Hi all,

I am wondering the following:

I have a class A. This class A has a variable named "background".

Then, I have a class B. This class has a method (init) that sets a value
to the variable background:

class create B {
method init {} {
my variable background
set background red
}
}

If I have an object from class A, is there a way to execute the init
method (from a B's object) into the context of the A object?

Why I need this?
I had a set of classes, that implement "items" on a canvas:
http://www.ellogon.org/~petasis/tcl/TkRibbon/images/Ellogon-Ribbon-System-Logs.png
There are two major kinds of "items", a "block" and a "connector" (the
arrows).

Right now, colours are coded inside the code (not a good approach). I am
looking for a way to "theme" these classes, where the values for a set
of variables can be retrieved from a "style" object.

There is the alternative for the "item" object to query the value of
each variable from the style object, but many variables and a few items
(it may be slow).

Any ideas?

George
