  Subject: [vtkusers] Getting the progress state of a process object - What'swrong with this?


  Hi all,
  I'd like to link my VTK processes to a progressbar which in the statusbar. I think my code is almost OK, hopefully there shouldn't be much to change.
  What my code does:
  I created a class (derived from vtkCommand) and overrode the virtual Execute() method.
  In my code I use ProcessObject->AddObserver(vtkCommand::ProgressEvent,&Proc) method (where Proc is an instance of the class derived from vtkCommand).
  This works fine, because the overridden Execute() method gets called every time the process object starts but I don't know how to get the current state of progress (it should be a fraction between 0 and 1).
  How do I get it? I tried "this->GetProgress()" but didn't compile...

  Here's the code:

  ----------------------------------------------------------------
  The header file of the class CProgressObserver:
  ----------------------------------------------------------------

  class CProgressObserver : public vtkCommand {
  public:
  static CProgressObserver* New() {
   return new CProgressObserver;
  }
  virtual void Execute(vtkObject* caller, unsigned long, void *callData) {
   double* dProgress = (double*)(callData);
      
    //The progressbar is in the MainFrame
    CMainFrame* pFrame = (CMainFrame*) AfxGetApp()->m_pMainWnd;
      CStatusProgress* setprogress = &pFrame->progress; 

    //Here I'd like to set the progressbar to the actual progress of my processobject
    setprogress->SetPos(?????);
  }
  };

  ----------------------------------------------------------------
  Later in my code:
  ----------------------------------------------------------------
   
    CProgressObserver Proc;
    CProgressObserverEnd ProcEnd;
    m_openclose->AddObserver(vtkCommand::ProgressEvent,&Proc); 


  Any help would be greatly appreciated,
   Esseigaz
