Dear all, I'm using CDT 2.1RC0 to develop QT applications.
QT use this signals/slots mechanism, therefore you do find the macro
"slots" and "signals" in the classes declaration, for instance:

class Test : public QObject
{
public:
Test();
~Test();
private slots:
void mySlot();
signals:
void mySignal();
}

However the CDT parser failed to register the class whenever it finds
the word "signals" or "slots" in the class declaration. Is there anyway
to configure the parser to ignore them and still register this as a
class or I have to dig into the code?

In Project Peoperties -> C/C++ Include Paths & Symbols press Add
Preprocessor Symbol button and type in signals=/*signals*/. Repeat the
same with slots

Maybe this helps

Indeed, that works fine now, thanks ever so much.

But are not those things define somewhere in a qt header, for all to use.
maybe the problem is that this file was not included i.e. #include
qt_macros.h
are something ?

Yes, however, they are defined as:

#define signal
#define slot

so perhaps they cannot be properly interpreted?

not knowing anything about QT : note that even if signals & slots are
#defined away, the below code would be preprocessed as:
....
private : //ok
void mySlot();
: //not ok
void mySignal();

with the given code, you would need to #define signals as one of public,
protected, private.

Hello guys,

Propably it is not anymore usefull for you, but what i do to get it work is the following:

first i add the path that vaias said before:

"In Project Peoperties -> C/C++ Include Paths & Symbols press Add
Preprocessor Symbol button and type in signals=/*signals*/. Repeat the
same with slots "

And then i add
#define signals
#define slots

as well as the declaration of the slot: (for example)

private slots:
void on_Ok_clicked();

on the ui_AddressBook.h

finally the code for the on_Ok_clicked() on the AddresBook.cpp.

I hope it is gonna help someone....

It is not necessary to add the defines manually. You should add the include path for Qt in Project Peoperties -> C/C++ General->Include Paths & Symbols->Includes (C++). Eclipse will then find the correct headers and can resolve the symbols.
