## Member Function Documentation

### bool QFontDatabase::bold ( const QString & family, const QString & style, const QString & charSet ) const

This is an overloaded member function, provided for convenience. It behaves essentially like the above function.

The charSet parameter has been deprecated since Qt 3.0. The character set can be queried using QFont::charSet().

Use the other bold() function instead.

### QStringList QFontDatabase::families ( bool onlyForLocale ) const

This is an overloaded member function, provided for convenience. It behaves essentially like the above function.

The onlyForLocale parameter has been deprecated since Qt 3.0.

Use the other families() function instead.

### QFont QFontDatabase::font ( const QString & familyName, const QString & style, int pointSize, const QString & charSet )

This is an overloaded member function, provided for convenience. It behaves essentially like the above function.

The charSet parameter has been deprecated since Qt 3.0. The character set can be queried using QFont::charSet().

Use the other font() function instead.

### bool QFontDatabase::isBitmapScalable ( const QString & family, const QString & style, const QString & charSet ) const

This is an overloaded member function, provided for convenience. It behaves essentially like the above function.

The charSet parameter has been deprecated since Qt 3.0. The character set can be queried using QFont::charSet().

Use the other isBitmapScalable() function instead.

### bool QFontDatabase::isFixedPitch ( const QString & family, const QString & style, const QString & charSet ) const

This is an overloaded member function, provided for convenience. It behaves essentially like the above function.

The charSet parameter has been deprecated since Qt 3.0. The character set can be queried using QFont::charSet().

Use the other isFixedPitch() function instead.

### bool QFontDatabase::isScalable ( const QString & family, const QString & style, const QString & charSet ) const

This is an overloaded member function, provided for convenience. It behaves essentially like the above function.

The charSet parameter has been deprecated since Qt 3.0. The character set can be queried using QFont::charSet().

Use the other isScalable() function instead.

### bool QFontDatabase::isSmoothlyScalable ( const QString & family, const QString & style, const QString & charSet ) const

This is an overloaded member function, provided for convenience. It behaves essentially like the above function.

The charSet parameter has been deprecated since Qt 3.0. The character set can be queried using QFont::charSet().

Use the other isSmoothlyScalable() function instead.

This is an overloaded member function, provided for convenience. It behaves essentially like the above function.

The charSet parameter has been deprecated since Qt 3.0. The character set can be queried using QFont::charSet().

Use the other italic() function instead.

### QList<int> QFontDatabase::pointSizes ( const QString & family, const QString & style, const QString & charSet )

This is an overloaded member function, provided for convenience. It behaves essentially like the above function.

The charSet parameter has been deprecated since Qt 3.0. The character set can be queried using QFont::charSet().

Use the other pointSizes() function instead.
