◆ familySupportsWritingSystem()

bool familySupportsWritingSystem ( QtFontFamily * family,
size_t writingSystem )
static

Tests if the given family family supports writing system writingSystem, including the special case for Han script mapping to several subsequent writing systems

static

Definition at line 1057 of file qfontdatabase.cpp.

◆ parseFontName()

void parseFontName ( const QString & name,
QString & foundry,
QString & family )
static

This makes sense of the font family name:

if the family name contains a '[' and a ']', then we take the text between the square brackets as the foundry, and the text before the square brackets as the family (ie. "Arial [Monotype]")
