class grphD::App
{
    ...

    protected:
        class 
        {
            ...
        } console_handler;

        class
        {
            ...
        } grid;
};

How can I access App::console_handler inside App::grid functions without having console_handler static and keeping console_handler an object of an anonymous class?

Not standard C++ - `warning: anonymous structs are a GNU extension [-Wgnu-anonymous-struct] ` – Richard Critten Aug 21 '20 at 16:19
So it's better to name the class also if I'm gonna use it only once? – DarkoNaito_09 Aug 21 '20 at 16:25
Does `grid` know anything at all about (i.e., have access to) the `App` object it is a member of? – 1201ProgramAlarm Aug 21 '20 at 17:54
`decltype(console_handler)` might help. But giving it a type name would probably be better. – Eljay Aug 21 '20 at 17:55
@1201ProgramAlarm grid is a member of App – DarkoNaito_09 Aug 21 '20 at 18:00
But `grid` is a class object that has no knowledge of or access to the parent class, so it can't access anything in `App`. Did you add something to give it that access? – 1201ProgramAlarm Aug 21 '20 at 18:02
@1201ProgramAlarm I didn't. I thought it would've automatically gained access to App members, maybe prefixing them with App:: – DarkoNaito_09 Aug 21 '20 at 18:04
Btw, if anonymous classes are not part of standard C++ I think I'll just give them a name. – DarkoNaito_09 Aug 21 '20 at 18:08
