\class FontDatabase fontdatabase.h
\brief The FontDatabase class provides information about available fonts.
- Provides information about available fonts.
-
- FontDatabase provides information about the available fonts of the
- underlying window system.
+ Most often you will simply want to query the database for the
+ available font families().
- Most often you will simply want to query the database for all font
- families(), and their respective pointSizes(), styles() and charSets().
+ Use FontDatabase rather than QFontDatabase when you may need access
+ to fonts that are not normally available. For example, if the
+ freetype library and the Qtopia freetype plugin are installed,
+ TrueType fonts will be available to your application. Font renderer
+ plugins have greater resource requirements than system fonts so they
+ should be used only when necessary. You can force the loading of
+ font renderer plugins with loadRenderers().
