[Qt-interest] font family insertSubstitutions

[Giacomo]

Hi to all.

Can anyone explain me how QFont::insertSubstitutions works?

I call 

QFont f = font();

QFont::insertSubstitutions("Sans Serif", QStringList() << "Helvetica" << 
"Verdana" << "Monospace");

f->setFamily("Sans Serif");

/* this is not installed, actually is rendered very badly */

qDebug() << f->family();  /* says Sans Serif! */

although Monospace and verdana are installed...

Can someone help?

Thanks in advance

Giacomo
