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')

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

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 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

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 it wanted to add a boton of checkup in a menu, ?How I do to create so many variables as checkbutton? I try with the code that continues, use a vector that is charged dynamicamente while I open files but the component of vector "b" is associates with a Tcl variable and load 3 components (environment, value and pointer) I wanted alone to charge the value (0 done not select

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

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

I am struggling with adding menus to a tcltk application. The following example (from the O'Reilly book on Perl/Tk) works fine: #!/usr/bin/perl -w use Tk; my $mw = MainWindow->new; $menub = $mw->Menubutton(-text => "Color")->pack(); foreach (qw/red yellow green blue grey/) { $menub->radiobutton(-label => $_, -command => \&set_bg,

Hi, I am working under Windows and I am using R2.11 I want to use tkscale in my GUI. As the interval is quite big, I can't set the scale to a certain specific value. Therefore I want to add tkentry to allow the user to set tkscale to a certain value. Here is the code library(tcltk) tt<-tktoplevel() tkpack(m1<-tkscale(tt,from=306870.00, to=3026741, label="alpha",

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. If you press HALLO it prints HALLO WORLD. Not exciting, but I need an example... set tt [toplevel .tt] foreach i {"hello" "HALLO"} { pack [button $tt.b$i -text $i

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)

Within a loop I tried to draw some things in dependency on the position of the mouse. This works fine with R-1.5.1 but R-1.6.1 requires to include some delay by Sys.sleep(delay) with delay>=0.015. For smaller values (e.g. 0.0001) the top level tcltk-window does not appear and so I am not able to control the elements to be plotted using the tcltk-widget. Question1: How can I force

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 <-

I was trying to write a small routine using the tcltk library which allows a little bit of interaction with a plot. Basically, using the function locator(1), a user could click on an area of a graph which would cause a little tcltk window to pop up. When they have finished with the window, they click on a tcltk button, the window disappears, allowing the user to select another point on the graph
