多项选择QTreeWidget [英] Multiple Selection QTreeWidget

问题描述

有人知道是否有可能在QTreeWidget上选择多个项目以及如何启用多个选择吗?

Does anyone know if its possible to select multiple items on a QTreeWidget and how to go about enabling the multiple selection?

我要选择的所有项目都是顶级QTreeWidgetItems，所有子项都设置为禁用(即QTreeWidgetItem.setDisabled(True))

All the items I want to be selectable are top level QTreeWidgetItems and all their children are set to be disabled (i.e QTreeWidgetItem.setDisabled(True) )

推荐答案

是的，您将要调用

It is, you'll want to call setSelectionMode during init to enable QAbstractItemView::MultiSelection. QTreeView/QTreeWidget inherit QAbstractItemView, so it is available.

然后要禁用这些项目，只需挂接到QTreeWidgets.itemSelectionChanged()信号即可.

Then to disable the items, just hook on to QTreeWidgets.itemSelectionChanged() signal.
