Member Function Documentation

const char * QString::ascii () const

Use toAscii() instead.

Warning: This function is not reentrant.

See also setAscii().

QChar QString::constref ( uint i ) const

Use at() instead.

bool QString::contains ( QChar c, bool cs ) const

Use the contains(QChar, Qt::CaseSensitive) overload instead.

bool QString::contains ( const QString & s, bool cs ) const

Use the contains(QString, Qt::CaseSensitive) overload instead.

QString QString::copy () const

Use simple assignment instead. QString is implicitly shared so if a copy is modified only the copy is changed.

bool QString::endsWith ( const QString & s, bool cs ) const

Use the endsWith(QString, Qt::CaseSensitive) overload instead.

int QString::find ( QChar c, int i = 0, bool cs = true ) const

Use indexOf() instead.

int QString::find ( const QString & s, int i = 0, bool cs = true ) const

Use indexOf() instead.

int QString::find ( const QRegExp & rx, int i = 0 ) const

Use indexOf() instead.

int QString::findRev ( QChar c, int i = -1, bool cs = true ) const

Use lastIndexOf() instead.

int QString::findRev ( const QString & s, int i = -1, bool cs = true ) const

Use lastIndexOf() instead.

int QString::findRev ( const QRegExp & rx, int i = -1 ) const

Use lastIndexOf() instead.

QString QString::fromUcs2 ( const ushort * unicode, int size = -1 )   [static]

Use fromUtf16() instead.

const char * QString::latin1 () const

Use toLatin1() instead.

Warning: This function is not reentrant.

See also setLatin1().

QString QString::leftJustify ( int width, QChar fill = QLatin1Char( ' ' ), bool trunc = false ) const

Use leftJustified() instead.

QByteArray QString::local8Bit () const

Use toLocal8Bit() instead.

Warning: This function is not reentrant.

QString QString::lower () const

Use toLower() instead.

QChar & QString::ref ( uint i )

Use operator[]() instead.

QString & QString::remove ( QChar c, bool cs )

Use the remove(QChar, Qt::CaseSensitive) overload instead.

QString & QString::remove ( const QString & s, bool cs )

Use the remove(QString, Qt::CaseSensitive) overload instead.

QString & QString::replace ( QChar c, const QString & after, bool cs )

Use the replace(QChar, QString, Qt::CaseSensitive) overload instead.

QString & QString::replace ( const QString & before, const QString & after, bool cs )

Use the replace(QString, QString, Qt::CaseSensitive) overload instead.

QString & QString::replace ( char c, const QString & after, bool cs )

Use the replace(QChar, QString, Qt::CaseSensitive) overload instead.

QString QString::rightJustify ( int width, QChar fill = QLatin1Char( ' ' ), bool trunc = false ) const

Use rightJustified() instead.

QString & QString::setAscii ( const char * str, int len = -1 )
