推荐答案

这取决于selectionMode，可以说您具有ExtendedSelection，这意味着您可以选择任意数量的项(包括0).

It depends on selectionMode lets say you have ExtendedSelection which means you can select any number of items (including 0).

ui->listView->setSelectionMode(QAbstractItemView::ExtendedSelection);

您应该遍历ui->listView->selectionModel()->selectedIndexes()以找到所选项目的索引，然后调用text()方法以获取项目文本:

you should iterate through ui->listView->selectionModel()->selectedIndexes() to find indexes of selected items, and then call text() method to get item texts:

QStringList list;
foreach(const QModelIndex &index, 
        ui->listView->selectionModel()->selectedIndexes())
    list.append(model->itemFromIndex(index)->text());
qDebug() << list.join(",");
