Solved 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!
