[Paraview] Problems with user defined filter

[Moreland, Kenneth]

How are you trying to use your filter?  Are you trying to define it in a ParaView plugin?  If so, you should be able to leave out any of the _EXPORT declarations and it should work OK.

I write a filter class just like the vtkAppendFilter ,and change a little on the mothod RequestData ..My class also inherited from vtkUnstructuredGridAlgorithm .I did the job all on windows vs2008.The vtkAppendFilter.h defines the class with VTK_GRAPHICS_EXPORT which means __declspec( dllimport ) on my computer,but if I used that macro to define my own filter class it would met some link errors .If I use the macro VTK_EXPORT or did not use macro to  define my filter class ,it can complie well,but it did not work.I tried the debug.I found it would not invoke my RequestData function at all,and the it would not invoke vtkUnstructuredGridAlgorithm'RequestData methord either.The program invoked the method RequestData form vtkAlgorithm class directly.I don't know why? what should I do if want to define my own filter? Thanks a lot!
