similar to: set tkscale by tkentry

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 ...

Hello, I want to plot several lines to a main plot but at the end of each loop, it erases the last one.

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) {

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 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

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.

Hi thank you for talking the time to help me with this. I have a sequence of numbers in a file and an equal sequence of various character, say(a b c d) each occurs more than once. I need to plot the numbers so that numbers corresponding to a in the other sequence would have green dots, those corresponding to b a red dot, nothing on c and blue square for d. i.e 2 a show a green dot 4 b show a

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 to all, I don't know almost nothing about Tcl/TK. I have the follow code: >Name <- tclVar("") >insert.Name <-tkentry(window1,width="20",objectvariable=Name) >tkplace(tklabel(window1,text=" Enter the matrix name:"),x=0,y=0) >tkplace(insert.Name,x=175,y=0) So, I need to pass the variable Name like parameter in R function. Ex:

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

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

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.

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. tkgrid(tklabel(frame.2, text="FACTOR column

Hi, I have a large plot that I would like to display in a graphics device with scroll bars. I therefore decided to use the windows function like so... mag<- length(tick) windows(height=mag/8, width=10, rescale="fixed") However, when I use the scroll bars the device (i guess) is re-drawing the plot. Is there any way in which I can get it to 'smooth scroll'? Kind regards,

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.
