So you don't use all possible options. There is an
sl_label flag or such.

No, I don't. Please try the attachment :-)

I didn't mean to offend you.
Speed isn't the only issue. You can see only one
of the pages. And it is also namespaces.
I'm writing a wizard with some 20 pages. Putting this
all into the same tabbed subwindow gives me headaches
with the myriad of objects, which all appear in the
main frame. By the reparent trick, I can have simple,
small pages, clean distinction between namespaces,
and every page has its own frame for testing.
Furthermore, I can create multiple instances of
them, for pages which do repeat, and so on.

I let them all inherit form a WizPage class mixin,
so they have a defined interface for data transfer,
methods like onSirstShow, onGoNext, onCancel...,
which they can override. There is a central wizard
manager which calls these methods, and also provides
a channel object, where pages can send commands to
change the layout of their environment...
Well, this has quite evolved, and I think to isolate
some framework for others to use, later.

Sure.

Yes, that's fine. Tab selection isn't that slow,
but finding controls and relevant code in the .py
is slow, compared to quite tab access to multiple
modules by the editor :-)

Ahem, yes :)

That would be a break-through. Designing widgets
in the designer. I do this with frames, too, and
when I'm done with it, I move the code into some
class, rename all the self.Panel alikes to self
and make it stand-alone.

I'm doing some ownerdraw stuff, also I do it from
a tasklet in the background, timer controlled.
I found out what happens, it was my fault.
No proper cleanup, the process ended with some
tasklets not finished.

Stackless' parallelism would make sense in Boa.
You could do lots of things in the background,
in a very simple manner. I will give you
an example, later.
