#includeIn the first example, we create a `QFont` object with the font family "Times New Roman", a point size of 12, bold weight, and true italics. Then, we call `toString()` to get a string representation of the font properties and print it to the console. In the second example, we create an empty `QFont` object and populate it with font properties by calling `fromString()` with a previously-generated string. Then, we use getters like `family()`, `pointSize()`, `bold()`, and `italic()` to retrieve the specific font characteristics and print them to the console. The `QFont` class is part of the Qt GUI module, which provides high-level user interface components and functionalities for desktop and mobile applications.#include int main() { QFont font("Times New Roman", 12, QFont::Bold, true); qDebug() << font.toString(); // Output: "Times New Roman,12,-1,1,75,0,1,0,0,0,Regular" QFont font2; font2.fromString("Arial,10,-1,0,50,0,0,0,0,0,Regular"); qDebug() << font2.family() << font2.pointSize() << font2.bold() << font2.italic(); // Output: "Arial" 10 false false }
