Detailed Description
This class is defined in the Qt NSPlugin Extension, which can be found in the qt/extensions directory. It is not included in the main Qt API.
The QNPStream class provides a stream of data provided to a QNPInstance by the browser.
Note that this is neither a QTextStream nor a QDataStream.
See also QNPInstance::write() and QNPInstance::newStreamCreated().
Member Function Documentation
QNPStream::QNPStream ( QNPInstance * in, const char * mt, _NPStream * st, bool se )
Creates a stream. Plugins should not call this, but rather QNPInstance::newStream() if a stream is required.Takes a QNPInstance in, mime type mt, a pointer to an _NPStream st and a seekable flag se.
QNPStream::~QNPStream ()
Destroys the stream.bool QNPStream::complete () const
Returns TRUE if the stream has received all the data from the source; otherwise returns FALSE.uint QNPStream::end () const
Returns the length of the stream in bytes. Can be 0 for streams of unknown length.QNPInstance * QNPStream::instance ()
Returns the QNPInstance for which this stream was created.
uint QNPStream::lastModified () const
Returns the time when the source of the stream was last modified.bool QNPStream::okay () const
Returns TRUE if no errors have occurred on the stream; otherwise returns FALSE.void QNPStream::requestRead ( int offset, uint length )
Requests the section of the stream, of length bytes from offset, be sent to the QNPInstance::write() function of the instance() of this stream.bool QNPStream::seekable () const
Returns TRUE if the stream is seekable; otherwise returns FALSE.const char * QNPStream::type () const
Returns the MIME type of the stream.const char * QNPStream::url () const
Returns the URL from which the stream was created.int QNPStream::write ( int len, void * buffer )
Writes len bytes from buffer to the stream.This file is part of the Qt toolkit. Copyright © 1995-2002 Trolltech. All Rights Reserved.
