = 0)
Got this from:
http://tolstoy.newcastle.edu.au/R/e2/help/06/12/6955.html
(That's what I get for assuming there'd be no tcl/tk questions on this
list. D'oh!)
Cheers!

tcltk: multiple listboxes, selection
Dear list,
I have multiple (BWidget) listboxes in the same toplevel window.
The problem is, if I select (by left clicking) on one of those
listbox elements, the current selection in the *other* listboxes is
cleared!
Anybody knows how I can prevent this?
Here's my code (sorry not complete):

stuck tcltk scrollbars under Windows XP
Dear R-devel list members,
I've encountered a problem with my Rcmdr package under Windows XP and could
use some advice:
The Rcmdr package uses the tcltk package to create menus and dialog boxes.
My standard procedure when a dialog is created is to grab the focus -- e.g., by
tkfocus(top)
tkgrab(top)
(Here, top is a top-level window -- say, containing one or more
scrollbars.)

Loading tcltk package fails on WinMe/Cygwin but works with Rgui
I am investigating how well R/tcltk is supported on different system and I
ran into the same problem as Christian Schulz reported on February 7, 2002.
I am using [R] v1.4.1 on WinMe and ActiveTcl 8.3.2. Loading tcltk within
Rgui works just fine and both demo(tkdensity) and demo(tkttest) works as
expected. However, when I start R from my Cygwin terminal dyn.load() fails
to load the library:
