qt4到qt5使用qsqltablemodel的变化

查到了qt5的变更列表，在设计qsqltablemodel时有下面变化。

1. QtSql
2. -----
3. QSqlQueryModel/QSqlTableModel/QSqlRelationalTableModel
5. * The dataChanged() signal is now emitted for changes made to an inserted
6. record that has not yet been committed. Previously, dataChanged() was
7. suppressed in this case for OnRowChange and OnFieldChange. This was probably
8. an attempt to avoid trouble if setData() was called while handling
9. primeInsert(). By emitting dataChanged(), we ensure that all views are aware
10. of the change.
12. * While handling primeInsert() signal, the record must be manipulated using
13. the provided reference. Do not attempt to manipulate the records using the
14. model methods setData() or setRecord().
16. * removeRows() no longer emits extra beforeDelete signal for out of range row.
18. * removeRows() now requires the whole range of targetted rows to be valid
19. before doing anything. Previously, it would remove what it could and
20. ignore the rest of the range.
22. * removeRows(), for OnFieldChange and OnRowChange, allows only 1 row to be
23. removed and only if there are no other changed rows.
25. * setRecord() and insertRecord()
26. -The generated flags from the source record are preserved in the model
27. and determine which fields are included when changes are applied to
28. the database.
29. -Require all fields to map correctly. Previously fields that didn't
30. map were simply ignored.
31. -For OnManualSubmit, insertRecord() no longer leaves behind an empty
32. row if setRecord() fails.
33. -setRecord() now automatically submits for OnRowChange.
35. * QSqlQueryModel::indexInQuery() is now virtual. See
36. QSqlTableModel::indexInQuery() as example of how to implement in a
37. subclass.
39. * QSqlQueryMode::setQuery() emits fewer signals. The modelAboutToBeReset()
40. and modelReset() signals suffice to inform views that they must reinterrogate
41. the model.
43. * QSqlTableModel::select() is now a slot.
45. * QSqlTableModel::selectRow(): This is a new slot that refreshes a single
46. row in the model from the database.
48. * QSqlTableModel edit strategies OnFieldChange/OnRowChange QTBUG-2875
49. Previously, after changes were submitted in these edit strategies, select()
50. was called which removed and inserted all rows. This ruined navigation
51. in QTableView. Now, with these edit strategies, there is no implicit select()
52. done after committing. This includes deleted rows which remain in
53. the model as blank rows until the application calls select(). Instead,
54. selectRow() is called to refresh only the affected row.
56. * QSqlTableModel::isDirty(): New overloaded method to check whether model
57. has any changes to submit. QTBUG-3108
59. * QSqlTableModel::setData() and setRecord() no longer revert pending changes
60. that fail upon resubmitting for edit strategies OnFieldChange and OnRowChange.
61. Instead, pending (failed) changes cause new changes inappropriate to the
62. edit strategy to be refused. The application should resolve or revert pending
63. changes. insertRows() and insertRecord() also respect the edit strategy.
65. * QSqlTableModel::setData() and setRecord() in OnRowChange no longer have the
66. side effect of submitting the cached row when invoked on a different row.
68. * QSqlDriver::subscribeToNotification, unsubscribeFromNotification,
69. subscribedToNotifications, isIdentifierEscaped, and stripDelimiters
70. are now virtual. Their xxxImplemenation counterparts have been removed
71. now that QSqlDriver subclasses can reimplement these directly.

也就是说在setResord的时候需要将所有字段都匹配？
