An IliDbNavigator gadget contains a set of buttons that can be used to act on the data source that the gadget is connected to. The data source is specified by one of the following member functions: IliFieldItf::f_setDataSourceName or IliFieldItf::f_setDataSource. The gadget contains the following buttons:
GotoFirst GotoPrevious GotoNext GotoLast StartInsert DeleteRow Validate Cancel Select Clear QueryMode The two read-only text fields are:
Position RowsCount | IliDbNavigator::IliDbNavigator | ( | IlvDisplay * | display, |
