   \class qdesigner_internal::ItemViewPropertySheet

   \brief
     Adds header fake properties to QTreeView and QTableView objects

     QHeaderView objects are currently not shown in the object inspector.
     This class adds some fake properties to the property sheet
     of QTreeView and QTableView objects that nevertheless allow the manipulation
     of the headers attached to the item view object.

     Currently the defaultAlignment property is not shown because the property sheet
     would only show integers, instead of the Qt::Alignment enumeration.

     The fake properties here need special handling in QDesignerResource, uiloader and uic.
