Hi Christian,
ParaView/VTK uses a specialized parser tuned for vtk, and this parser has
some assumptions , and in particular all class names must start with
"vtk", thus your classes starting with ivtk or xtk will not be accepted by
the parser. You can try to exclude the offending lines from the parsing
using //BTX //ETX , but it would be simpler if you keep the "vtk" prefix.
Other limitations :
the parser will complain if you include more than only the superclass
header in your header file (and commits to vtk itself will be rejected
unless you add comments explaining why you had to add those includes)
templated ivars must be between //BTX //ETX
Some usefull references :

Best,

[Paraview] Another Syntax Error - ParaView Plugins
Hello!
I am writng a plugin for my paraview. I already succeeded doing this
with another filter but this one drives me crazy. I keep getting these
"*** SYNTAX ERROR found in parsing the header file
/home/christian/programming/pv-plugins/Transformation/ivtkSampleFilter.h
before line 8 ***
messages, no matter where I put these //BTX //ETX. This is my header:
#ifndef IVTK_SAMPLE_FILTER
#define IVTK_SAMPLE_FILTER
#include "vtkObjectFactory.h"
#include "vtkSimpleImageToImageFilter.h"
#include "xtkBox.h"
class VTK_IMAGING_EXPORT ivtkSampleImageFilter : public
vtkSimpleImageToImageFilter {
public:
static ivtkSampleImageFilter* New();
vtkTypeMacro( ivtkSampleImageFilter, vtkSimpleImageToImageFilter);
protected:
ivtkSampleImageFilter();
ivtkSampleImageFilter(const ivtkSampleImageFilter&) {};
void operator=(const ivtkSampleImageFilter&) {};
//override from vtkImageToImageFilter
virtual void SimpleExecute(vtkImageData* inp, vtkImageData* out);
//BTX
vtkImageData* vtkResultImage;
//ETX
vtkITKFilter_H_Macro;
/// custom Filter function ///
template <typename ImageType>
void ApplyFilter(vtkImageData* vtkInput);
};
#endif
It also complains if I comment out my #include "xtkBox.h", or put some
//BTX//ETX all around other places. It keeps coming with the error
message as if I did not even edit the right file. (I do, I checked
that... :)
I call a macro later in the header which is defined in the xtkBox.h but
the compiler does not even care if it is defined or not. Anyway, for
completeness I attached this xtkBox.h.
Does anyone see what I am missing?
Best regards,
Chrsitian
