如何使用QTreeView获取所选项目的详细信息?

I'm using QTreeView with QDirModel like this:

我使用QTreeView和QDirModel是这样的:

QDirModel * model = new QDirModel;
ui->treeView->setModel(model);
ui->treeView->setSelectionMode(QTreeView::ExtendedSelection);
ui->treeView->setSelectionBehavior(QTreeView::SelectRows);

This works fine, however, I'm not sure how to get the details about the files I select. I've got this so far:

但是，我不确定如何获得我所选择的文件的详细信息。到目前为止，我已经做到了:

QModelIndexList list = ui->treeView->selectionModel()->selectedIndexes();

But not sure what to do now, I'd like to get each file's name and full path. An example would be really great. Thank you.

但是不知道现在该怎么做，我想获取每个文件的名称和完整路径。举个例子真是太棒了。谢谢你！

you can use fileInfo method of the QDirModel to get file details for the given model index object, smth like this:

您可以使用QDirModel的fileInfo方法获取给定模型索引对象的文件详细信息，如下图所示:

QModelIndexList list = ui->treeView->selectionModel()->selectedIndexes();
QDirModel* model = (QDirModel*)ui->treeView->model();
int row = -1;
foreach (QModelIndex index, list)
{
    if (index.row()!=row && index.column()==0)
    {
        QFileInfo fileInfo = model->fileInfo(index);
        qDebug() << fileInfo.fileName() << '\n';
        row = index.row();
    }
}

hope this helps, regards
