I'm trying to make a binding for a trivial test class:
#include <QGLWidget>
class Math : public QGLWidget
{
Q_OBJECT
public:
Math() {}
virtual ~Math() {}
int squared(int x);
signals:
void aSignal(QPoint, QSize);
};
I have a typesystem file for the binding:
<?xml version="1.0"?>
<typesystem package="foo">
<load-typesystem name="typesystem_core.xml" generate="no"/>
<load-typesystem name="typesystem_opengl.xml" generate="no"/>
<object-type name="Math"/>
</typesystem>
When I run this through shiboken I get the following
WARNING :: signal 'aSignal' in non-QObject class 'Math'
WARNING :: unknown baseclass for 'Math': 'QGLWidget'
WARNING :: type 'QFontDialog' is specified in typesystem, but not
defined. This could potentially lead to compilation errors.
.... lots more of the last warning...
Does someone have a working example of a trivial binding using shiboken
I could look at?
Check if the header that you used with the generator (global.h) have the
includes for QtCore, QtGui and QtOpenGL modules, and if the include paths are
correct.
These problems are due the parser did not find the class declarations of
QObject, QWidget and QGLWidget.
Right. That got me a little further. It still fails, but is down to a
hand full of warnings:

My typesystem_VideoWidget.xml is now:
<?xml version="1.0"?>
<typesystem package="VideoWidget">
<load-typesystem name="typesystem_core.xml" generate="no"/>
<load-typesystem name="typesystem_opengl.xml" generate="no"/>
<load-typesystem name="typesystem_gui.xml" generate="no"/>
<object-type name="VideoPlayerWidget"/>
</typesystem>
And my global.h is:
#undef QT_NO_STL
#undef QT_NO_STL_WCHAR
#ifndef NULL
#define NULL 0
#endif
#include <QtCore/QtCore>
#include <QtGui/QtGui>
#include <QtOpenGL/QGLWidget>
#include "../../VideoPlayerWidget.hpp"
Do I need to include more headers?
I also noticed that if <typesystem package="VideoWidget"> and
<object-type name="VideoWidget"/> have the same value then shiboken
complains about a duplicate class definition. Is that correct behavior?
Thanks for the help so far.
