1 \section{\class{wxPrivateDataObject}}\label{wxprivatedataobject}
2
3 wxPrivateDataObject is a specialization of wxDataObject for application-specific or standard
4 format data. The format of the data contained in an instance of this class must be identified
5 with a string literal corresponding to the mime-type of the data. Typically this would be
6 "image/png" or "text/html" or "application/word".

29
30 The string ID identifies the format of clipboard or DnD data. A word
31 processor would e.g. add a wxTextDataObject and a wxPrivateDataObject
32 to the clipboard - the latter with the Id "application/word".

34 \membersection{wxPrivateDataObject::GetId}\label{wxprivatedataobjectgetid}
35
36 \constfunc{virtual wxString}{GetId}{\void}
37
38 Returns the ID of the clipboard or DnD data format.

42 \func{virtual void}{SetData}{\param{const char }{*data}, \param{size\_t }{size}}
43
44 Set the data. The data object will make an internal copy.

47
48 \constfunc{virtual size\_t}{GetDataSize}{\void}

50 Returns the data size.

53
54 \func{virtual char*}{GetData}{\void}
55
56 Returns a pointer to the data.

58 \membersection{wxPrivateDataObject::WriteData}\label{wxprivatedataobjectwritedata}
59
60 \constfunc{virtual void}{WriteData}{\param{void}{*dest} }
61
62 Write the data owned by this class to {\it dest}. By default, this
63 calls \helpref{WriteData}{wxprivatedataobjectwritedata2} with data
64 set using \helpref{SetData}{wxprivatedataobjectsetdata}.
65 This can be overridden to provide data on-demand; in this case
66 \helpref{WriteData(data,dest)}{wxprivatedataobjectwritedata2} (see below) must be called from
67 within the overriding WriteData() method.

69 \membersection{wxPrivateDataObject::WriteData}\label{wxprivatedataobjectwritedata2}
70
71 \constfunc{void}{WriteData}{\param{const char* }{data}, \param{void}{*dest} }
72
73 Writes the data {\it data} to {\it dest}. This method must be called
74 from \helpref{WriteData}{wxprivatedataobjectwritedata}.
