Don't show hidden files with QFileSystemModel

ivanicy

Hello!!

Is there a way to not show hidden files and folders with a QFileSystemModel?

I am showing a lot of files that are not necessary and bother.

Thank you very much!

@ivanicy What about https://doc.qt.io/qt-5/qfilesystemmodel.html#setFilter ?

@jsulm Is there a way to hide all files and directories starting with "."? It is that they do not appear as hidden files with the explorer

jsulm

@ivanicy Yes, just spend a minute to read the link a gave you then you will also see https://doc.qt.io/qt-5/qdir.html#Filter-enum

@jsulm I don't mean the directory . and ..
I mean, for example, the .cache directory

@ivanicy said in Don't show hidden files with QFileSystemModel:

.cache

This is a hidden file/folder on UNIX/Linux, so QDir::Hidden is what you need...

ivanicy

@jsulm Yeah, in Unix, but in Windows this folder appears like a "normal" folder, not a hidden folder, so I think I have to hide it manually...

QDir::Hidden means files/directories beginning with . under Linux but with Hidden attribute under Windows. If you are under Windows and a file/directory starts with a . (and does not have Hidden attribute set) you will need to write code to exclude it.

Having said that, I do not actually see in QFileSystemModel any facility for you to exclude/filter out file names starting with . under Windows. I don't think the setNameFilters() method will let you achieve that.

You might instead achieve the filtering/exclusion for the purpose of not viewing such files/directories by, say, interposing some QAbstractProxyModel between your QFileSystemModel and whatever view you attach, e.g. QSortFilterProxyModel::setFilterRegularExpression(const QString &pattern) or sub-classed bool QSortFilterProxyModel::filterAcceptsRow(int source_row, const QModelIndex &source_parent) const, could be used to exclude items starting with a . in their name. I note that e.g. https://stackoverflow.com/questions/11454248/how-to-exclude-dirs-in-qfilesystemmodel says to do just this sort of thing. Similarly the comment in https://stackoverflow.com/a/4927222/489865 points you to https://stackoverflow.com/questions/4893122/filtering-in-qfiledialog which also takes the same approach.
