Description Olaf Flebbe 2001-03-08 16:34:43 EST
From Bugzilla Helper:
User-Agent: Mozilla/4.76 [de] (X11; U; Linux 2.4.1 i686)


The code at The Code at the url gets an error  when compiling 
IMHO gcc-2.96-69 is incorrect.

Workaround is to profix QObject with :: .



Reproducible: Always
Steps to Reproduce:
1. g++ a.cpp

	

Actual Results:  a.cpp: In method
`pig_enhanced_QSignal::pig_enhanced_QSignal
(QObject *)':
a.cpp:1: `class QObject' is inaccessible
a.cpp:12: within this context


Expected Results:  It should compile

gcc-2.95.2 and SGI CC does compile it.

It should not compile, it is not valid ISO C++ code.
he name QObject is injected into class QObject, so it becomes a
private member of class QSignal, hiding the global definition of QObject in
classes derived from QSignal.
Using ::QObject there is not a workaround, it is how it should have been coded.
