"""
Example code to select file using a file dialog.

Needs a Qt Application object and then a File dialog object.
The `getOpenFileName()` method on the file dialog object opens
a dialog for loading a single file. It returns a tuple, containing
the selected file name (str) and the filter (str).
If no file was selected (cancelled), you get empty strings in the tuple.
