Re: Added MDI support to Pythoncard (was MDI - childwindows within a window)

Python card is great.

But I  caution people stating out on large computationally or database
intensive projects that while pythoncard makes the easy stuff very
easy, it makes that hard stuff harder.  Note that even using wxPython
getting the process-based and thread-based multitasking working
properly can be hard and is essential in any program that uses the
cpu, disk and network intensively and still needs wx to be responsive,
draw progress bars, etc.

I'm warning about big data here (for a GUI anyway): trees with
1000's-10,000's of nodes, grid data stores with ~1M cells.

I've written some cool programs in python card, but they never scaled well.
