I have a QString fileName which stores in it a path to a subdirectory (eg. C:/Qt). I also have a treeView inside a dialog box.
Upon starting the application, we browse a file and once the file/folder is selected, I save the path of the file/folder in fileName string.

Upon clicking "OK" (QPushButton), I intend to open a new Dialog Box divided into a treeView displaying the subdirectory with the selected folder as the root node of the tree, and a listView displaying all the files/folders within that folder and nothing if empty.

I used the following QFileSystemModel functions to display the C:/ directory (only drive on my pc) :

What I have tried:

QString path;

//QFileSystemModel *dirModel;
//QFileSystemModel *fileModel;
//TreeView
dirModel = new QFileSystemModel;
dirModel->setFilter(QDir::NoDotAndDotDot | QDir::AllDirs);
dirModel->setRootPath(path);
ui->treeView->setModel(dirModel);

//ListView
fileModel = new QFileSystemModel;
fileModel->setFilter(QDir::NoDotAndDotDot | QDir::Files);
fileModel->setRootPath(path);
ui->listView->setModel(fileModel);


If I set the path to fileName (QString path = fileName;), nothing changes. I'm assuming QDir::AllDirs is the reason for this.

I looked for other QDir filters (like QDir::Dirs or setFilter) but nothing seems to work. I even tried QDesktopServices::openUrl, but it just opens the file path in a new window instead of the treeView.
