Is it possible to use Qt without dynamic memory management? I want to use pools for everything.

It would be especially welcome feature for embedded development, where memory is constrained and I want to make sure that I have enough for everything. Even if I waste a little memory when for example two features are never used simultaneously but I reserve space for both of them. Still its better than an application which seems to work until it doesn't. I just need to be sure. And by "use pools for everything" I mean everything. All those little objects like QSharedPointer control block or connection or something else should also be pool-managed.

Sounds like you need to use your own implementation of new then?

Thanks. Hadn't thought of of that. Do you think that anyone has done anything like this or similar? I now I didn't but I'll be happy to try.

I don't know, never tried something like this myself...

Hi,

IIRC, there was qMalloc, qFree and qRealloc meant for that use case

Problem is: those were deprecated years ago.

Sorry for the old pointer. They are not only deprecated but also not used anymore in Qt 5.
