Access single instance from all class

hiren21

I am trying to access awesome object from another class . I declare this in main()

int main(int argc, char *argv[])
{
    QApplication app(argc, argv);
    QtAwesome* awesome = new QtAwesome(&app);
    awesome->initFontAwesome();
    app.setWindowIcon(awesome->icon( "clipboard" ));
    Login w;
    w.show();

    return app.exec();
}

Now how do I access awesome object from Login or another class ? Is it best way to initialize a class in main() if I want to access from another class ?

Pass the pointer to Login class in some method.

If you want to have a global, single instance object, take a look at Singleton pattern. Just a word of warning: singletons add global state to the application, which makes testing and bug fixing harder (sometimes) - I recommend keeping singleton numbers as low as possible.

Hi @hiren21

You can pass awesome pointer to login class when you create a object of login.

login w(awesome);

Thanks.
