Hi!

I don't know, if this is the right place to ask about smoke, so if it's not or if you know a better place, please tell me.

I toyed around with smoke to get information about the Qt-library (inheritance structure, method descriptions, etc.). I am doing this from Haskell (http://haskell.org). The ultimate goal would be, to generate bindings to be able to use Qt-libs from Haskell. I imagine, one would use smoke to gather information about Qt and from that, generate C- and Haskell-files that would make up a Haskell-Qt-library. So, is this doable with smoke? Is there a better way?

I tried to look up documentation about smoke on the net, but there isn't much. There is no project homepage, no API-docs, just one (helpful) example on techbase. So i have some questions regarding the API:

1. How can i gather information about enumeration types in Qt (for example: QApplication::Type)?

2. It says, the field Smoke::Type.classId is set to (- 1) if the type is not a class. I wasn't able to find the value (- 1) for classId in any of the types. I had the impression, that not (- 1) but 0 was used to identify non-class types (as is the case in the types for "int" and "bool"). However the following types, that represent classes, expose 0 in their classId-field: "QString", "QThread*", "const QList<QObject*>&", "QList<QByteArray>", "QList<QPair<int,int> >", "EventFilter".
What also bothers me here: a classId == 0 would, afaik, refer to qt_Smoke->classes[0]. But that doesn't seem to be a class (I get a segfault for qt_Smoke->classes[0].className), which makes perfectly sense, if classId == 0 is used to indicate non-classes. But isn't there a better way to handle this? What if i want to iterate over all classes?

3. It seems that the void type is indicated by Type.name being the null pointer, but that's just guessing. Is that true?

btw: I am using version 4.3.4. Is there anything happening in smoke in the svn-repo?


I think, smoke is a great piece of software and it's a pity that it isn't better documented (and missing some convenience functions) and i would like to help. So who can i talk to about that?

Hi,

You should send this to the kde-bindings maillist where the Smoke developers are: kde-bindings@kde.org

Yes, that is the way to work with Smoke to make a Qt binding. In SVN there is a new Smoke generator written in C++ that will be released with the KDE compilation 4.4. It includes Qt 4.6 support and it is more modular.

Ok, thanks. Will check out the svn version and ask the list, if needed.

I should say this is new what you are talking about it. I would check this version too. Thanks for sharing it!!!
