get complete path of the file selected in QTreeView

[AmrCoder]

Hello,
I have a QTreeView which I use it with QFileSystemModel to get all the files in the directory. using this code

    QFileSystemModel *model = new QFileSystemModel;
    model->setRootPath(QDir::currentPath()); //any path
    ui->treeView->setModel(model);
    ui->treeView->setRootIndex(model->index(QDir::currentPath())); // to show only this path

and I created a signal for click on the QTreeView to get the selected file from it

void MainWindow::on_treeView_clicked(const QModelIndex &index)
{
    qDebug() << "row = " << index.row() << " - column = " << index.column();
    qDebug() << "Item = " << ui->treeView->model()->data(index).toString();
}

I got only the name of the file pure without its full path.

1 - my question here how can i get the full path of the file when the user select an item from the tree.

2 - also a second question is there any way to filter the shown files in the directories?

I tried to setFilter to the model but this only filter the full type of the file like the show only files or directory I want to filter it in the way in which I only choose the file extension to show only the mp3 file or mp4 only and so on.
Thanks in advance.

Hi,

Isn't what QFileSystemModel::filePath does ?

Thank you this worked I made the model global and I can access the file full path using this function in the QTreeView click signal.
do you know how I can set filter depends on the file extension to be shown?
I tried something like this on my model

model->setFilter(QDir::Files);

but I don't want that I want to filter only the file extension every file in his own directory.
something like this

model->setFilter("*.mp3 .*mp4");

or similar

Why make your model a global variable ?

You can use QSortFilterProxyModel for sorting/filtering/etc..

@AmrCoder

model->setFilter("*.mp3 .*mp4");

For this you want setNameFilters() rather than setFilter().
See http://doc.qt.io/qt-5/qfilesystemmodel.html#setNameFilters
