Qt: QFileSystemModel Filter Out Directories (not files) by expression

Question

How can i filter out Folders? I looked for QDir::Filters here: but i cannot see how to filter by expression. I Want to Hide Folders Starting with "A00*"

enter image description here

I tried to use nameFilters, but then the folders are just becoming grey:

QStringList filters;
filters <<"Cloth";
dirModel->setNameFilters(filters);

enter image description here

What if you try to set `dirModel->setNameFilterDisables(false);`? — vahancho, Nov 12 '14 at 09:40
Can you please write this as an answer? And how can i inverse the expression? — user1767754, Nov 12 '14 at 09:47
Why not create a subclass of ProxyModel and just create your own filter to not display desired directories — Sebastian Lange, Nov 12 '14 at 09:49

There is a QFileSystemModel's property that defines how items (files, directories) should be visualized is they do not pass the name filter. It is nameFilterDisables. By default this property is true, i.e. items that do not pass the name filter are disabled. For your case you have to disable this property to make non filtered items hidden:

dirModel->setNameFilterDisables(false);
