Easy File Selection

Here is a trick to let you easily select a file "graphically" for a console based application, when launched from a menu in a window manager. It uses Python and two modules that are delivered with the standard distribution.

The following example launches the "mplayer" media player with a selected file:


import subprocess
import tkFileDialog

file = tkFileDialog.askopenfilename()
if len(file) > 0:
    subprocess.call(["mplayer", file])

Instead of launching the application directly, create a script like this and point the menu entry towards that instead.
