[SailfishDevel] Problem with SearchField hiding and clearing on text entry

Hi Tadeusz,

Although Qt docs don't mention it specifically, I suspect that
QSqlTableModel's setFilter method resets the model causing the attached
views redrawing themselves, including their headers. You clould use a
QSortFilterProxyModel which would not reset upon setting its filter,
resulting in the desired behaviour.

Regards Kris
