Help with TCL packages
Thanks for your reply Peter.
I haven't got BWidgets around, but it seems that it likes to use MacCapitalizationStyle, so shouldn't it be BWidget::ComboBox ??
I have tried many case variations, but none worked.
In general, you might want to try things out in the "wish" interpreter since R interfaces to an embedded Tcl interpreter and you're seeing its error messages.
What TCL command would you suggest (I am no expert in TCL)? I also tried to load IWidgets, but now, loading doesn't work !
library(tcltk)
addTclPath("C:/TCL/LIB/IWIDGETS4.0.2")
tclRequire("IWidgets")
Error in structure(.External("dotTcl", ..., PACKAGE = "tcltk"), class = "tclObj") :
[tcl] can't find package IWidgets.
again when varying lower/upper case.
I would like to use one of these to write a simple TCLTK interface to R for my students.

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 combobox
combo <- tkwidget(top,"BWidget::combobox")
Error in structure(.External("dotTcl", ..., PACKAGE = "tcltk"), class = "tclObj") :
[tcl] invalid command name "BWidget::combobox".
The file combobox.tcl is present in the BWidget directory.
I wonder what I'm doing wrong. Any idea ?
