[R] how to work ttkspinbox ? win BUG ??

[Fox, John]

Dear Cleber,

I can verify this problem on Windows; my session info:

---------- snip --------

> sessionInfo()
R version 3.3.1 (2016-06-21)
Platform: x86_64-w64-mingw32/x64 (64-bit)
Running under: Windows >= 8 x64 (build 9200)

locale:
[1] LC_COLLATE=English_Canada.1252  LC_CTYPE=English_Canada.1252    LC_MONETARY=English_Canada.1252
[4] LC_NUMERIC=C                    LC_TIME=English_Canada.1252    

attached base packages:
[1] tcltk     stats     graphics  grDevices utils     datasets  methods   base     

loaded via a namespace (and not attached):
[1] tools_3.3.1

---------- snip --------

I suspect that ttk::spinbox is missing from the supplied Tcl/Tk (though other ttk widgets are present).

You can use spinbox from Tk by defining your own tkspinbox() function (there isn't one in the tcltk package):

	tkspinbox <- function(parent, ...) tkwidget(parent, "spinbox", ...)

Then, e.g., 

	t <- tktoplevel()
	s <- tkspinbox(t, from = 1.0, to = 100.0, textvariable='spinval')
	tkpack(s)

works for me.

Best,
 John
