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.)

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')

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

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)

Dear all, I'm trying to use tcltk to build a small user-interface and couter the problem: It seems that sometimes the dialog box will be minimized automatically though I want it to be on top of the screen all the time. For example, when runing the following code, if you type in "a1", "a2", "a3", etc when being asked for an integer, the program is supposed to

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 (

Dear R People: Hello! I'm putting together another RcmdrPlugin package and need to add a FORTRAN subroutine to speed things up a bit. I've never added compiled code to a package. Anyhow, I put my code into a /src directory. Here are the statements: * using log directory 'c:/R/R-2.11.1/bin/RcmdrPlugin.push.Rcheck' * using R version 2.11.1 (2010-05-31) * using session charset:

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

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",

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 <-

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

Hello all, I've had trouble converting a data.frame to a matrix (numeric) using either data.matrix() and as.matrix(). After executing one of those I end up with another data.frame with only the first column of the original data.frame. I use a window (tcltk) to let the user choose the columns he wants and then I retrieve them using the following: varstemp <-

I am the maintainer of a Bioconductor package (affylmGUI) which uses tcltk. It freezes inconsistently on MS Windows, but not Mac or Unix. see details below. After considerable testing I have reduced the problem from a few thousand lines of code to 30 lines! If you paste the following lines of code into an R window: testGUI <- function(){ require(tcltk) MainWindow <-

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 <-

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

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; I've got several radiobuttons in tcltk with the following sintaxis: tk2.rd <- /tkradiobutton(/frame4,command=plotDialog1,text="New Q plot", value=2, variable=OUTPLOTtclVar/)/ All the buttons call the same function "plotDialog1". With the objective of call a dialog to select some plotting options. When I select one of the radiobuttons and the windows with the

'tkcoords' is defined twice (in the same way) in src/library/tcltk/R/Tk.R. Attached is a patch against r63780 that removes the duplicate definition and alphabetizes the functions. I've read that minor patches such as this should be sent to r-devel [1]. Scott [1] http://permalink.gmane.org/gmane.comp.lang.r.devel/33987 -- Scott Kostyshak Economics PhD Candidate Princeton
