Showing filesystem in QTreeWidget

Question

I have a simple Question. I want to show my filesystem in a QTreeWidget just like an common file explorer.

How can i achieve that? I guess searching through all files and add them manual is not the approach to chose, right?

Answer 1

use QDirModel and QTreeView instead of QTreeWidget, here is a code snippet:

QDirModel *model = new QDirModel;
QTreeView *tree = new QTreeView(splitter);  
tree->setModel(model);  
tree->setRootIndex(model->index("C:\\"));
