I don't understand this comment. First, there is a preference for being
prompted for the name of every widget. Below is an example where I
specified toplevel=mytop, frame=myframe, and button=confirmdelete. Isn't
that what they want?
Secondly, I've never used the feature above; I just use the widget alias
feature. Supplying your own names would be handy when being confronted
with stack traces during debugging, I suppose.
proc vTclWindow.mytop {base} {
if {$base == ""} {
set base .mytop
}
if {[winfo exists $base]} {
wm deiconify $base; return
}

Yes, I saw that the other day but haven't downloaded it yet.
Now would be a good time for Stewart to give us an update on his plans for
vTcl development!
