QT_STRINGIFY ( arg )
The macro can be used to turn the builtin line expander arg into a string literal.
Q_UNUSED ( name )
Indicates to the compiler that the parameter with the specified name is not used in the body of a function. This can be used to suppress compiler warnings while allowing functions to be defined with meaningful parameter names in their signatures.
