## Member Function Documentation

### QRegExp::QRegExp ( const QString & pattern, bool cs, bool wildcard = false )

Use another constructor instead.

For example, if you have code like

     QRegExp rx("*.txt", false, true);

you can rewrite it as

     QRegExp rx("*.txt", Qt::CaseInsensitive, QRegExp::Wildcard);

### bool QRegExp::caseSensitive () const

Use caseSensitivity() instead.

See also setCaseSensitive().

### bool QRegExp::minimal () const

Use isMinimal() instead.

See also setMinimal().

### int QRegExp::numCaptures () const

Returns the number of captures contained in the regular expression.

See also captureCount().

### int QRegExp::search ( const QString & str, int from = 0, CaretMode caretMode = CaretAtZero ) const

Use indexIn() instead.

### int QRegExp::searchRev ( const QString & str, int from = -1, CaretMode caretMode = CaretAtZero ) const

Use lastIndexIn() instead.

### void QRegExp::setCaseSensitive ( bool sensitive )

Use setCaseSensitivity() instead.

See also caseSensitive().

### void QRegExp::setWildcard ( bool wildcard )

Use setPatternSyntax() instead.

For example, if you have code like

     rx.setWildcard(wc);

you can rewrite it as

     rx.setPatternSyntax(wc ? QRegExp::Wildcard : QRegExp::RegExp);

See also wildcard().

### bool QRegExp::wildcard () const

Use patternSyntax() instead.

For example, if you have code like

     bool wc = rx.wildcard();

you can rewrite it as

     bool wc = (rx.patternSyntax() == QRegExp::Wildcard);

See also setWildcard().
