C++ (Cpp) convert_QStringList_to_PyListObject Examples

Example #1

PyObject* scribus_getpropertynames(PyObject* /*self*/, PyObject* args, PyObject* kw)

	int includesuper = 1;
	char* kwargs[] = {const_cast<char*>("object"),

	QObject* obj = getQObjectFromPyArg(objArg);

	// Retrive the object's meta object so we can query it
//qt4 FIXME	const QMetaObject* objmeta = obj->metaObject();

	// Return the list of properties
	QStringList propertyNames;
//qt4 FIXME	propertNames = objmeta->propertyNames(includesuper);
