PathGetter - 6.0

This is a function that allows the user to enter a valid file path like in a file browser.
It returns a string.
Browse with mouse or keyboard. It supports tab-completion.
You can also display a resizable and rotatable image preview.

Usage is very simple:
     In a python script: PathGetter(path='',mode=None,caption='Path Getter')

mode = None ==> any path
mode = 1 ==> file path
mode = 2 ==> directory path

The code is executed in a separated window using the subprocess module.
Therefore, it's independent of the size of your window.

see example_pathgetter.py for example
