You cannot create a script engine (and many other Qt objects) as long as you haven’t created a Q(Core)Application.
- int main(int argc, char *argv[])
- {
- MainWindow w;
- w.show();
- return a.exec();
- }
Passing the script engine as a global variable is a very questionable design decision. A better choice would be subclassing QApplication and adding it as a member or storing it as a property of QApplication (the QApplication instance is accessible from anywhere using qApp() or QCoreApplication::instance()).
