RE: [Boa Constr] calling child windows

Thanks for such a comprehensive reply and your example code. It's really
helped my understanding of MDI parent & child windows. Boa allows the novice
(like me) to contemplate GUI development - the product is truly brilliant!

Thanks again

Finbarr

This is fine.
Remember that if you keep a reference around (e.g. self.child) to this
child window, that you need to clear this reference when the child
closes or accessing this reference will cause a crash.

I've now written an MDI example for Boa based on recent (and past)
requests. Thanks to Robin for his MDI examples.

It uses wxLayoutAlgorithm and a wxSashLayoutWindow, I don't know
of a simpler way to to MDI where you have controls on the parent.
It's much simpler tho to have a splitter and a tree ctrl behave
properly than I suspected in a previous message to the list.

The example is attached, note all the properties that need to be
set for this to work properly.
