[Paraview-developers] Problem with plugins build from an inherited class

[Joe Ping-Lin Hsiao]

I found a workaround.

I compiled vktITKImageFilter as a static library, and linked the plugins
with the library rather than included its source code.

This would avoid the crashing and allows me to load both plugins at the
beginning. But I'd get the following error when applying the plugins:


ERROR: In
..\..\..\..\..\src\ParaView\ParaViewCore\ServerImplementation\Core\vtkPVSessionCore.cxx,
line 389

vtkPVSessionCore (00000000044669B0): Object type:
vtkGaussianBlurImageFilter, could not find requested method:
"SetInputConnection"

or the method was called with incorrect arguments.


while processing

Message 0 = Invoke

Argument 0 = vtk_object_pointer {vtkGaussianBlurImageFilter
(000000000B70C310)}

Argument 1 = string_value {SetInputConnection}

Argument 2 = vtk_object_pointer {vtkAlgorithmOutput (000000000637B500)}


I had to explicitly implement the SetInputConnection() functions

void SetInputConnection(int port, vtkAlgorithmOutput* input)
{vtkImageAlgorithm::SetInputConnection(port, input);}
  void SetInputConnection(vtkAlgorithmOutput* input)
{vtkImageAlgorithm::SetInputConnection(input);}

inside my plugins' headers to avoid the error.
