[Paraview-developers] custom object panel with additional information

[Sebastien Jourdain]

What was your method profile before?

double* GetPlaneC()
void GetPlaneC(double* coefs)
void GetPlaneC(double &a, double &b...)

If you use the vector macro in your code. That should work. Or at least the same profile(s).
