[vtkusers] VTK interactor has changed?

[imho]

Hi all,
as I said I try to upgrade from 4.0 to 4.2, and additionnally to my heap 
problem  I have a class vtkInteractorStyleCustom : public 
vtkInteractorStyle, and some things working before are no missing...

thanks for helping :/

the code :
------------------------------------------------------
void vtkInteractorStyleCustom::OnLeftButtonDown(int ctrl, int shift, int 
x, int y)
{
    this->FindPokedRenderer(x, y);
    if (this->CurrentRenderer == NULL)
    {
        return;
    }

    int * xy= this->CurrentRenderer->GetRenderWindow()->GetSize();
   
    width=xy[0]/2;
    height=xy[1]/2;

    if (reslice && (x<=width) && (y>=height))
    {
        double positionX = x;
        double positionY = y - height ;
        double spacing = hg->getSpacing();

        double slice = 
(double)((positionX-(width/2))/(double)((width/2)/spacing));
        double slice2 = 
(double)(((positionY)-(height/2))/(double)((height/2)/spacing));
       
        bg->setSpacing(slice);
        bd->setSpacing2(slice2);
    }
    else
    {
        this->UpdateInternalState(ctrl, shift, x, y);
 
        this->FindPokedCamera(x, y);
        if (this->HasObserver(vtkCommand::LeftButtonPressEvent))
        {
            this->InvokeEvent(vtkCommand::LeftButtonPressEvent,NULL);
        }
        else
        {
            if (this->ShiftKey)
            { //// I haven't got a Middle button !
                if (this->CtrlKey)
                {
                    this->StartDolly();
                }
                else
                {
                    this->StartPan();
                }
