PythonQt has moved to GitHub:

The SF site will stay around, but will not get updates anymore.

Florian, glad to see you are keeping a watch on things. I tried adding this line to the pp-qt-configuration file but it doesn't seem to have any affect.

#define QT_DEPRECATED QT_DEPRECATED

I would think that I should be able to set breakpoints in preprocessor.cpp but they never get called.

I'm not having a lot of luck yet. I thought that I could add some code to check for QT_DEPRECATED on a function but it's not getting called. It seems that there is a pre-processor that is removing the QT_DEPRECATED token from the source. It looks like the prepocessor code is QT code that I can't see so I've been unable to see how it's doing this.

repo on github would be nice. makes it much easier to cooperate.

In the next couple of days, I should be able to take a look at some of the problems. What if I setup a repository on github for my changes? That should make it easier to shae any changes we make.

Me too. I already make a big part of our application scriptable, but the bugs that you mentioned produce a lot of trouble.

Maybe we can cooperate to fix he bugs.

I only got involved with PythonQt because I wanted to add scripting capabilities to a QT program.

I also think that the endif warning is from an pythonqt parser bug. The strange thing is that i get it only when i add additional include directories. The parser sometimes does not see classes, but they are listed in the preprocess file.

yeah, there are some weird bugs which need some checks.

Do you use pythonqt only for qt stuff or do you use it for your own code as well (as i do)?

I don't believe that the "#endif without #if" problems are appearing because of a real poblem in the input header files but a bug in the PythonQT parser. It may be an indication of some classes not being processed properly. I sort of got sidetracked on other issues and haven't wlooked into any of these issues.

At the present time, the failure od QSignalMapper as I previously posted about is my biggest concern. My next item of interest is figuring out how to ignore methods marked QT_DEPRECATED.

Of the two fixes that I posted, one is merely cosmetic, eliminating the generation of an unnecessary ";" on a generated code. The other is to include QWidgets in the include path for QT classes.

I'e also identified some other things that should be checked, like whether supplied include paths are valid.
