A function callback every time a key is pressed (regardless of which window has focus)?


I want to write a programme (in python) on Linux (Ubuntu Linux 9.10) that will keep track of how many key presses per second/minute I make. This includes normal letter keys, and control/shift/space/etc.

Is there some way to hook into X so that I can say "when a key is pressed call this function?". Since I want to have this running in the background while I work normally, this function call will have to be able to be aware of all key presses for all programmes. I suppose it's a bit like a keylogger.

This is only a personal thing, so I don't care about making it work on Windows/OSX, and I don't care about when people have fancy remote X sessions etc.


Solution

  • Take a look at what others have done already. You can take a look on how this pykeylogger code handles Linux in its backend, and see if that works for you.
