仅使 QTreeWidgetItem 的一列可编辑
我有一个带有两列数据的 QTreeWidgetItem，有什么办法可以只编辑第二列?当我执行以下操作时:
I have a QTreeWidgetItem with two columns of data, is there any way to make only the second column editable? When I do the following:
QTreeWidgetItem* item = new QTreeWidgetItem();
item->setFlags(item->flags() | Qt::ItemIsEditable);
所有列都可以编辑.
推荐答案
看起来你将不得不放弃使用 QTreeWidget 和 QTreeWidgetItem 而使用 QTreeView 和 QAbstractItemModel.Widget"类是便利类，它们是更抽象但更灵活版本的具体实现.QAbstractItemModel 有一个调用 flags(QModelIndex index)，您可以在其中为您的列返回适当的值.
Looks like you will have to forgo using QTreeWidget and QTreeWidgetItem and go with QTreeView and QAbstractItemModel. The "Widget" classes are convenience classes that are concrete implementations of the more abstract but more flexible versions. QAbstractItemModel has a call flags(QModelIndex index) where you would return the appropriate value for your column.
