similar to: tcltk: multiple listboxes, selection

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? Thanks, --------------------------------------------------- Rita Sousa DME - ME: Departamento de Metodologia Estatística - Métodos Estatísticos INE -

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

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

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, Is it possible to scroll a canvas that has a column of listboxes in it? Does scrolling only work with listboxes and text widgets? The following code displays the scrollbar, but - it has no thumb - does not respond to mouse clicks. - the vertical height of the tkcanvas (i.e. column1) is unconstrained. It's lower edge is out of view, and the lower button on the scrollbar is out of

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.)

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

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, 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

Hi, I'm posting yet another question about tcltk since I'm still struggling with the package. I'm trying to create a tklistbox and a ttkcombobox on the same parent and am having a problem. Here's an example: library(tcltk) tt <- tktoplevel() tcl1 <- tclVar() tcl2 <- tclVar() tclObj(tcl1) <- letters[1:5] tclObj(tcl2) <- LETTERS[1] tb1 <- tklistbox(tt,

Turns out I needed to add "exportselection=0". So: foo.lb <- tklistbox(root, height = 5, selectmode = "extended", exportselection = 0) Got this from: http://tolstoy.newcastle.edu.au/R/e2/help/06/12/6955.html (That's what I get for assuming there'd be no tcl/tk questions on this list. D'oh!) Cheers! Mark -- I'm taking reality in

Hello, I took me very long to find out how to set the initial value in the combobox widget in tk (see the example below). My question is now : Why does "textvariable" has to be a tclVar while "values" can be a normal vector? My next question is: How could I have known this much earlier? Is there a documentation for the tcl/tk usage in R? I know a lot of website with example.

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.

Hello, I'm very much a newbie in R and more so in tcltk so apologies if this question is stupid. Basically I am trying to use the combobox example found here: http://bioinf.wehi.edu.au/~wettenhall/RTclTkExamples/DropDown.html . What I want to do is in that example get fruitChoice as a variable in R in general. When I run that code, however, and the ask for fruitChoice it says

Hi everybody, I am trying to write a simple progress display based on a tcltk toplevel. My first approach was to use the progressBar widget from the BWidget library but since this is not available on every system (missing on at least almost all windows systems, I guess...) I wanted to have a backup there. So my second strategy was to use a simple toplevel with a label and update the tclvariable

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, All: I am having a problem with handling global variable value in GUI programming, I hope R gurus can give me some advice on it. What I want to do is to read in a dataset, display some information based on the input and do some calculation on the dataset: However, I am having trouble organizing my code, as the following code goes, the comboBox section will have to be put in the

Hi everyone, I wonder if anybody observed the crash of the tkfilefind demo. I looked into the code and it seems to crash executing dirtree<-tkwidget(base, "hierarchy_dir", root=path, showparent="Parent", showfiles=1, showall=all.names,
