Qtreewidget selected item index. void QTreeWidget::addTopLevelItem(QTreeWidgetItem *item) Appends the item as a top-level item in the widget. row() was a bit of a shot in the dark, but it seems to ignore the various branches in the tree (for instance, it will give me a 0 for the first row in a branch, but won't tell me anything about what branch it's in). For example, the following code constructs a top-level item to represent cities of the world, and adds a entry for Oslo as a child item: We would like to show you a description here but the site won’t allow us. The QTreeWidgetItem class is a convenience class that replaces the QListViewItem class in Qt 3. It will not go anywhere near overflowing the stack for any imaginable depth. And May 13, 2015 ยท I am trying to make a functionality, that will select the last item in the QTreeView, if there are no items selected. Items are usually constructed with a parent that is either a QTreeWidget (for top-level items) or a QTreeWidgetItem (for items on lower levels of the tree). void QTreeWidget::addTopLevelItems(const QList &items) Appends the list of items as a top-level items in the widget. I don't know how to select an item within the program. I think the only way to handle with that is using selectedItems and IndexFromItem: @QTreeWidget* treewidget; // some code QTreeWidgetItem *QTreeWidget:: topLevelItem (int index) const Returns the top level item at the given index, or nullptr if the item does not exist. koqpaefcbglfesrfvsbqtmfibvhvkxfmvelwzabnp
