class Q_CORE_EXPORT QFlag

[Shriramana Sharma <samjnaa@gmail.com>]

I see many usages in the Qt sources like:

class Q_CORE_EXPORT QFlag
{
	<blah blah blah>
} ;

Isn't the word immediately next to the keyword class supposed to be the 
class name? Q_CORE_EXPORT etc are certainly not class names. What are 
they and how are they allowed in between the word class and the class name?

I searched my "Thinking in C++" for this but did not turn up an answer. 
Please help.

Thanks as always,

Shriramana Sharma.
