1 在编程中，若是想设置QTableWidget为不可编辑，则使用如下代码即可：
setEditTriggers(QAbstractItemView::NoEditTriggers);
2 由QTableWidget引申：
因为QTableWidget继承自QAbstractItemView，而QAbstractItemView方法setEditTriggers可以设置是否可以编辑，因此只要是继承自QAbstractItemView的其它类控件都可以设置为可否编辑，而且方法一致，如1所示。
QAbstractItemView的编辑触发事件如下：
| Constant | Value | Description |
|---|---|---|
| QAbstractItemView::NoEditTriggers | 0 | No editing possible. |
| QAbstractItemView::CurrentChanged | 1 | Editing start whenever current item changes. |
| QAbstractItemView::DoubleClicked | 2 | Editing starts when an item is double clicked. |
| QAbstractItemView::SelectedClicked | 4 | Editing starts when clicking on an already selected item. |
| QAbstractItemView::EditKeyPressed | 8 | Editing starts when the platform edit key has been pressed over an item. |
| QAbstractItemView::AnyKeyPressed | 16 | Editing starts when any key is pressed over an item. |
| QAbstractItemView::AllEditTriggers | 31 | Editing starts for all above actions. |
