Pyface filedialog does not use native file dialog and (thus) cannot see remote path (UNC path)

[taoism-coder]

I tested PyQt4 QFileDialog, it uses the native FileDialog in both macOS and Windows 10 . Below is how I test PyQt4 FileDialog:

from PyQt4 import QtGui
import sys

QtGui.QApplication(sys.argv)
QtGui.QFileDialog.getOpenFileName()
sys.exit(app.exec_())

Below is how I use pyface FileDialog:

from pyface.api import FileDialog, OK
dlg = FileDialog(action='open')
if dlg.open() == OK:
    pass

Apparently this may be an issue with Qt: https://stackoverflow.com/questions/53410896/pyside-qtgui-qfiledialog-unc-path-issue

I have tested it. PyQt4 works fine. Maybe it is the problem of PySide?

Sorry - I missed that.

This is the call to the file dialog in Pyface: https://github.com/enthought/pyface/blob/master/pyface/ui/qt4/file_dialog.py#L136 It gets opened in a separate call after it is created.

Is it failing after closure, or just not allowing you to find the path? What happens with PyQt5?

[taoism-coder]

pyface opens a different File Dialog that are not native and cannot see the UNC or any network location.

PyQt5 also works fine.
