You can test that the character set is correct using the QFontInfo class. The family name is case insensitive. If the family is not available a default family is used. Sets fixed pitch on or off. A fixed pitch font is a font where all characters have the same width.
Sets italic on or off.
The point size must be greater than zero. Calling this function only has effect under X windows. If raw mode is enabled, Qt will search for an X font with a complete font name matching the family name, ignoring all other values set for the QFont. Sets strike out on or off. The style hint is used by the font matching algorithm when a selected font family cannot be found and is used to find an appropriate default family.
