Qt 3 Support Members for QByteArray

The 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 member function, provided for convenience.

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.
