Qt 3 Support Members for QByteArrayThe following class members are part of the Qt 3 support layer. They are provided to help you port old code to Qt 4. We advise against using them in new code.

Member Function Documentation
QByteArray::QByteArray ( int size )
Use QByteArray(int, char) instead.
QByteArray & QByteArray::duplicate ( const QByteArray & a )
For example, if you have code like
QByteArray bdata;
bdata.duplicate(original);
you can rewrite it as
QByteArray bdata;
bdata = original;
Note: QByteArray uses implicit sharing so if you modify a copy, only the copy is changed.
QByteArray & QByteArray::duplicate ( const char * a, uint n )
This is an overloaded function.
For example, if you have code like
QByteArray bdata;
bdata.duplicate(ptr, size);
you can rewrite it as
QByteArray bdata;
bdata = QByteArray(ptr, size);
Note: QByteArray uses implicit sharing so if you modify a copy, only the copy is changed.
int QByteArray::find ( char c, int from = 0 ) const
Use indexOf() instead.
int QByteArray::find ( const char * c, int from = 0 ) const
Use indexOf() instead.
int QByteArray::find ( const QByteArray & ba, int from = 0 ) const
Use indexOf() instead.
int QByteArray::find ( const QString & s, int from = 0 ) const
Use indexOf() instead.
int QByteArray::findRev ( char c, int from = -1 ) const
Use lastIndexOf() instead.
int QByteArray::findRev ( const char * c, int from = -1 ) const
Use lastIndexOf() instead.
int QByteArray::findRev ( const QByteArray & ba, int from = -1 ) const
Use lastIndexOf() instead.
int QByteArray::findRev ( const QString & s, int from = -1 ) const
Use lastIndexOf() instead.
QByteArray QByteArray::leftJustify ( uint width, char fill = ' ', bool truncate = false ) const
Use leftJustified() instead.
QByteArray QByteArray::lower () const
Use toLower() instead.
void QByteArray::resetRawData ( const char * data, uint n )
Use clear() instead.
QByteArray QByteArray::rightJustify ( uint width, char fill = ' ', bool truncate = false ) const
Use rightJustified() instead.
QByteArray & QByteArray::setRawData ( const char * a, uint n )
Use fromRawData() instead.
QByteArray QByteArray::simplifyWhiteSpace () const
Use simplified() instead.
QByteArray QByteArray::stripWhiteSpace () const
Use trimmed() instead.
QByteArray QByteArray::upper () const
Use toUpper() instead.
