I think it’s unreasonable for a library to require preprocessing of my source code

  • 0

I think it’s unreasonable for a library to require preprocessing of my source code with a special tool. That said, several people have recommended the Qt library to me for cross platform GUI development.

How usable is Qt without the preprocessing step?

EDIT: Okay people, I’m not meaning this question as a rip on Qt — too many Qt fanboys are treating it as if it is. I don’t want to discuss the merits of the fact that Qt came up with this preprocessing tool. I understand why the tool is there, and I understand why there are large parts of Qt’s design that are built upon the idea of preprocessing.

I’ve never used Qt, ergo I am in no position to rip on it. But I would much rather pay in writing a small amount of boilerplate myself and not depend on ripping apart my entire build process. I won’t use Flex and Bison in my current project for the same reason; if I won’t use those tools, I’m definitely not going to use another kind of preprocessing.

So, please don’t take me as ripping on Qt. I cannot comment on how nice or not nice it is; I have not used it. I just want to know if it is possible to use it without moc.

    Qt doesn’t require the use of moc just to use it, it requires that usage if you create a subclass of QObject, and to declare signals and slots in your custom classes.

    It’s not unreasonable, moc provides features that C++ doesn’t have, signals/slots, introspection, etc.

    So, to do something minimally advanced, you WILL have to use the moc preprocessor. You either love it, or hate it.
