\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.
