KUrl url1; // create empty KUrl object if (url1.isNull()) { cout << "The URL is null." << endl; } else { cout << "The URL is " << url1.url() << endl; }
KUrl url2("https://www.example.com/"); // create KUrl object with a URL if (url2.isNull()) { cout << "The URL is null." << endl; } else { cout << "The URL is " << url2.url() << endl; }This code creates a non-empty KUrl object with a URL and checks if it is null, then outputs a message accordingly. The KURL class is part of the KIO (KDE Input/Output) package library in C++.
