Cope & Run FourPaneViewer Demo in QtCreator with cmake

Hello,

Custom classes derived from VTK classes must often follow some formalities so they can be managed by the VTK framework.

Here is how I declared (.h) a class derived from vtkInteractorStyleTrackballCamera:

#include <vtkObjectFactory.h>
#include <vtkInteractorStyleTrackballCamera.h>
#include <vtkSmartPointer.h>
#include ...
#include ...

class myMouseInteractor : public vtkInteractorStyleTrackballCamera
{
public:
    static myMouseInteractor* New();
    vtkTypeMacro(myMouseInteractor, vtkInteractorStyleTrackballCamera)

    virtual void OnLeftButtonDown();

    virtual void OnLeftButtonUp();

    virtual void ...;

    virtual void ...;
...
};

And here is how I defined (.cpp) it:

#include "mymouseinteractor.h"

#include ...
#include ...

// Implementation of the New() function for this class.
vtkStandardNewMacro(myMouseInteractor);

void myMouseInteractor::OnLeftButtonDown()
{ ...
}

void ...

...
