Hi,
Below is a question from Jan Martinek sent back in 2006. I am trying
to do the same thing, I haven't found anywhere on the web how to do
it.
The summary is I want to catch all mouse and/or keyboard events
anywhere on the screen? I tried what Jan did except assigned w with
w = gtk.gdk.get_default_root_window()
This will return a gtk.gdk.Window, not a gtk.Window as in the example
you posted.
http://library.gnome.org/devel/pygtk/stable/class-gdkwindow.html#function-gdk--get-default-root-window
which worked fine, but the
w.connect('motion-notify-event', wakeup)
failed with a message along the lines of 'for gtk.gdk.Window unknown
signal motion-notify-event' (sorry can't remember the exact message,
and i'm away from my desktop).
A gtk.gdk.Window doesn't have this signal, check the docs for info:
http://library.gnome.org/devel/pygtk/stable/class-gdkwindow.html
Maybe this post will help you a bit:

Cheers,

I can't find what signals are valid for a gtk.gdk.Window. And even if
I could, I still need it to with the 'motion-notify-event'.
Thanks for any clues!

Hello,
please, does anyone know how to catch all keyboard and mouse events
regardless of main window state? If I try this
#!/usr/bin/env python
import gtk
def wakeup(widget, event):
print"Event number %d woke me up" % event.type
w = gtk.Window()
w.add_events(gtk.gdk.KEY_PRESS_MASK |
gtk.gdk.POINTER_MOTION_MASK |
gtk.gdk.BUTTON_PRESS_MASK |
gtk.gdk.SCROLL_MASK)
w.connect("motion-notify-event", wakeup)
w.connect("key-press-event", wakeup)
w.connect("button-press-event", wakeup)
w.connect("scroll-event", wakeup)
w.show()
gtk.main()
then it responds to keypresses only if the window is active. Mouse events
are catched only when the cursor is placed within the window.
How can I catch all the events even when the window is
inactive/minimalized/hidden? Do you know any application that must be able
to do this? For example
- applets measuring distance travelled by mouse cursor
- typing-break applications that notify the user that he typed for a long
period of time a should have a rest.
- something that monitors user's activity/inactivity (various IM clients?)
- "xeyes" - eyes that always look at the mouse cursor
- keyloggers - malicious programs (if there are any) sniffing keystrokes
(mainly passwords) and logging them into a file.
- ???
I am looking for something written in pure GTK (no direct xlib calls) so
that I could learn from the source code.
Thank you
Jan Martinek
