Re: [Boa Constr] sizers problem

[<fcc...@fi...>]

Hi werner,,


I was curious about one thing. In the Book WxPython in action, in the examp=
les=20
the position of the widgets is not set, which makes sense, since the sizers=
=20
should control the positions of the widgets. In Boa the positions of the=20
widgets remain in the code. (which stick to their specified positions).

Another difference that I notice is that the example in the book call the=20
method fit on the main sizer:

mainSizer.Fit(self) #self is the frame

This is also something that boa does not do.

Do you think this may be the problem/
