wxSizer is the abstract base class used for laying out subwindows in a window. You

\helpref{wxStaticBoxSizer}{wxstaticboxsizer} or \helpref{wxNotebookSizer}{wxnotebooksizer}.
The layout algorithm used by sizers in wxWindows is closely related to layout
reports its own minimal size and the algorithm can handle differences in font sizes
or different window (dialog item) sizes on different platforms without problems. If e.g.
the standard font as well as the overall design of Motif widgets requires more space than

have no meaning in the wxSizer class itself, but as there currently is only one class
deriving directly from wxSizer and this class does not override these methods, the meaning

value of 1 each to make them grow and shrink equally with the sizer's horizontal dimension.}
\docparam{flag}{This parameter can be used to set a number of flags which can be combined using

around a window: the {\it border} parameter determines the border width whereas the flags given here

if you created a wxBoxSizer with the wxVERTICAL option, these flags will be relevant if the
sizer changes its horizontal size. A child may get resized to completely fill out the new size (using

and thus represent the default, wxALIGN\_RIGHT and wxALIGN\_BOTTOM have their obvious meaning).
With proportional resize, a child may also be centered in the main orientation using
wxALIGN\_CENTER\_VERTICAL (same as wxALIGN\_CENTRE\_VERTICAL) and wxALIGN\_CENTER\_HORIZONTAL
