1. I want to change the mouse cursor over my window into a wait/watch icon while R computes. Can this be done directly? Some ancient tcltk mailing lists said change the cursor over every widget in the window: foreach widget [winfo children $window] { $widget config -cursor watch } To do this I'll need a list of

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. 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')

I am the maintainer of a Bioconductor package (affylmGUI) which uses tcltk. It freezes inconsistently on MS Windows, but not Mac or Unix. see details below. After considerable testing I have reduced the problem from a few thousand lines of code to 30 lines! If you paste the following lines of code into an R window: testGUI <- function(){ require(tcltk) MainWindow <-

Hello, I am trying to setup a menu to open files and directories. I have the following code: opendir<-function() { dirname<<-tclvalue(tkchooseDirectory()) } openfile<-function() { filename<<-tclvalue(tkgetOpenFile()) } require(tcltk) t1<-tktoplevel() topMenu<-tkmenu(t1) tkconfigure(t1,menu=topMenu) plotMenu<-tkmenu(topMenu, tearoff=FALSE)

IIRC, the license stated in the source code of dataplot is rather restrictive. I don't think one is allowed to use the source as can be done with GPL code.

I've been able to figure out on my own how to do what I need in the largely undocumented tcltk package, but I've finally hit a wall. I can't even think of any sufficiently specific search terms to use for this. I'm trying to make the widgets in my tk window resize when the window is resized by clicking and dragging on its corners or edges. Instead they stay exactly where they

Dear list members, I and my students have encountered an intermittent problem using the Rcmdr package (version 0.9-0) under Windows (with the SDI). The problem occurs both in versions 1.7.1 and 1.8.0 of R. The problem seems to occur only in the following context: The "Edit data set" button is pressed in the Rcmdr GUI. This executes the fix() function on the active data frame,

Dear gurus: I have a question on how to configure the margin layout on tcl/tk GUI objects like tkcanvas, tkframe or tktoplevel. For example, if I want to leave a larger margin on the left side of the GUI container, which one should I configure, the toplevel or tkcanvas or tkframe? top<-tktoplevel() canvas<-tkcanvas(top, relief=, borderwidth=...) I also find the documentation for all

Dear Professor I have read your questions in the website on Doubly non-central F-distribution. I am looking for source code for evaluating this function now. I have matlab code but it's only accurate up to the 4th decimal point. Dataplot is more accurate, but it is not user friendly as you only can evaluate one function at a time. So I would like to know do you have found any R code for

Dear all I'm developing a grafical interface for Geneland that is presently one of the R packages available. My first question is about refreshing the interface while running a very long process. run<-function(){ ? ? ? ? tttry <- tktoplevel() ? ? ? ? tkwm.geometry(tttry, "+200+200") ? ? ? ? tkwm.title(tttry,"wait") ? ? ? ?

Have a look at the GUI on dataplot, NIST's plotting software. It is implemented in tcl/tk. The site states it is "public domain software" -- open source? I can't find anything about the license. In any case... http://www.itl.nist.gov/div898/software/dataplot/ Brett A. Magill, Evaluator Research, Assessment, and Evaluation Saint Louis Public Schools Brett.Magill at

Dear list members, Rich Heiberger reported to me last week that the Messages window in the Rcmdr GUI was freezing -- that is, messages posted to this window didn't appear -- under Windows and R 2.8.0. I was able to confirm this problem on three Windows systems, one using Vista and the other two XP. In each case, I used R 2.8.0 and Rcmdr 1.4-4 (the current version). The problem doesn't

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. Repaeting

Thanks everybody for looking at this. I am trying to assign a script to a button please help: ############ library(tcltk) tt<- tktoplevel() tktitle(tt)<-"the title" heading<-tklabel(tt,text="Enter date as YYYY-MM-DD") l1<-tklabel(tt,text="Reporting date") b1=tkbutton(tt,text="Run") d.val<-tkentry(tt,width=12) tkgrid(heading,columnspan=2)

Why the variable archOp does not take the value that be chosen in the menubutton?, therefore always remains as a white one, I intend to charge the direccion of open files in a vector and then to elect with the menubutton with which to work but not functions thanks.Ruben library(tcltk) arch<-tclVar(init=" ") archOp<-tclVar(init=" ") vectPath<-c()

The following R code works as expected: require( tcltk ) tt <- tktoplevel() # create a button labelled A that changes to B when pressed pressed <- function() tkconfigure( tt.but, text="B" ) tt.but <- tkbutton( tt, text="A", command=pressed ) tkpack(tt.but) # if Control-Button-1 pressed change button label to C e <- expression( tkconfigure( tt.but,

Dear R-Users, Being an engineer and not a statistician, my desired course of action may either be impossible or very simple. I am attempting to fit a non-linear model to some measured data. One term in the model contains a square-root, but in the course of regression, this term turns negative and an error occurs. I started using Micrsoft's Excel Solver, and then I turned to NIST's

Hello there, I'm struggling with the base graphics system on different operating systems. I would like to get an animation effect by re-plotting with the plot function. See the attached code example: move the slider quick from one side to the other. I experience different levels of success, depending on which OS I use. - Linux (Ubuntu >9.10, R 2.9.2-3): Each plot command gets

Hi! I've constructed a small menu-driven interface to a couple of R functions using the possibilities offered by the tcltk package. When user runs some specific analyses, I would then like to disable some of the menus (or menu choises) that are not applicable after the performed analysis. I tried to modify the state of an existing menu, but it seems that neither tkconfigure nor
