\section{\class{wxWrapSizer}}\label{wxwrapsizer}

A wrap sizer lays out its items in a single line, like a box sizer -- as long 
as there is space available in that direction. Once all available space in 
the primary direction has been used, a new line is added and items are added
there.

So a wrap sizer has a primary orientation for adding items, and adds lines
as needed in the secondary direction.

\membersection{wxWrapSizer::wxWrapSizer}\label{wxwrapsizerwxwrapsizer}

\func{}{wxWrapSizer}{\param{int }{orient}, \param{int }{flags}}

Constructor for a wxWrapSizer. \arg{orient} determines the primary direction of
the sizer (the most common case being \texttt{wxHORIZONTAL}). The flags
parameter may have the value \texttt{wxEXTEND\_LAST\_ON\_EACH\_LINE} which will
cause the last item on each line to use any remaining space on that line.


\membersection{wxWrapSizer::InformFirstDirection}\label{wxwrapsizerinformfirstdirection}

\func{bool}{InformFirstDirection}{\param{int }{direction}, \param{int }{size}, 
\param{int }{availableOtherDir }}

Not used by an application. This is the mechanism by which sizers can inform 
sub-items of the first determined size component. The sub-item can then better
determine its size requirements. 

Returns true if the information was used (and the sub-item min size was updated).
