[vtkusers] BorderWidget with mouse

Hi, I'm testing vtkBorderWidget but I don't like the results I'm
getting.

This code places a borderWidget in a QVTKwidget, then I can manipulate
it with the mouse:

    borderWidget = vtkBorderWidget::New();
    borderWidget->SetInteractor(this->GetInteractor());
    borderWidget->CreateDefaultRepresentation();
    borderWidget->On();

What I would like is to let the user pick a point in the QVTKWidget,
then start dragging to create a box, like many drawing programs do. When
the box is created, the user should resize it (vtkBorderWidget already
does this), and, when the user click inside the borderWidget and drag
the mouse, the widget should move until the user stop dragging.

Does anybody knows how can I get this behavior? or a similar widget that
alows me to do this?.
