Hi all,
Qyoto now uses read-only properties instead of methods where methods have no \
parameters and are only assumed to return a value. It is Brian Crowell's idea and \
initial work. Binaries are not uploaded yet.
Brian, I've used parts of your code but there are 2 major changes you should know \
about: 1. I've decided to change the approach from enumerating properties to \
enumerating verbs, as I mentioned earlier - the reasoning is that now there's no need \
to manually scan the huge Qt API for property-like methods; also, it turned out \
pretty easy to do. There are categorised dictionaries only so I only had to get one, \
leave only the single-worded verbs that are not also nouns using a few regular \
expressions, and the result was a text file of only 108 K/11 500 lines which doesn't \
slow the build significantly. I'd like to hear in more detail your opinion so that \
the disadvantages this approach may have are noted and fixed; 2. I haven't committed \
the "Get" prefix on methods yet. I've found an unpleasant bug with property \
generation which I'd like to fix beforehand. It is old, it's just that I noticed it \
while merging and changing your code. The problem is that in some cases methods \
shadow properties. The case I've found is that QObject has a Parent property, and the \
QAbstractItemModel, which inherits from QObject, generates a Parent() method which \
shadows the property. Once I fix this I'll work on integrating your "Get" part as \
well.
Regards,
Dimitar
