q_slots - C++ Qt Signals and Slots 888 casino slot machine

Since display() is part of the class's interface with the rest of the program, the slot is public. ... The public API of Qt-based libraries should use the keywords Q_SIGNALS and Q_SLOTS instead of signals and slots.

PS: The slot and the signal have been properly declared in header files using the Q_SIGNALS and Q_SLOTS keywords, with the correct argument (aStruct).

The public API of Qt-based libraries should use the keywords Q_SIGNALS and Q_SLOTS instead of signals and slots. Otherwise it is hard to use such a library in a project that defines QT_NO_KEYWORDS.
