Model changed view not updated
Message 1 in thread
Hello list,
i have a Model derived from QAbstractTableModel. In it is a QSqlDatabse
Member. I know there is a QSqlTableModel but i dont want to use it since the
Columns in the View are not the same Columns of the Sql Database. Actually
the Columns in the View/Model are fixed (5).
My Model now Implements rowCount() using a select on the QSqlDatabase Member.
I olso have a setFilter() function which should work as the setFilter from
QSqlTableModel. The rowCount respects the filter returning the correct number
of rows.
My Problem now is, the View does not get noticed about the changed rows. Where
would i emit layoutChanged()? I have emit'ed it in my setFilter Function, but
without success. Do i have to connect the layoutChanged() with the view
manualy? Or do i have to emit it somewhere else? The View is a standard
QTableView.
