Appends a child to the sizer.
wxSizer itself is an abstract class, but the parameters are
equivalent in the derived classes that you will instantiate to
use it so they are described here:
Parameters:
window The window to be added to the sizer. Its initial size
(either set explicitly by the user or calculated internally when
using wxDefaultSize) is interpreted as the minimal and in many
cases also the initial size.
proportion Although the meaning of this parameter is
undefined in wxSizer, it is used in wxBoxSizer to indicate if a
child of a sizer can change its size in the main orientation of
the wxBoxSizer - where 0 stands for not changeable and a value
of more than zero is interpreted relative to the value of other
children of the same wxBoxSizer. For example, you might have a
horizontal wxBoxSizer with three children, two of which are
supposed to change their size with the sizer. Then the two
stretchable windows would get a value of 1 each to make them
grow and shrink equally with the sizers horizontal dimension.
flag OR-combination of flags affecting sizers behaviour.
See wxSizer flags list for details.
border Determines the border width, if the flag parameter is
set to include any border flag.
userData Allows an extra object to be attached to the
sizer item, for use in derived classes when sizing information
is more complex than the proportion and flag will allow for.
