如何使用QTreeView获取有关所选项目的详细信息？

Question

I'm using QTreeView with QDirModel like this:

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:

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.

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

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
