For most purposes QFont is a more appropriate class. + + Most commonly, when presenting text in a user interface, the exact fonts used + to render the characters is to some extent unknown. This can be the case for several + reasons: For instance, the actual, physical fonts present on the target system could be + unexpected to the developers, or the text could contain user selected styles, sizes or + writing systems that are not supported by font chosen in the code. + + Therefore, Qt's QFont class really represents a query for fonts. When text is interpreted, + Qt will do its best to match the text to the query, but depending on the support, different + fonts can be used behind the scenes. + + For most use cases, this is both expected and necessary, as it minimizes the possibility of + text in the user interface being undisplayable. In some cases, however, more direct control + over the process might be useful. It is for these use cases the QRawFont class exists. + + A QRawFont object represents a single, physical instance of a given font in a given pixel size. + I.e. in the typical case it represents a set of TrueType or OpenType font tables and uses a + user specified pixel size to convert metrics into logical pixel units. In can be used in + combination with the QGlyphs class to draw specific glyph indexes at specific positions, and + also have accessors to some relevant data in the physical font. + + QRawFont only provides support for the main font technologies: GDI and DirectWrite on Windows + platforms, FreeType on Symbian and Linux platforms and CoreText on Mac OS X. For other + font back-ends, the APIs will be disabled. + + QRawFont can be constructed in a number of ways: + \list + \o \l It can be constructed by calling QTextLayout::glyphs() or QTextFragment::glyphs(). The + returned QGlyphs objects will contain QRawFont objects which represent the actual fonts + used to render each portion of the text. + \o \l It can be constructed by passing a QFont object to QRawFont::fromFont(). The function + will return a QRawFont object representing the font that will be selected as response to + the QFont query and the selected writing system. + \o \l It can be constructed by passing a file name or QByteArray directly to the QRawFont + constructor, or by calling loadFromFile() or loadFromData(). In this case, the + font will not be registered in QFontDatabase, and it will not be available as part of + regular font selection. + \endlist + + QRawFont is considered local to the thread in which it is constructed (either using a + constructor, or by calling loadFromData() or loadFromFile()).
