-where the border may be (wxTOP, wxBOTTOM, wxLEFT, wxRIGHT or wxALL). The other
-flags determine the child window's behaviour if the size of the sizer changes.
-However this is not - in contrast to the {\it option} flag - in the main
-orientation, but in the respectively other orientation. So 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 either wxGROW or wxEXPAND), it may get proportionally
-resized (wxSHAPED), it may get centered (wxALIGN\_CENTER or wxALIGN\_CENTRE)
-or it may get aligned to either side (wxALIGN\_LEFT and wxALIGN\_TOP are set
-to 0 and thus represent the default, wxALIGN\_RIGHT and wxALIGN\_BOTTOM have

-in the main orientation using wxALIGN\_CENTER\_VERTICAL (same as
-wxALIGN\_CENTRE\_VERTICAL) and wxALIGN\_CENTER\_HORIZONTAL (same as
