Description Eugene Rudenko 2009-12-01 14:13:20 UTC

Hello.
There are problem while importing Qt-based sources.
Umbrello parse Q_OBJECT macro incorrect. For example such code:

class MyClass: public QObject
{
    Q_OBJECT
public:
    void method1();
...................

While parsing I got "Q_OBJECTpublic" class in my tree and method1 is private of course, because "public" directive was incorrectly translated.

Also It will be good to understand base Qt's macros while importing the source code, such as Q_DECLARE_PUBLIC, Q_DECLARE_PRIVATE, Q_Q, Q_D, SIGNALS, SLOTS, QFLAG, QPROPERTY and so on.

The bug is also present on windows in recent svn code, which means that umbrello is currently unusable for importing any qt based code. This includes the whole kde base.
Comment 2 Ralf Habacker 2011-12-27 07:29:17 UTC
This bug is fixed in the kdevelop4 cpp parser.
Comment 3 Ralf Habacker 2012-01-04 11:02:03 UTC
Further analysis shows that the lexer, which is based on boost::spirit, returned  'Q_OBJECT' concated with the following term 'public:'.

I tried to follow the calls into the boost spirit library, but get lost in the very deep call tree. 

When this worked before (which I assume) I guess that the problem is caused by a bug or internal change in newer versions of the boost::spirit parser. 

In case of an internal change it may be that there is a different or additional boost::spirit setup required, which umbrello does not follow.
Comment 4 Ralf Habacker 2012-01-04 11:05:35 UTC
To be complete: 

I also tried to add Q_OBJECT to the "lexer should skip word" list, but this do not fix the problem. 

In the lexer code there are also some hardcoded checks for Q_.. related stuff, where I added Q_OBJECT; unfortunally without any success.

Pushed by habacker into branch 'master'.

Add debug support to class Parser, Lexer and PreprocessLexer.

This should help to find cpp parse problems easier.

Debug support can be enabled for several classes through the debug window (STRG-D).
