FindFallbackFont()

virtual bool FontCacheFactory::FindFallbackFont ( const std::string & language_isocode, class MissingGlyphSearcher * callback ) const

pure virtual

We would like to have a fallback font as the current one doesn't contain all characters we need.

Parameters

language_isocode	The language, e.g. en_GB.
callback	The function to call to check for missing glyphs.

Returns

true if a font has been set, false otherwise.

Implemented in CoreTextFontCacheFactory, FreeTypeFontCacheFactory, SpriteFontCacheFactory, and Win32FontCacheFactory.

LoadFont()

virtual std::unique_ptr< FontCache > FontCacheFactory::LoadFont ( FontSize fs, FontType fonttype, bool search, const std::string & font_name, const std::any & os_handle ) const

pure virtual

Try loading a font with this factory.

Parameters

fs	Font size to load.
fonttype	Font type requested.
search	Set if searching for the font.
font_name	Font name to load.
os_handle	Font handle to load.
