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

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 everyone, I have different listboxes in the same toplevel window. The problem is, if I select (by left clicking) one of those listbox elements, the current selection in the other listboxes is cleared! Anybody knows how I can prevent this?

Dear list, I have multiple (BWidget) listboxes in the same toplevel window. The problem is, if I select (by left clicking) on one of those listbox elements, the current selection in the *other* listboxes is cleared! Anybody knows how I can prevent this? Here's my code (sorry not complete): (E.g. If I select an X value, I'd lose the Y value I selected before) gui.create.tab.general <-

The following code should give me (at least that's what I think) two list boxes with their individual scrollbars. But instead both scrollbars stick to the same listbox even though they work as they should (scroll individual listboxes). When I remove all the widgets on top everything works perfectly. Any help would be highly apprecciated. ps: all subsequent listboxes and scrollbars work

Hello, very basic question from a user who is baffled by the workings of computers in general When logging off R, a dialog box asked if I wanted to save my log, I chose yes. Then I noticed that the following message appeared in the Command Window Error in saveLog(currentLogFileName) : unused argument(s) ("C:/Documents and Settings/prewpj/My Documents/Data/Analyses/Healthcare/Hand Care

Dear experts, I am trying to understand why is it that when I paste (into the R console) the following code to select an option from a list: require(tcltk) tt<-tktoplevel() tl<-tklistbox(tt,height=ntx,selectmode="single",background="white") tkgrid(tklabel(tt,text="Select the legend of" )) tkgrid(tl) treatments<<-levels.tx for(i in

Hello, I have a problem with a tklistbox. The user should be able to choose one out of two calculation methods needed for further calculations. My r-script for that purpose looks like that: require(tcltk) tt<-tktoplevel() tl<-tklistbox(tt,height=4,selectmode="single",background="white") tkgrid(tklabel(tt,text="select method for LAI

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

Hey folks, This is my first message to the mailing list so please let me know if I mess something up. I'm trying to use the selectcommand for the mclistbox but I'm not very adept at using functions. Ideally I'd like to change the editor text when a different list item is selected but any help using the selectcommand would be appreciated and I think I could get the rest working.

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 <-

Hi there, I need to build up a tktext-widget that contains a longer text than the tktext-widget actually is. So what I mean is, that the tktext window is of width=100 and the text in it has a length greater 100. But I don't want the window to just wrap the line, but to belong to scrollbar that is able to scroll to the end of the text. tt <- tktoplevel() txt <- tktext(tt,

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

I everyone, i have a little problem with tklistbox,the " " character and Rcmdr. Please look at this code require(tcltk) tt<-tktoplevel() levels.list2 <-tklistbox(tt,selectmode="multiple",exportselection="FALSE", height=4, yscrollcommand=function(...)tkset(levels.list2.scroll,...))

Dear r-devel list members, I've experienced the following problem in getting a selection from a Tk list box using tcltk. This is a long-standing problem, but I've finally decided to tackle it. Consider the following: Library(tcltk) top <- tktoplevel() listbox <- tklistbox(top, height="10", width="2", exportselection="FALSE",

Dear List, I'm looking for some informations about the function "tkinsert()". I d'like to write lot of command in my text window and after to evaluate it with a button "Submit" for example, but i have some problems: here a exemple of my code: 1) My first problem tt=tktoplevel() txt=tktext(tt,height=40) tkpack(txt) var1=paste("x=2")

dear list, I have problems with tkinsert I need to display a matrix as a result of my function, but when I use tkinsert(txt, "end", myMatrix, sep="\n") I simply obtain a string. I do: n<-tclVar() tclObj(n)<-matrix(data, ncol=lenght) tkinsert(txt, "end", tclvalue(n), sep="\n") any hints? thank you in advance, simone gabbriellini

Dear R-devel list members, I've encountered a problem with my Rcmdr package under Windows XP and could use some advice: The Rcmdr package uses the tcltk package to create menus and dialog boxes. My standard procedure when a dialog is created is to grab the focus -- e.g., by tkfocus(top) tkgrab(top) (Here, top is a top-level window -- say, containing one or more scrollbars.)

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
