one type of file format in QTreeView

Is it possible to set only one file format visible to the user? I'm searching it in documentation, but I can't find it... If not, which other widget you are suggesting to use?

Solution

  • I assume you're using a QTreeView with a QFileSystemModel. If not, I'd suggest doing so. QTreeWidget is not as flexible.

    QFileSystemModel has a method called setNameFilters that should do what you want. To use it, do something like this:

    QStringList filters;
filters.append("*.cc"); // whatever filters you want
filters.append("*.h");

QFileSystemModel *model = new QFileSystemModel;
model->setNameFilters(filters);

QTreeView *view = new QTreeView;
view->setModel(model);
