Re: Threads and main-loops

[Matt Jarjoura <jarjoura gmail com>]

Can you just convert what you need into signals?  Then you can store
each of your document windows into a GList (or a STL vector) and
manage your documents that way.  When each of the signals is fired the
current document can handle the event.

Is there a reason you need a seperate thread per document?  Personally
I would just keep one thread dedicated to the UI.  Then whatever
requires seperate threading can be done in a signal call and close up
when finished.
