使QTreeWidgetItem的仅一列可编辑 [英] Making only one column of a QTreeWidgetItem editable

问题描述

我有一个包含两列数据的QTreeWidgetItem，有什么方法可以使仅第二列可编辑吗?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);

所有列都可编辑.

推荐答案

看起来您将不得不放弃使用QTreeWidget和QTreeWidgetItem并使用QTreeView和QAbstractItemModel. 窗口小部件"类是便捷类，它们是更抽象但更灵活的版本的具体实现. QAbstractItemModel调用flags(QModelIndex index)，您将在其中为列返回适当的值.

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.
