I'm not sure I understand the question right. It appears to be a question
purely about SWT widgets.
  - Paint events are sent by SWT to the affected SWT control only, not
    to its parents (assuming the parent is opaque). If you want that
    notification, you'll have to add a PaintListener to the control
    explicitly.
  - Notification about resized controls happens like this: The code that
    changes the size of a Control is also responsible for picking one
    of the ancestor of the control and invoking
      ancestor.layout(new Control[] { control });
    on it. The control is not supposed to propagate its size changes to
    its parent automatically.

If this does not answer your question, you may give a code sample to
highlight what you mean.
