similar to: tklistbox and extracting selection to R

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 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,...))

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

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 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?

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, 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,

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",

I don't know if this is a bug. I can reproduce the following on Ubuntu 12.04.2 and 13.04 64-bit with R version 3.0.1 and with r63479. There is no difference if R is patched with the fix for PR#15407 or not, although without the fix there are more ways to trigger this. I can reproduce with the following: 1. Open R in gnome-terminal or xterm 2. Run 'library(tcltk)' 3. Run

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')

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

Hello everyone, this is my first post here and I hope I signed up correctly and someone will take me by the hand and help me out. I am new to R and cannot figure out what to do here... ... I want to have an User Interface that requests input. I want to save this input to a variable to use it later on. I was able to do this with a modalDiaglog (

Hello, I'm very new in working with tcl/tk in R and have a problem which will probably sound silly to most of you. Here is the code I have problems with: readcelfiles <- function() { require(tcltk) tt <- tktoplevel() tkgrid(tklabel(tt,text="Choose a directory!")) OnOK <- function() { fileDir<-tclvalue(tkchooseDirectory()) data.raw <-

Hi - I'm creating a package of database tools. A function in the package requires the username and password as input to the function in order to initially connect to the target database(s). Of course, this poses a significant security issue given the possible retention of the function statement in cleartext. I did not readily encounter a package meant to mask input from the user nor do I

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 <-

Hello, I use package "tcltk" to do some GUI programming, and want to find a function which can do the operation "click a button", just like using a mouse to click. If tkevent.generate can do that? I tried it as below, but failed. Please give me a hint! tt <- tktoplevel() tkwm.title(tt,"Simple Dialog") onOK <- function(){print("OK")} onCancel <-

I'm trying to read a binary file created by a fortran code using readBin and readChar. Everything reads fine (integers and strings) except for double precision numbers, they are read as huge or very small number (1E-250,...). I tried various endianness, swap, But nothing has worked so far. I also tried on R 64 bit for linux and windows (R 2.14) and R 2.11 on windows XP 32 bit. Any help would

In Windows, Tcl/Tk programs running under the tcltk package can update too frequently: for exmaple, we might go through a long sequence of operations to construct a complex display, and in Windows each addition will be shown separately. To work around this, I've added a function "tclServiceMode" which serves as an R interface to the "Tcl_SetServiceMode" function in the

What would be the best way to create a form select dropdown box and upon "submit" have it directly go to a controller method view? I have something that somewhat works, but I think there is probably a much easier way to do it. As of now, I have the dropdown list which when the form is submitted is handed to a controller method which basically I have my dropdown box: <%=

Dear list members, I've been puzzling over how best to clean up the code for my Rcmdr package. In particular, there's a lot of repetitive tcltk code in the package, and as Martin M?chler has pointed out to me, this makes the package difficult to maintain. If R were Lisp, I'd use macros for much of the clean up. My efforts to do similar things with R functions has run into problems
