Member Type Documentation

typedef QIODevice::Offset

Use qint64 instead.

typedef QIODevice::Status

Use QIODevice::OpenMode instead, or see the documentation for specific devices.


Member Function Documentation

Offset QIODevice::at () const

Use pos() instead.

bool QIODevice::at ( Offset offset )

Use seek(offset) instead.

int QIODevice::flags () const

Use openMode() instead.

int QIODevice::getch ()

Use getChar() instead.

bool QIODevice::isAsynchronous () const

This functionality is no longer available. This function always returns true.

bool QIODevice::isBuffered () const

Use !(openMode() & QIODevice::Unbuffered) instead.

bool QIODevice::isCombinedAccess () const

Use openMode() instead.

bool QIODevice::isDirectAccess () const

Use !isSequential() instead.

bool QIODevice::isInactive () const

Use isOpen(), isReadable(), or isWritable() instead.

bool QIODevice::isRaw () const

Use openMode() instead.

bool QIODevice::isSequentialAccess () const

Use isSequential() instead.

bool QIODevice::isSynchronous () const

This functionality is no longer available. This function always returns false.

bool QIODevice::isTranslated () const

Use openMode() instead.

int QIODevice::mode () const

Use openMode() instead.

int QIODevice::putch ( int ch )

Use putChar(ch) instead.

qint64 QIODevice::readBlock ( char * data, quint64 size )

Use read(data, size) instead.

void QIODevice::resetStatus ()

For device specific error handling, please refer to the individual device documentation.

See also qobject_cast().

int QIODevice::state () const

Use isOpen() instead.

Status QIODevice::status () const

For device specific error handling, please refer to the individual device documentation.

See also qobject_cast().

int QIODevice::ungetch ( int ch )

Use ungetChar(ch) instead.

qint64 QIODevice::writeBlock ( const char * data, quint64 size )

Use write(data, size) instead.

qint64 QIODevice::writeBlock ( const QByteArray & data )

Use write(data) instead.
