The win32ui framework really should not allow a view to be created
without a valid document.
Actually, the problem is that it *won't* allow a view to be
created without a document, even though it should. If I remember
correctly, at the MFC level, the constructor for the view object
I'm using doesn't even take a Document as an argument -- you set
it later if you want one. Win32ui goes out of its way to accept
one at construction time.
This wouldn't be such a serious problem, except that win32ui
doesn't seem to provide any way of creating a Document without
a resource -- hence the above kludge.
The PyGUI framework can probably create a valid MFC document to use
as a dummy with a little work.
Something like:
dt=win32ui.CreateDocTemplate(win32ui.IDR_PYTHONTYPE)
win_dummy_doc=dt.DoCreateDoc()
That may work if you run the program using the pythonwin
executable, which contains the referenced resource. But I want
pygui programs to be runnable using the standard Python
interpreter, which means I can't rely on resources at all.
There are two ways that pywin32 could be modified to fix this
problem:
1) Allow a View to be created without a Document (preferable).
2) Provide a way of creating a Document without requiring a
resource (e.g. from a string template).
