*
* This model is currently only used by WTreeView, and plays only
* a role in drag & drop of an item selection.
*
* When an item selection is dragged from a view widget, the generated
* drop events will have as source object (see WDropEvent::source())
* this selection model.
*
* Although this class does not (yet) allow you to modify the
* selection, note that manipulations to the model may modify the
* selection (row insertions and removals may shift the selection, and
* row deletions may shrink the selection).
*
* \note Currently this class cannot be shared between multiple views.
