tk mouse cursor icon widget tkwinfo tkfocus questions
...ildren $window] {
$widget config -cursor watch
}
To do this I'll need a list of R/tcl widget objects:
lapply(widglist, function(z) tkconfigure(z, cursor="watch"))
From where can I get this widglist?
I tried:
> tkwinfo("children",topwindow)
<Tcl> .1.1 .1.2 .1.3
I'm guessing this is a string directly returned from tcl.
Is there a way to turn this into a list of widgets after some parsing?
Right now I'm using a hardcoded list for widglist, but if I or others
change...

tk non-widget commands (esp. update and winfo)
...you!
Alas, I also have questions: In Tcl everything is a string [*]. This
is not the case in R, of course. So why are return values of tk
commands still strings? (Is there any other reason than speed or
"package is work in progress"?)
Example:
> tt <- tktoplevel ()
> tkwinfo ("width", tt)
[1] "200"
Could (Should?) be:
> tt <- tktoplevel ()
> tkwinfo ("width", tt)
[1] 200
with
> tkwidth <- function (widget) as.numeric (tkcmd ("winfo", "width", widget))
Maybe a better example is the use of...

Getting width of Tk text widget via tcltk

latter directly.
Any help...

Problem with geometry manager in TclTK
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') and this function is
called by another function ('inputDialog', as follows), I always get the
value '1' for width and height.
Provided below is...
