如何设置qtablewidget 垂直表头宽度为固定的大小

Answer 1

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：

[cpp] view plaincopy
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：

QAbstractItemView::DoubleClicked 2 Editing starts when an item is double clicked.

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.
