hello, i would like program userfriendly tcl/tk widgets like the t-test example in a more complex way ! (1) Is it not possible to combine tk_getOpenFile with the R function read.table to select in userfriendly way data sets ? (I'm newbie and take code-parts from t-test example and scripting example.) (2) Is it possible to use a variableSelection widget to select a special variable which i

Actually I am trying to run sciview-R and encounted some problems with tk, and I thought I'll check the basic library(tcltk) functionallity, just to be sure. Anybody seen that '[tcl] bad window path name ".1".' message before? Prof. Philippe Grosjean: yes, I have managed to load most of sciview-R under Wine, except the tcltk library! =================== R : Copyright 2005,

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

Hello companions!!! I have a function that creates a Radio Buttons, and I need that this function return the selected value in the Radio Buttons. I would like that, if somebody know as I could return the value, you say me as do it. Next, I show the function function1<-function(){ require(tcltk) tt <- tktoplevel() rb1 <- tkradiobutton(tt) rb2 <- tkradiobutton(tt) rbValue <-

Hello everyone, this is my first post here and I hope I signed up correctly and someone will take me by the hand and help me out. I am new to R and cannot figure out what to do here... ... I want to have an User Interface that requests input. I want to save this input to a variable to use it later on. I was able to do this with a modalDiaglog (

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?

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() tkwm.deiconify(dlg)

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

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')

Hello, I took me very long to find out how to set the initial value in the combobox widget in tk (see the example below). My question is now : Why does "textvariable" has to be a tclVar while "values" can be a normal vector? My next question is: How could I have known this much earlier? Is there a documentation for the tcl/tk usage in R? I know a lot of website with example.

Hello, I wrote a function in R which uses tcltk package .... essentially I wanted to give within that function, a widget with 2 radiobuttons to choose between plotting Precip and Temperature plots. After the user has chosen one of the radiobuttons there is another widget that asking him to identify outliers. However, I am having a lot of problems...what R does is evaluate the whole function

Dear list, Could somebody who is more experienced with the Tcl/Tk interface from R please help me clarify the issues I've put below with ### --> tags? Several things go wrong, and it's probably because of messy code, but I have a difficult time finding out what is the cause. Thanks very much, JeeBee. require(tcltk) || stop("Package tcltk is not available.") # Add path to

Hi, All: I am having a problem with handling global variable value in GUI programming, I hope R gurus can give me some advice on it. What I want to do is to read in a dataset, display some information based on the input and do some calculation on the dataset: However, I am having trouble organizing my code, as the following code goes, the comboBox section will have to be put in the

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

I searched the web and the list archives for a solution to this, but didn't see anything, so here goes. I'm new to tcltk. I'm trying to change the contents of a tkentry widget when a button is pressed. Once I get that working, the widget will be read only to the user. Here is some toy code: ############### require(tcltk) thisEnv=environment() tt<-tktoplevel() Name <-

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.

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) {

Hi List, Can anyone tell me how could i put the "BACK" button in the following code, just under the "AAA" menu? I want this button to go back to the previous page, and since it has nothing to do with the "1" and "2" buttons, i want it somehow separated from these two buttons, but i don't know how. I searched the web for some examples but my results

Hi I am trying to insert a jpeg into a widget I have created. I have used this link http://bioinf.wehi.edu.au/~wettenhall/RTclTkExamples/showImage.html to display a jpeg inside a newly created widget but would like some info on how to insert into a pre existing widget. This is my code below for my first widget. tt<-tktoplevel() fontHeading2 <-
