Detailed Description

\inmodule QtCore

The QMetaClassInfo class provides additional information about a class.

Class information items are simple {name}–{value} pairs that are specified using Q_CLASSINFO() in the source code. The information can be retrieved using name() and value(). For example:

class MyClass
{
Q_OBJECT
Q_CLASSINFO("author", "Sabrina Schweinsteiger")
Q_CLASSINFO("url", "http://doc.moosesoft.co.uk/1.0/")
public:
...
};
Q_OBJECT
#define Q_OBJECT
Definition qtmetamacros.h:117
Q_CLASSINFO
#define Q_CLASSINFO(name, value)
Definition qtmetamacros.h:52
url
QUrl url("example.com")
[constructor-url-reference]
Definition src_corelib_io_qurl.cpp:19

This mechanism is free for you to use in your Qt applications. Qt doesn't use it for any of its classes.
