Darn, okay, I'll keep digging. Thanks Justin.

 Hi all, my apologies if this isn't the right place to ask this, but I'm
 at my wits end and I'm sure I'm missing something simple here. I'm trying
 to use Shiboken to build Python bindings. I'm using the widget example on
 Qt's website:

 http://doc.qt.io/qt-5/qtwidgets-widgets-analogclock-example.html

 and when I run shiboken2 on the class, I get a litany of (I assume
 benign) warnings, like:

 qt.shiboken: type 'QSizeF' is specified in typesystem, but not defined.
 This could potentially lead to compilation errors.

 The reject log for the classes is the precise class I needed wrapped,
 with the message, "Type redefined to not be a class". It's unclear to me
 why this is happening, does anyone here have any ideas?

 Thank you for your time,
 Ravi

No need to apologize. I have to offer my sympathy for your journey into
shiboken-land.

Actually what you get from shiboken is more headers and cpp wrapper files,
which you then compile as a plugin linking against python, to produce a
python compiled extension. So there are more steps, and no py files
unfortunately.

To simplify:

C++ headers -> shiboken -> wrapper headers/source
C++ headers/source + wrapper headers/source -> link Python -> myExt.so

Re: [Maya-Python] shiboken warnings and missing classes

[Ravi Jagannadhan]

Hi Justin, thanks. The issue seems to be in the typesystem XML file, I
didn't add the object line. My next question, and I'm really sorry for how
stupid this will sound is Shiboken supposed to generate .py files? Or
is there some other process that makes them?

Ravi

Re: [Maya-Python] shiboken warnings and missing classes

[Justin Israel]

Hey Ravi,

I have worked on a project that provides shiboken 1/2 python bindings, and
my experience with shiboken is that it is poorly documented and hard to use
:-/ And to be honest, the huge number of warnings you are seeing is
something we are used to as well. A build of our project shows more than
900 warnings, but still functions as it is meant to. I see things like:

   - enum does not have a type entry...
   - Unable to decide type of property:
   - namespace does not have type entry
   - skipping field..
   - skipping function...
   - horribly broken type ''
   - signal is overloaded
   - class inherits from unknown base class
   - template baseclass is not known
   - Shadowing:
   - visibility of function modified in class
   - hiding of function in class
   - type is specified in typesystem but not defined

That last one *could* imply that you have specified a type in your xml file
that was given to shiboken, but the headers defining that type haven't been
provided.

Using shiboken is a dark art.

Justin
