[Qt5-feedback] Merging QDeclarative specifics into core QMetaObject

[Stefan Majewsky]

Hi,

I was thinking about using QML to define internal datastructures (e.g.
as a more powerful alternative to QSettings). While doing so, I came
to wonder whether some of QtDeclarative's custom additions to the
metaobject framework should be merged into the main macros.

For example:
> Q_PROPERTY(QObject* foo READ foo WRITE setFoo NOTIFY fooChanged)
> Q_CLASSINFO("DefaultProperty", "foo")

could become:
> Q_PROPERTY(QObject* foo READ foo WRITE setFoo NOTIFY fooChanged DEFAULT)

It might also make sense to introduce a Q_LIST_PROPERTY() macro to
avoid most of the QDeclarativeListProperty boilerplate. Same for
grouped properties etc.

Greetings
Stefan
