[PySide] binding qwt-6.0.1 with shiboken, got stuck on template class...

[Grissiom]

Hi all,

I forked halida's pysideqwt on github(
https://github.com/grissiom/pysideqwt ) and working on binding
Qwt-6.0.1. I made some adjustment on the typesystem_qwt.xml and
global.h to suppress most of the generator warnings. But I got error
when compiling. Here is the full log:

==========================================================

==================================================================

I think the error indicate shiboken could not cope with the template
class QwtArraySeriesData. But as it is a base template class for many
others( http://qwt.sourceforge.net/class_qwt_array_series_data.html ),
I think I could not go any further without solve this problem.

I'm new to pyside and shiboken. Any help will be appreciated thanks!

hi, all

I just forked https://github.com/grissiom/pysideqwt and pushed my changes.

I got build 100% pass, but not the test results due to C++ templates.

Here is my fork: https://github.com/yinhm/pysideqwt

It based on Qwt 6.1.0-svn.

I have the same question with Grissiom, here is the build log related to templates:

{{{

Resolving typedefs...                        [OK]

Fixing class inheritance...                  [WARNING]

class not found for setup inheritance 'QGraphicsObject'

template baseclass 'QwtPlotSeriesItem<QwtIntervalSample>' of 'QwtPlotIntervalCurve' is not known

class 'QGraphicsWidget' inherits from unknown base class 'QGraphicsObject'

template baseclass 'QwtSeriesData<QPointF>' of 'QwtCPointerData' is not known

class 'QGraphicsTextItem' inherits from unknown base class 'QGraphicsObject'

template baseclass 'QwtArraySeriesData<QwtSetSample>' of 'QwtSetSeriesData' is not known

template baseclass 'QwtArraySeriesData<QPointF>' of 'QwtPointSeriesData' is not known

template baseclass 'QwtArraySeriesData<QwtPoint3D>' of 'QwtPoint3DSeriesData' is not known

template baseclass 'QwtPlotSeriesItem<QPointF>' of 'QwtPlotCurve' is not known

template baseclass 'QwtSeriesData<QPointF>' of 'QwtPointArrayData' is not known

template baseclass 'QwtPlotSeriesItem<QwtIntervalSample>' of 'QwtPlotHistogram' is not known

template baseclass 'QwtSeriesData<QPointF>' of 'QwtSyntheticPointData' is not known

template baseclass 'QwtArraySeriesData<QwtOHLCSample>' of 'QwtTradingChartData' is not known

template baseclass 'QwtPlotSeriesItem<QwtPoint3D>' of 'QwtPlotSpectroCurve' is not known

template baseclass 'QwtArraySeriesData<QwtIntervalSample>' of 'QwtIntervalSeriesData' is not known

}}}

For example, The QwtPlotCurve definition:

  class QWT_EXPORT QwtPlotCurve: public QwtPlotSeriesItem<QPointF>

QwtPlotSeriesItem which is the class using template:

  class QWT_EXPORT QwtPlotAbstractSeriesItem: public QwtPlotItem

  template <typename T>

  class QwtPlotSeriesItem: public QwtPlotAbstractSeriesItem

And the QwtPlotItem:

  class QWT_EXPORT QwtPlotItem: public QwtLegendItemManager

CTest failed due to some method in QwtPlotItem did exposed to QwtPlotCurve:

{{{

1: ERROR: testQwt (__main__.QwtTest)

1: Test case for qwtplot class from qwt module.

1: ----------------------------------------------------------------------

1: Traceback (most recent call last):

1:   File "/home/josh/quant/qwt/pysideqwt/tests/qwt_test.py", line 32, in testQwt

1:     curve.attach(plot)

1: AttributeError: 'PySideQwt.QwtPlotCurve' object has no attribute 'attach'

}}}

So, my question is, what should I do to make attach method available in QwtPlotCurve or

how do I convert C++ template to shiboken definitions.

Hi,

I tried to compile the project but without success so far.

According to the README.txt file, the following command should be sufficient to make the build:

$ make install  

However when you look at the makefile, the following line:

cd build_object; $(MAKE)

cannot work (there is no 'build_object' directory in the tree).

Prior to running the makefile, I ran the following command : "cmake ." - it went fine. 

I then tried to go into the qwt subdirectory and run make. It starts well but fail here:

(...)

Could not find a minimal constructor for type 'Array'. This will result in a compilation error.
Aborted
make[2]: *** [qwt/PySideQwt/pysideqwt_module_wrapper.cpp] Error 134

make[1]: *** [qwt/CMakeFiles/PySideQwt.dir/all] Error 2
make: *** [all] Error 2

I am not sure what I could have done wrong - I am not very familiar with shiboken yet.

Have you experienced this issue?

Thanks for any help you could provide
