In my vision, in tcl/tk world there is only one mainwindow (a toplevel with
path '.'), but this is per interpreter.
With tk-enabled Tcl.pm you could do
my $interp2 = $interp1->interp('create');
and have another mainwindow for $interp2.
As it seems to me, the Tkx package creates only one tcl interpreter within
Tkx::i package and does not expose it to the user. So it seems to me that
seconf interpreter is not possible for Tkx, but could be possible with a minor
modifications to Tkx.
On the contrary, in Tcl::Tk any widget has "interp" method, which gives you an
instance to widget's interpreter, so it is possible to create another one, but
I never used that feature, may be it is never needed...
Which makes me wonder - is my understanding true, that in Tkx a user is not
allowed to do tcl/tk's evals?
IMO, this is a really nice feature! Really powerful!
