设置QTableWidget为不可编辑

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.
