\section{\class{wxPrivateDataObject}}\label{wxprivatedataobject}

wxPrivateDataObject is a specialization of wxDataObject for application-specific or standard
format data. The format of the data contained in an instance of this class must be identified
with a string literal corresponding to the mime-type of the data. Typically this would be
"image/png" or "text/html" or "application/word".

\membersection{wxPrivateDataObject::wxPrivateDataObject}\label{wxprivatedataobjectwxprivatedataobject}

\func{}{wxPrivateDataObject}{\void}

\membersection{wxPrivateDataObject::\destruct{wxPrivateDataObject}}\label{wxprivatedataobjectdtor}

\func{}{\destruct{wxPrivateDataObject}}{\void}

\membersection{wxPrivateDataObject::SetId}\label{wxprivatedataobjectsetid}

\func{virtual void}{SetId}{\param{const wxString\& }{id}}

The string ID identifies the format of clipboard or DnD data. A word
processor would e.g. add a wxTextDataObject and a wxPrivateDataObject
to the clipboard - the latter with the Id "application/word".

\membersection{wxPrivateDataObject::GetId}\label{wxprivatedataobjectgetid}

\constfunc{virtual wxString}{GetId}{\void}

Returns the ID of the clipboard or DnD data format.

\membersection{wxPrivateDataObject::SetData}\label{wxprivatedataobjectsetdata}

\func{virtual void}{SetData}{\param{const char }{*data}, \param{size\_t }{size}}

Set the data. The data object will make an internal copy.

\membersection{wxPrivateDataObject::GetSize}\label{wxprivatedataobjectgetsize}

\constfunc{virtual size\_t}{GetDataSize}{\void}

Returns the data size.

\membersection{wxPrivateDataObject::GetData}\label{wxprivatedataobjectgetdata}

\func{virtual char*}{GetData}{\void}

Returns a pointer to the data.

\membersection{wxPrivateDataObject::WriteData}\label{wxprivatedataobjectwritedata}

\constfunc{virtual void}{WriteData}{\param{void}{*dest} }

Write the data owned by this class to {\it dest}. By default, this
calls \helpref{WriteData}{wxprivatedataobjectwritedata2} with data 
set using \helpref{SetData}{wxprivatedataobjectsetdata}.
This can be overridden to provide data on-demand; in this case
\helpref{WriteData(data,dest)}{wxprivatedataobjectwritedata2} (see below) must be called from
within the overriding WriteData() method.

\membersection{wxPrivateDataObject::WriteData}\label{wxprivatedataobjectwritedata2}

\constfunc{void}{WriteData}{\param{const char* }{data}, \param{void}{*dest} }

Writes the data {\it data} to {\it dest}. This method must be called
from \helpref{WriteData}{wxprivatedataobjectwritedata}.
