Building tkentry dynamicly
Dear R-users,
I would like to build N "tkentry" compounds in the same window, with
default text for each. As N is variable I need to construct them in an
iterative way :
library(tcltk)
main<-tktoplevel()
tktitle(main)<-"My Tool"
filenames<-c("toto","tata","titi")
N<-length(filenames)
for (i in 1: N) {

re trieve user input from an tcl/tk interface
Hello everyone,
this is my first post here and I hope I signed up correctly and someone will

set tkscale by tkentry
Hi, I am working under Windows and I am using R2.11
I want to use tkscale in my GUI. As the interval is quite big, I can't set
the scale to a certain specific value. Therefore I want to add tkentry to
allow the user to set tkscale to a certain value.
Here is the code
library(tcltk)
tt<-tktoplevel()
tkpack(m1<-tkscale(tt,from=306870.00, to=3026741, label="alpha",

[macosx] improving quartz & Aqua Tk behaviour outside of RGui
Hello,
On Mac OS X, certain Aqua/Quartz UI functionality requires an
application to be launched from within an app bundle, or
(alternatively) requires a Carbon application with a resource fork.
Playing with the wxWidgets distribution, I discovered that it is quite
easy and transparent to make such a Carbon app from (I guess) any
command line application. When applied to the R executable called

Help with readBin
I'm trying to read a binary file created by a fortran code using readBin
and readChar. Everything reads fine (integers and strings) except for
double precision numbers, they are read as huge or very small number
(1E-250,...). I tried various endianness, swap, But nothing has worked so
far.
I also tried on R 64 bit for linux and windows (R 2.14) and R 2.11 on
windows XP 32 bit.

tkentry that exits after RETURN?
I can set up an entry widget (thanks to an old
post by Barry Rowlingson) that gets a password and
exits when the user clicks on the "OK" button.
Anyone have any clever ideas for returning/
destroying the window when the user types a carriage
return/ENTER in the text window? I've messed around
a little with validate, validatecommand, but don't
see any obvious way to do it ...

Masked user input
Hi -
I'm creating a package of database tools. A function in the package
requires the username and password as input to the function in order to
initially connect to the target database(s). Of course, this poses a
significant security issue given the possible retention of the function
statement in cleartext. I did not readily encounter a package meant to mask
input from the user nor do I

R tcl/tk
Friends:
I am a long-time R user, learning tcl/tk, and am tying myself in knots over
something that should be simple.
I want to create a frame and put that frame inside the toplevel frame.
This works (i.e. it places text in col 1, and the corresponding entry box in
column 2) and later frame.2 resides where it should in the toplevel frame.

autofill for a tkentry field
Hello all,
I'm experimenting with tlk/tk and I find it very useful. I would like to
have the text of a tkentry be automatically filled when the user starts
typing, according to a predetermined list. I've found a solution on the
tcl wiki pages, but I don't quite know how to translate it in R... Here is
the tcl code: http://wiki.tcl.tk/13267
And here is my code that does not work.

Error in as.environment(pos): using 'as.environment(NULL)' is defunct
Hello,
I?m using R 2.11.1 with Tinn-R 1.17.2.4.
I hope the given informations are enough (it?s my first entry here)
The as.environment(pos) error appears in using the following code which
should open a function in an other R-file.
Here some extractions of the code:

tkentry-element)

Question about unicode characters in tcltk
hello list,
Can someone help me figure out why the following code doesn't work?
I'm trying to but both Greek letters and subscripts into a tcltk menu.
The code creates all the mu's, and the 1 and 2 subscripts, but it
won't create the 0. Is there a certain set of characters that R won't
recognize the unicode for? Or am I input the \u2080 incorrectly?

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

Retrieving data from a tcl /tk function

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:

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')

rerender tcltk toplevel
Hi everybody,
I am trying to write a simple progress display based on a tcltk
toplevel. My first approach was to use the progressBar widget from the
BWidget library but since this is not available on every system (missing
on at least almost all windows systems, I guess...) I wanted to have a
backup there. So my second strategy was to use a simple toplevel with a
label and update the tclvariable
