The container classes are implicitly shared, they are reentrant, and they are optimized for speed, low memory consumption, and minimal inline code expansion, resulting in smaller executables. In addition, they are thread-safe in situations where they are used as read-only containers by all threads...

The ISO C++ Standard specifies that all virtual methods of a class that are not pure-virtual must be defined, but does not require any diagnostic for violations of this rule [class.virtual]/8. Based on this assumption, GCC will only emit the implicitly defined constructors, the assignment op...
Use Q_MOC_INCLUDE to tell the Meta Object Compiler (MOC) to add an include when you’ve forward declared types used in properties, signals, and slots. For example, you must add Q_MOC_INCLUDE(“MapQuickView.h”) to your header if exposing MapQuickView as a Q_PROPERTY. QML signals mus...
