I'm trying to capture key presses so that when a given combination is pressed I trigger an event.
I've searched around for tips on how to get started and the simplest code snippet I can find is in Python - I grabbed the code below for it from here. However, when I run this from a terminal and hit some keys, after the "Press a key..." statement nothing happens.
Am I being stupid? Can anyone explain why nothing happens, or suggest a better way of achieving this on Linux (any language considered!)?
import Tkinter as tk
def key(event):
if event.keysym == 'Escape':
root.destroy()
print event.char
root = tk.Tk()
print "Press a key (Escape key to exit):"
root.bind_all('<Key>', key)
# don't show the tk window
root.withdraw()
root.mainloop()
Well, turns out there is a much simpler answer when using GNOME which doesn't involve any programming at all...

Just create the script/executable to be triggered by the key combination and point the 'keybinding_commands' entry you create in gconf-editor at it.
Why didn't I think of that earlier?
