Yes, of course, I asked here because I thought it should be an
out-of-the-box way to do this.

BTW, I'm subclassing a QVTKWidget, where I have methods like this:

void  MYWidget::addMeasure()
{
  mynewwidget = vtkDistanceWidget::New();
}

I think its easier to add a collection class member for my widget to
store the list of widgets. The question is, is there a predefined
collection class for storing widgets?.
