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?

...hould be highlited. Doing this, the event is one timestep behind. For example selecting first element in A, no slection in B becaus eof the error mentioned above. Then selecting the second item in A , the first of B is highlited.

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...

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,

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,...)) levels.list2.scroll<-tkscrollbar(tt,repeatinterval=5,command=function(...)tkyview(levels.list2,...)) tkgrid(levels.list2,levels.list2.scroll) vec<-c("a","b",""," &quot...

Hi, I have two questions: First, does anyone know how to put a combobox inside a GUI made with Tcl/Tk ? I think there isn't a simple way to do this (a command like tkcombobox()!), but is it possible to write a more complex code to achieve this ? Second, when I put two listboxes in the same window or frame (even in two different toplevel windows), I cannot select things in the two lists

...perienced 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", selectmode="single") for (x in letters[1:10]) tkinsert(listbox, "end", x) value <- tclVar("") entry <- tkentry(top, width="2", textvariable=value) onOK <- function(){ tkdestroy(top) print(tclvalue(value)) return()...
