template <typename T> auto qConstOverload(T memberFunctionPointer)

Returns the memberFunctionPointer pointer to a constant member function:

     struct Foo {
         void overloadedFunction(int, const QString &);
         void overloadedFunction(int, const QString &) const;
     };
     ... qConstOverload<int, const QString &>(&Foo::overloadedFunction)
     ... qNonConstOverload<int, const QString &>(&Foo::overloadedFunction)

template <typename T> auto qNonConstOverload(T memberFunctionPointer)

Returns the memberFunctionPointer pointer to a non-constant member function:

     struct Foo {
         void overloadedFunction(int, const QString &);
         void overloadedFunction(int, const QString &) const;
     };
     ... qConstOverload<int, const QString &>(&Foo::overloadedFunction)
     ... qNonConstOverload<int, const QString &>(&Foo::overloadedFunction)

template <typename T> auto qOverload(T functionPointer)

Returns a pointer to an overloaded function. The template parameter is the list of the argument types of the function. functionPointer is the pointer to the (member) function:

     struct Foo {
         void overloadedFunction();
         void overloadedFunction(int, const QString &);
     };
     ... qOverload<>(&Foo::overloadedFunction)
     ... qOverload<int, const QString &>(&Foo::overloadedFunction)

If a member function is also const-overloaded qConstOverload and qNonConstOverload need to be used.
