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.

Dear R People: When will version 1.9 (for Windows) be ready, please? My reason for asking: there is an interesting library from Bioconductor called tkWidgets. However, it will only work with version 1.9.0 or higher. Are there ways around this, or should I just be patient? Thanks so much in advance!

Hi, The following code, from the examples in ?TkWidgets , immediately crashes R 4.0.1 for Windows: --------------------- snip -------------------- library("tcltk") tt <- tktoplevel() label.widget <- tklabel(tt, text = "Hello, World!") button.widget <- tkbutton(tt, text = "Push", command = function()cat("OW...

Hi, I'm using R version 2.9.0 and I'm trying to execute an example using tabnotebook from iwidgets.

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 <-

Hi I've a problem with the following example: library(tcltk) .Tcl("array unset tclArray") myRarray <- matrix(1:1000, ncol=20) for (i in (0:49)) for (j in (0:19)) .Tcl(paste("set tclArray(",i,",",j,") ",myRarray[i+1,j+1],sep="")) tt<-tktoplevel() table1 <- tkwidget(tt,"table",variable="tclArray",

Thanks Peter, I've started a new R session (in Windows) and managed to get both ways working now : ### THIS WORKS !!! ### library(tcltk) tclRequire("IWidgets") tt<-tktoplevel() combo <- tkwidget(tt,"iwidgets::combobox") tkpack(combo) ### AND THIS WORKS TOO !!! ### tt<-tktoplevel() win <- .Tk.subwin(tt)

Hello, I am exploring the TCLTK package under R and try to load and use additional TCL libraries (under Windows, with TCL8.3). For example : > addTclPath("C:/TCL/lib/bwidget1.5") > tclRequire("BWidget") <Tcl> 1.5 Loading seems to work, but when I try to create a specific widget : # The main window appears correctly > top=tktoplevel() # Trying to insert a

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

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

All: The select.list() command brings up a "modal dialog box with a (scrollable) list of items ..." etc. -- i.e., a GUI control. I also know about winDialog, file.choose and the winMenu commands. What other such GUIisms are built into ** base ** R (I know about the tcltk package)? Or, better yet, how can I search on or list them? Many thanks. Bert Gunter Biometrics Research RY 84-16

I would like to use a tclArray: mytkarray <- tclArray() as the variable for a table: table1 <- tkwidget(f1, 'table', variable= mytkarray) but if I include character strings with embedded spaces, I get braces appearing in the table. I can remove them using a non-R tclarray, (the difference between the first example of http://www.sciviews.org/_rgui/tcltk/Tktable.html and

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,

The following gives an error message: library(tcltk) win <- list(env="A") tt <- tktoplevel() but <- tkbutton(tt, text="X", command=expression(tkdestroy(tt))) tkgrid(but) however, if one comments out the win line (and removes the win variable) then it works. It seems that tcltk is making use of a variable called win with a component name of env and I just happened
