QFileDialog - about the behavior of "QFileDialog::Directory" and "QFileDialog::ExistingFile".

Firstly, I'm sorry if my English is hard to understand.

http://doc.qt.io/qt-5/qfiledialog.html#FileMode-enum
This document descrives that "QFileDialog::Directory" is both files and directories, and "QFileDialog::ExistingFile" is single existing file.
Then I wrote a minimal sample program like below but I can not understand its behavior.
(OS is Linux)

#include <QApplication>
#include <QFileDialog>
int main( int argc , char *argv[] ) {
    QApplication app( argc , argv ) ;
    QFileDialog dialog;
    dialog.setFileMode( QFileDialog::Directory ) ;
//    dialog.setFileMode( QFileDialog::ExistingFile ) ;
    dialog.show() ;
    return app.exec() ;
    
}

When I use QFileDialog::Directory, only directories are shown in the dialog.
And when I use QFileDialog::ExistingFile, both files and directories are shown in the dialog.
It seems that it is contrary to the document.

Is this a documentation bug?
Or am I something wrong...?

@tyamada said in QFileDialog - about the behavior of "QFileDialog::Directory" and "QFileDialog::ExistingFile".:

And when I use QFileDialog::ExistingFile, both files and directories are shown in the dialog.

I expect that the dialog is showing directories, so that you can navigate into one of them in order to select an existing file within it.

Cheers.

Ah, I understood it, thanks!

But about the behavior of "QFileDialog::Directory", when I use qt4, it displays both files and directories as the document described(and as I expected).
When I use qt5, it displays only directory.

So I suspect this is maybe qt5 bug.
I'll try to report it to bugtracker.

Thank you very much!
