 error: calls to overloaded operators cannot appear in a constant-expression
 
 code snippet:

 public:
   /// Supported selections flags. These are a subset of

 Clear  = QItemSelectionModel::Clear,
 Select = QItemSelectionModel::Select,
 Deselect   = QItemSelectionModel::Deselect,
 ClearAndSelect = Clear | Select

Looks like gcc cannot resolve Clear and Select to a
constant-expression and you'll need to spell out the
scope. Try changing the line above to:
ClearAndSelect = QItemSelectionModel::Clear | QItemSelectionModel::Select

Hope this helps,

I did try that, but no go.  I think the | operator is overloaded somewhere.

I guess that Q_DECLARE_FLAGS macro for QItemSelectionModel overrides
this operator.

Possible workaround for it would be:

ClearAndSelect = static_castint(Clear) | static_castint(Select)
