overridevirtual |
This function is called once at startup by Qt's internal font database.
Reimplement this function in a subclass for a convenient place to initialize the internal font database.
You may lazily populate the database by calling registerFontFamily() instead of registerFont(), in which case you'll get a callback to populateFamily() when the required family needs population. You then call registerFont() to finish population of the family.
The default implementation does nothing.
