Hi, I am trying to create a drop-down combobox in R TclTk. The following works fine for a ListBox but fails for a combobox: ################# THIS WORKS FINE - CREATES AN EMPTY LISTBOX ## tt<-tktoplevel() win <- .Tk.subwin(tt) .Tcl(paste("listbox",.Tk.ID(win),.Tcl.args())) tkpack(win) ################## THIS FAILS - ATTEMPTS TO CREATE A COMBOBOX ## tt<-tktoplevel() win

Hi, I'm using R version 2.9.0 and I'm trying to execute an example using tabnotebook from iwidgets. Unfortunately I get a problem as you can see bellow: > library(tcltk) Loading Tcl/Tk interface ... done > library(tkrplot) > tclRequire("Iwidgets") <Tcl> 4.0.1 > > tt <- tktoplevel() > tkpack(tn <- tkwidget(tt, "iwidgets::tabnotebook"))

Hi, I have successfully installed R 1.7.0 and ActiveTcl 8.4.2.0 in Windows 2000. Yes, I know that Tcl is already bundled with R 1.7.0, but I want to use the iwidgets package to create a drop-down listbox, and I don't think iwidgets is included in the bundled R 1.7.0/TclTk installation package. I have set the environment variables TCL_LIBRARY and MY_TCLTK to the directory where I

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 found here: http://bioinf.wehi.edu.au/~wettenhall/RTclTkExamples/DropDown.html . What I want to do is in that example get fruitChoice as a variable in R in general. When I run that code, however, and the ask for fruitChoice it says

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! The IWigdets::combobox has an option "selectioncommand" to specify a procedure which is called when an item in the combobox is selected. Does ComboBox from Bwidgets have an equal option or is there a simple method to do thi? I haven't found one but i would like to use Bwidgets instead of Iwidgets. Another question which should not be a problem, but at the moment I just

Hello, I have a problem with using Iwidgets in R while i'm able to use BWiget and Tktable. If I let tcl list the names of packages, Iwidgets seems available. I use R 2.6.0; in addition addTclPath("C:/Tcl/lib") has been used (in which iwidets is present) > try(tcl("package", "names")) <Tcl> http opt tcltest ::Utility::expand Widget ::Utility::number

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

Hello, I am exploring the TCLTK package under R and try to load and use additional TCL libraries (under Windows, with TCL8.3). For example : > addTclPath("C:/TCL/lib/bwidget1.5") > tclRequire("BWidget") <Tcl> 1.5 Loading seems to work, but when I try to create a specific widget : # The main window appears correctly > top=tktoplevel() # Trying to insert a

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 (

if I wanted to set the value of a combobox tt <- tktoplevel() box <- tkwidget(tt,"ComboBox",values=c(1,2,3)) tkgrid(box) tcl(box,"setvalue","first") does anybody know how I would access an index other than the first? as second, and numbers do not work.. thanks in advance Andreas Posch

Hi I've a problem with the following example: library(tcltk) .Tcl("array unset tclArray") myRarray <- matrix(1:1000, ncol=20) for (i in (0:49)) for (j in (0:19)) .Tcl(paste("set tclArray(",i,",",j,") ",myRarray[i+1,j+1],sep="")) tt<-tktoplevel() table1 <- tkwidget(tt,"table",variable="tclArray",

Hello, I'm trying to write a function using tcltk to interactively modify a plot and gather locator() data. I've read Peter's articles in Rnews, the help pages in tcltk, http://bioinf.wehi.edu.au/~wettenhall/RTclTkExamples/, plus a post in R-help sometime ago, but haven't found a solution. The idea goes something like this: require(tcltk) testplot <- function() { getcoords

Hello; Well, I'm afraid this is the second related problem I report in two days (I'm sorry for this) I've programmed a tcltk interface for a model and it includes a comboBox. The comboBox widget comes with the "BWidgets" library of Tcl/Tk. It works all perfectly with the windows R GUI (with the help of Prof. B. Ripley), following the advices in ?Startup, but I would like

Hi, all, (sessionInfo at the end) I've been struggling with the tcltk package and can't seem to get the ttkcombobox to work. Here's an example: library(tcltk) p <- tktoplevel() l <- tclVar() ## I don't know if I'm even calling it correctly cb <- ttkcombobox(p, values = letters[1:4], textvariable = l) tkpack(cb) 1. How do I know when the value of the combobox has

Hi, I've been learning how to use R TclTk in Windows over the last few months. I have recently put together a collection of examples of some common widgets and their corresponding R code, at http://bioinf.wehi.edu.au/~wettenhall/RTclTkExamples/ I would be interested in any feedback - Is it useful? Does it contain any significant errors or bad coding style? Does anyone else want to

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, 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)
