I am deleting one item from QFileSystemModel but it's not updated
immediately, when I click on other item then I can see that it's deleted
from the model.
QFileSystemModel *model = new QFileSystemModel;
model->setRootPath(QDir::currentPath());
QTreeView *tree = new QTreeView(this);
tree->setmodel(
I have QFileSystemModel in my QTreeView. When click on a directory in the
model I want to enable the name to be edited just like windows folders. How
can I make it enabled and let user write the new name. Any help is
appreciated.

In the case that your computation is massive, you may want to change your
concurrency design. You can add a writer thread to be the only one who
talks to database. Other threads write their manipulated data into a
mutex-guarded shared data structure (say a queue). Then the writer thread
can write d

To the best of my knowledge, I think you're right: of course Qt should
not need to handle fiducials, so it makes sense that it lacks support
