QTableView - not allow user to edit cell
提问by Berschi
I created a QTableView with a QSqlTableModel. By standard, double-clicking on the cells will mark them and the user can edit them. I want, that the user isn't allowed to do that. He is allowed to mark the whole row by clicking on a single cell, but not to edit the cell. How can I do that?
我用 QSqlTableModel 创建了一个 QTableView。按照标准，双击单元格将标记它们并且用户可以编辑它们。我想要，不允许用户这样做。他可以通过单击单个单元格来标记整行，但不能编辑该单元格。我怎样才能做到这一点？

Depending on whether you are coding everything or doing things in the designer, set
根据你是在编码一切还是在设计器中做事，设置
editTriggerstoQAbstractItemView::NoEditTriggersselectionBehaviortoQAbstractItemView::SelectRows- optionally set
selectionModetoQAbstractItemView::SingleSelectionif you want the user to select exactly one row
editTriggers到QAbstractItemView::NoEditTriggersselectionBehavior到QAbstractItemView::SelectRows- 如果您希望用户只选择一行
selectionMode，QAbstractItemView::SingleSelection则可以选择设置为
on the tableview object the appropriate calls will all be prefixed with sete.g setEditTriggers()in the Designer you can find these option in the AbstractItemViewsection
在 tableview 对象上，适当的调用都将带有前缀，set例如setEditTriggers()在设计器中，您可以在AbstractItemView部分中找到这些选项

Try this:
尝试这个：
table->setEditTriggers(QAbstractItemView::NoEditTriggers);

Toggle off the table item's ItemIsEditablebit. e.g.:
关闭表格项目的ItemIsEditable位。例如：
QTableWidgetItem* item = new QTableWidgetItem(...);
...
item->setFlags(item->flags() &= ~Qt::ItemIsEditable);

Ideally you will want to use:
理想情况下，您将希望使用：
void QAbstractItemView::setItemDelegate ( QAbstractItemDelegate * delegate )
And then create a class that inherits from QItemDelegatelike in thisexample.
Editing your class to have
然后创建一个类继承自QItemDelegate像这样的例子。编辑你的班级
QWidget * QItemDelegate::createEditor ( QWidget * parent, const QStyleOptionViewItem & option, const QModelIndex & index ) const
return NULL
返回 NULL
or use:
或使用：
table->setEditTriggers(QAbstractItemView::NoEditTriggers);
You will also want to look at
你还想看看
void setSelectionBehavior ( QAbstractItemView::SelectionBehavior behavior )
With the parameter: QAbstractItemView::SelectRows
带参数： QAbstractItemView::SelectRows
