tklistbox - R-Objekt
Hello, I have a problem with a tklistbox. The user should be able to choose
one out of two calculation methods needed for further calculations. My
r-script for that purpose looks like that:
require(tcltk)
tt<-tktoplevel()
tl<-tklistbox(tt,height=4,selectmode="single",background="white")

Problem with tcltk listbox
Hi!
I've got two problems with listboxes and selection:
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.

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" ))

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.)

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...
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,

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!

disappearing dialog boxes when using tcltk
Dear all,
I'm trying to use tcltk to build a small
user-interface and couter the problem:
It seems that sometimes the dialog box will be
minimized automatically though I want it to be on top
of the screen all the time.
For example, when runing the following code, if you
type in "a1", "a2", "a3", etc when being asked for an
integer, the program is supposed to

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):
(E.g. If I select an X value, I'd lose the Y value I selected before)

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

Problem with geometry manager in TclTK
Hello, everyone.
I have the following problem with TclTk: I create some windows and want to
change their position with geometry manage (sometimes they will be centered,
sometimes not).
If the toplevel is created and its dimensions are gathered via 'tkwinfo', I
get (usually) correct values. However, if this window is created by a
function (in the following example, by 'ask.format')

Double-clicking in tk list dialogs
Am I the only one who finds himself futilely double-clicking a CRAN
mirror in the dialog for choosing a CRAN mirror? Yes, double-clicking
works in Windows, but not in the Tk-based dialog on Linux. I'm going
to wear out my mouse button.
Adding the following line to the tk_select.list function in the tcltk
package adds double-click functionality to list dialogs:

tklistbox selection
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
the same parent and am having a problem. Here's an example:
library(tcltk)
tt <- tktoplevel()
tcl1 <- tclVar()
tcl2 <- tclVar()
tclObj(tcl1) <- letters[1:5]
tclObj(tcl2) <- LETTERS[1]

Retrieving data from a tcl /tk function
Hello,
I am sorry if this is an answered question, but I did my homework for a long while and couldn't figure out a way to retrieve data entry from a model dialog. In one of the examples compiled by James Wettenhall:
odalDialog <- function(title, question, entryInit, entryWidth = 20,
returnValOnCancel = "ID_CANCEL") {
dlg <- tktoplevel()

tcltk in BATCH mode
DeaR list,
I am writing a user friendly script for an interactive use of R. The user is
supposed to click on a bat-File in Windows-environment and to enter some
values in a pop-up window.
Let us assume we have the script given below. If she sources this script
within R, everything works smoothly. The pop-up window jumps and patiently
waits her to enter the value. For this to work she has to start

tk + browser() can leave R unresponsive
I don't know if this is a bug. I can reproduce the following on Ubuntu
12.04.2 and 13.04 64-bit with R version 3.0.1 and with r63479. There
is no difference if R is patched with the fix for PR#15407 or not,
although without the fix there are more ways to trigger this.
I can reproduce with the following:
1. Open R in gnome-terminal or xterm
2. Run 'library(tcltk)'
3. Run

Dropdown boxes in tcltk and R
Hello,
I'm very much a newbie in R and more so in tcltk so apologies if this
question is stupid. Basically I am trying to use the combobox example

What I want to do is in that example get fruitChoice as a variable in R

tcl/tk return problem

sound silly to most of you.
