QTreeView with QFileSystemModel not sorting

[Diracsbracket]

Hi,
I have a QTreeView for a QFileSystemModel in which I only keep the Name column visible.

I have set

m_dirTree->setSortingEnabled(true);
m_dirTree->sortByColumn(index.column(), Qt::AscendingOrder);

and use the following to add a subfolder to the currently selected folder:

index = m_treeModel->mkdir(index, foldername);

The view is updated to show the newly added folder, but it is appended at the end of the subdir list. So even if I name my new folder AA, it will still show after ZZZ.

Forcing a sort by clicking on the header's sort arrow does not correct this either?
What is going on?

QObject::connect(m_treeModel,&QAbstractItemModel::dataChanged,[=]()->void {m_treeModel->sort(0);});

@VRonin said in QTreeView with QFileSystemModel not sorting:

QObject::connect(m_treeModel,&QAbstractItemModel::dataChanged,=->void {m_treeModel->sort(0);});

Thanks @VRonin .

I tried you connect, and the slot is called, but the sort has no effect.

The thing is, when I create the AA folder manually in Explorer, the tree updates correctly and shows AA at the top. So maybe I should try using another method to make the directory than

QFileSysModel::mkdir()

Indeed, when I use QDir::mkdirI() the model updates to the correct sort order...

Coincidentally, I had the same problem as you before.

Define that: m_model is the object of class QFileSystemModel, and m_rootpath is the root path of your filetree.

In the constructor function of QTreeView, there should be the following code:

m_model->setRootPath(m_rootpath);
setModel(m_model);
setRootIndex(m_model->index(m_rootpath));

Add the following code where you have done the file operation.

m_model->setRootPath("");
m_model->setRootPath(m_rootpath);

The method WORKS in my project !
