So this wasn't tested for a month? Anyways, Free() is just free() with a check that we're not freeing a null pointer, followed by setting the pointer to NULL. At that point of tcltk.c, we have for (objc = i = 0; i < length(avec); i++){ const char *s; char *tmp; if (!isNull(nm) && strlen(s = translateChar(STRING_ELT(nm, i)))){ // tmp =

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 ...

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

Hello all, using package tcltk this is my problem: I want to set a colour of a tclVar(). I have a tklabel (fixed in position) which should display two variables occasionally. If a constraint is fulfilled, the tklabel should display correct<-tclVar('correct') in green, otherwise it should display wrong<-tclVar('wrong') in red! To display the variables is no

Dear R-help list members, I'm writing a package using tcltk. Thanks to Peter Dalgaard's excellent work on the tcltk package, almost everything has gone very smoothly. I'm stymied, however, by the following problem: I want to incorporate a bitmap image, stored as an xbm file, in a widget. To take a simple example, top <- tktoplevel() tkgrid(tklabel(top,

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

Not happening on Mac, so likely a Windows build issue.

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)

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? library(tcltk) m

Hi. I'm running into problems with using R functions as callback commands for buttons in Tk. The following Tcl/Tk script creates three buttons. If you press hello it prints hello world.

I think I - almost - got the knack for GUI programming using the tcltk library.

Hello I have been playing with tcl/tk in R 2.4.0 on windows XP and have managed to crash R by supplying tcl/tk with an incorrect color.
