camel case or underscores or mixed?
-
I noticed Qt creator uses mixed styles and I was wondering if a reason existed for this.
It generates signals/slots that use underscores and all classes and functions seem to be camel case. Is this standard? Is this what I should do as a Qt developer?
Is this in the docs some where?
Thanks

Hi @Goddard,
It generates signals/slots that use underscores and all classes and functions seem to be camel case.
What do you mean by it "generates signal/slots"? I'm a bit of a Qt Creator n00b - just use it as a glorified text editor most of the time, so I'm not familiar with its code generation abilities, but what you describe does sound odd.
Is this standard? Is this what I should do as a Qt developer?
I'd say not. Most (all?) of the Qt classes use camelCase for signals; eg QObject::objectNameChanged.
It generates signals/slots that use underscores and all classes and functions seem to be camel case.
So while you're welcome (AFAIK) to use any style you like, I certainly wouldn't say underscores are recommended just based on whatever Qt Creator behaviour you're seeing.
Cheers.

As a developer in general, you are free to do whatever you want. Pick your preferred style and stick to it. The most important thing is to be consistent.
Qt Designer's auto-connector uses underscores. Unfortunately, this is inconsistent with Qt's coding conventions. Qt's public API uses camel casing only, not underscores.
Personally, I don't use the auto-connector.

No good reason, really.

I personally prefer camelcase, as underscore reminds me too much of C and its many quirks, and to be honest I don't see adding extra underscores as improvement on readability. Still, as JKSH said, it's just a matter of preference and you're free to choose what suits you best.

Too magic for me either ...

After some time working with a giant project that uses Qt, MFC, STL nad WinAPI in different parts all I can say is that naming convention doesn't really make a difference, just do yourself a giant favor and pick one and stick to it.
And I wouldn't use the auto connection feature. It might be tempting for people used to visual designers like in C# or Delphi, but it's quite different in details and not particularly good for maintenance anyway (renaming, refactoring etc).
