based upon the idea of the individual subwindows reporting their minimal required
size and their ability to get stretched if the size of the parent window has changed.
This will most often mean, that the programmer does not set the original size of

+the dialog in the beginning, rather the top-most sizer will get queried and it will
then query its children. Its children can be normal windows or other sizers, so that
a hierachy of sizer can be constructed. Note that sizer are not derived from wxWindows
and thus do not interfere with tab ordering and require very little resources compared
the standard font as well as the overall design of Motif widgets requires more space than
on Windows, the intial dialog size will automatically be bigger on Motif than on Windows.

+derive the class from \tt{wxPySizer} in order to get Python-aware
+capabilities for the various virtual methods.}

Adds the {\it window} to the sizer. As wxSizer itself is an abstract class, the parameters
have no meaning in the wxSizer class itself, but as there currently is only one class
to indicate if a child of a sizer can change its size in the main orientation of the wxBoxSizer - where
0 stands for not changable and a value of more than zero in interpreted relative to the value of other
children of the same wxBoxSizer. You might, e.g., have a horizontal wxBoxSizer with three children, two

\docparam{flag}{This parameter can be used to set a number of flags which can be combined using
the binary OR operator |. Two main behaviours are defined using these flags: One is the border
sizer changes its horizontal size. A child may get resized to completely fill out the new size (using
either wxGROW or wxEXPAND), may get centered (wxCENTER or wxCENTRE) or may get aligned to either
side (wxALIGN\_LEFT and wxALIGN\_TOP are set to 0 and thus represent the default, wxALIGN\_RIGHT and

+Tell the sizer to set the minimal size of the {\it window} to match the sizer's minimal size.
This is commonly done in the constructor of the window itself, see sample in the description
of \helpref{wxBoxSizer}{wxboxsizer} if the window is resizable (as many dialogs under Unix and
frames on probably all platforms).
