Composite Widget How-To?

From: Mark Elston <els...@cave.arc.nasa.gov>

I have been trying to put together a composite widget (a somewhat
modified version of the FileSelect widget that came with Tk-b8).
After looking at the code that exists I began to wonder just where to
start.  I found that the documentation that we have so far really does
not explain a lot of the inner workings of Composites very well.  At
least not if you are just trying to come up to speed on them (like
me).

I have read the Composite.pod and ConfigSpec.pod entries and looked at
Frame.pm and demo/LabEnLabRad.pm and I must admit that I am still
lost.

For example, what does the 'Component' method do?  How about
'Advertise'?  I still can't make out how 'Delegates' is used even
after reading the (cryptic) references to it in Composite and looking
at any examples I can find.  Where are these methods documented?  Are
they documented?

ConfigSpecs is better documented but I am still having trouble putting
it into perspective.  Perhaps if I could only understand the rest of
the stuff that goes on in the Populate method ...

Can anyone help get me up over whatever hump(s) I am facing?

Thanks.

Mark.
