The TQMimeSource class is an abstraction of objects which provide formatted data of a certain MIME type.
< p >
< p > < a href = "dnd.html" > Drag-and-drop< / a > and
< a href = "ntqclipboard.html" > clipboard< / a > use this abstraction.
< p > < p > See also < a href = "http://www.isi.edu/in-notes/iana/assignments/media-types/
">IANA list of MIME media types< / a > , < a href = "draganddrop.html" > Drag And Drop Classes< / a > , < a href = "io.html" > Input/Output and Networking< / a > , and < a href = "misc.html" > Miscellaneous Classes< / a > .
< hr > < h2 > Member Function Documentation< / h2 >
< h3 class = fn > < a name = "TQMimeSource" > < / a > TQMimeSource::TQMimeSource ()
< / h3 >
Constructs a mime source and assigns a globally unique serial
number to it.
< p > < p > See also < a href = "#serialNumber" > serialNumber< / a > ().
< h3 class = fn > < a name = "~TQMimeSource" > < / a > TQMimeSource::~TQMimeSource ()< tt > [virtual]< / tt >
< / h3 >
Provided to ensure that subclasses destroy themselves correctly.
< h3 class = fn > < a href = "qbytearray.html" > TQByteArray< / a > < a name = "encodedData" > < / a > TQMimeSource::encodedData ( const char * ) const< tt > [pure virtual]< / tt >
< / h3 >
< p > Returns the encoded data of this object in the specified MIME
format.
< p > Subclasses must reimplement this function.
< p > Reimplemented in < a href = "qstoreddrag.html#encodedData" > TQStoredDrag< / a > , < a href = "qdropevent.html#encodedData" > TQDropEvent< / a > , and < a href = "qicondrag.html#encodedData" > TQIconDrag< / a > .
< h3 class = fn > const char * < a name = "format" > < / a > TQMimeSource::format ( int i = 0 ) const< tt > [pure virtual]< / tt >
< / h3 >
< p > Returns the < em > i< / em > -th supported MIME format, or 0.
< p > Reimplemented in < a href = "qdropevent.html#format" > TQDropEvent< / a > .
< h3 class = fn > bool < a name = "provides" > < / a > TQMimeSource::provides ( const char * mimeType ) const< tt > [virtual]< / tt >
< / h3 >
Returns TRUE if the object can provide the data in format < em > mimeType< / em > ; otherwise returns FALSE.
< p > If you inherit from TQMimeSource, for consistency reasons it is
better to implement the more abstract canDecode() functions such
as < a href = "qtextdrag.html#canDecode" > TQTextDrag::canDecode< / a > () and < a href = "qimagedrag.html#canDecode" > TQImageDrag::canDecode< / a > ().
< p > Example: < a href = "simple_dd-example.html#x2825" > iconview/simple_dd/main.cpp< / a > .
< p > Reimplemented in < a href = "qdropevent.html#provides" > TQDropEvent< / a > .
< h3 class = fn > int < a name = "serialNumber" > < / a > TQMimeSource::serialNumber () const
< / h3 >
< p > Returns the mime source's globally unique serial number.
