[Paraview] Commands for Source Plugin

[Jérôme]

Hi,
First of all, your public virtual function is called 'SetNuberOfXBin'
whereas the XML try to
find SetNumberOfXBins. If this is a copy/paste from your real code, you would
have to check your syntax.

Second, the XML describes an IntegerVectorProperty with 10 elements, thus
I expected to find a function in your VTK class of the form:
   SetNumberOfBins( int, int, int, int, int, int, int, int, int, int );

For clarity purpose (I don't know how mandatory it is), I would then declare
the default values as default_values="1 1 1 1 1 1 1 1 1 1 1".

Really, I don't understand what you are trying to do. Usually, a SetNumberOf...
is described as
                <IntegerVectorProperty name="NumberOfXBins"
                                                   command="SetNumberOfXBins"
                                                   number_of_elements="1"
                                                   default_values="1">
                   <IntRangeDomain name="range" min="0">
                </IntegerVectorProperty>

And your VTK class should implement a public function
    void SetNumberOfXBins( int n );
The better being to use a vtkSetMacro for a basic accessor method. But you may
have some additional processing when setting the value, making vtkSetMacro
unsufficient : in this case, don't forget to call Modified( ) in your
Set method unless
the pipeline won't update accordingly to your expectations.
