[vtkusers] SetProgressMethod

[Andrew Maclean]

Does anyone use SetProgressMethod() in their C++ code to inform users of the
progress of a filter? If so would they be prepared to show me an example of
the use of this?
I am currently using MSC VC++ and I have prototyped something like this:



            Surf[i]->SetStartMethod( StartProcess, this);
            Surf[i]->SetProgressMethod(ShowProgressSurf, (void *)Surf[i]);
            Surf[i]->SetEndMethod( EndProcess, this);



////////////////////////////////////////////////////////////////

void StartProcess(void *pArg)
{
            CMultipleSurfaceRendererDoc *MyThis =
(CMultipleSurfaceRendererDoc *)pArg;
            MyThis->BeginWaitCursor();
            WriteToStatusBar(_T("Processing..."));


}

void EndProcess(void *pArg)
{
            CMultipleSurfaceRendererDoc *MyThis =
(CMultipleSurfaceRendererDoc *)pArg;
            MyThis->EndWaitCursor();
            WriteToStatusBar(_T(""));
}

void ShowProgressSurf(void *arg)
{
            vtkSurfaceReconstructionFilter *self =
(vtkSurfaceReconstructionFilter *)(arg);
            TRACE("progress: %f\n",self->GetProgress());
}


Do I have to construct a separate ShowProgress for each filter? Or is there
some way of constructing a more general one?
Is it also possible to pass text to these filters e.g a CString value?


Thanks for any hints,

    Andrew
