PassRefPtr frame = frameTree->firstChild(); frame->loadRequest(request, false, newLoadID, 0, 0);
PassRefPtr frame = m_page->mainFrame(); frame->loader().stopAllLoaders();This code snippet also uses PassRefPtr to manage the allocation of a Frame object from the WebKit package library. The Frame object is assigned to the smart pointer variable named "frame", and the stopAllLoaders() method is called on the object's loader. Overall, PassRefPtr is a useful tool for managing dynamic memory allocations in C++ programs that use package libraries like WebKit.
