[Xotcl] Fwd: Re: namespace in constructor referring an instvar?

[Gustaf Neumann]

Dear Tuyen,

Most likely, you want something like the following (see below). Adding
additional namespaces makes things more complicated. Creating procs from
a constructor is as well a rather unusual construction, normally you
want to define methods accessing the instance variables...

best regards

===================
Class  create MatlabInterface -parameter {iss}
MatlabInterface instproc ok {} {
   my instvar iss
   tk_messageBox -type ok -icon info -title "MicWatch" -message $iss
}

MatlabInterface i1 -iss Hello?
i1 ok
===================
