QFileDialog to only show executable files in Linux

[qlands]

I have a QFileDialog that I want only to select executable files. Here is the code:

QFileDialog selectFile(this,title);
    selectFile.setFilter(QDir::Files | QDir::Executable);
    selectFile.setDirectory(path);
    selectFile.setFileMode(QFileDialog::ExistingFile);
    if (selectFile.exec())
          qDebug() << selectFile.selectedFiles();

QFileDialog selectFile(this,title);
    selectFile.setFilter(QDir::Files | QDir::Executable);
    selectFile.setDirectory(path);
    selectFile.setFileMode(QFileDialog::ExistingFile);
    if (selectFile.exec())
          qDebug() << selectFile.selectedFiles();

To copy to clipboard, switch view to plain text mode 

However I can see all files if I run it in Linux. Any idea how to correct it?

This is interesting, different implementations bahve differently.

With XDG_CURRENT_DESKTOP=KDE I get all files, as you do.

When I run this with XDG_CURRENT_DESKTOP=GNOME I get no files at all.
When I set the QFileDialog::Options to include DontUseNativeDialog I also get not files at all.

I added QDir::Readable to the filter, now GNOME and Non-Native dialog show programs, but seem to not show scripts that are marked executable.

Edit: ah, I think the two latter are actually the same thing (non-native dialog), just differently styled.

Cheers,
