\section{\class{wxSize}}\label{wxsize}

A {\bf wxSize} is a useful data structure for graphics operations.
It simply contains integer {\it width} and {\it height} members.

wxSize is used throughout wxWidgets as well as wxPoint which, although almost
equivalent to wxSize, has a different meaning: wxPoint represents a position
while wxSize - the size.

\pythonnote{wxPython defines aliases for the {\tt x} and {\tt y} members
named {\tt width} and {\tt height} since it makes much more sense for
sizes.

\membersection{wxSize::wxSize}\label{wxsizector}

\func{}{wxSize}{\void}

\func{}{wxSize}{\param{int}{ width}, \param{int}{ height}}

Creates a size object.



\membersection{wxSize::DecTo}\label{wxsizedecto}

\func{void}{DecTo}{\param{const wxSize\& }{size}}

Decrements this object so that both of its dimensions are not greater than the
corresponding dimensions of the \arg{size}.

\helpref{IncTo}{wxsizeincto}


\membersection{wxSize::IsFullySpecified}\label{wxsizeisfullyspecified}

\constfunc{bool}{IsFullySpecified}{\void}

Returns \true if neither of the size object components is equal to $-1$, which
is used as default for the size values in wxWidgets (hence the predefined 
\texttt{wxDefaultSize} has both of its components equal to $-1$).

This method is typically used before calling 
\helpref{SetDefaults}{wxsizesetdefaults}.


\membersection{wxSize::GetWidth}\label{wxsizegetwidth}

\constfunc{int}{GetWidth}{\void}

Gets the width member.


\membersection{wxSize::GetHeight}\label{wxsizegetheight}

\constfunc{int}{GetHeight}{\void}

Gets the height member.



\membersection{wxSize::IncTo}\label{wxsizeincto}

\func{void}{IncTo}{\param{const wxSize\& }{size}}

Increments this object so that both of its dimensions are not less than the
corresponding dimensions of the \arg{size}.

\helpref{DecTo}{wxsizedecto}



\membersection{wxSize::Set}\label{wxsizeset}

\func{void}{Set}{\param{int}{ width}, \param{int}{ height}}

Sets the width and height members.


\membersection{wxSize::SetDefaults}\label{wxsizesetdefaults}

\func{void}{SetDefaults}{\param{const wxSize\& }{sizeDefault}}

Combine this size object with another one replacing the default (i.e. equal
to $-1$) components of this object with those of the other. It is typically
used like this:
\begin{verbatim}
    if ( !size.IsFullySpecified() )
    {
        size.SetDefaults(GetDefaultSize());
    }
\end{verbatim}

\membersection{wxSize::SetHeight}\label{wxsizesetheight}

\func{void}{SetHeight}{\param{int}{ height}}

Sets the height.


\membersection{wxSize::SetWidth}\label{wxsizesetwidth}

\func{void}{SetWidth}{\param{int}{ width}}

Sets the width.


\membersection{wxSize::operator $=$}\label{wxsizeassign}

\func{void}{operator $=$}{\param{const wxSize\& }{sz}}

Assignment operator.
