QString fontString = "Arial,10,-1,false"; QFont newFont = QFont::fromString(fontString);
QString fontString = "Comic Sans MS,12,75,true"; QFont newFont = QFont::fromString(fontString);In this example, a font string is created using the font name "Comic Sans MS", a point size of 12, a weight of 75 (which means bold), and true for italic. Then, a new QFont object is created using the fromString function. Both examples demonstrate how you can use QFont fromString to generate a valid QFont object from a font string. The package library for QFont fromString is Qt, which is a cross-platform application framework developed by The Qt Company.
