This is what we did in Record to remove extra buttons when a child hasn't moved the mouse in a while... (<a href="http://mediamods.com/public-svn/camera-activity/tags/54/ui.py">http://mediamods.com/public-svn/camera-activity/tags/54/ui.py</a>) But this has a very low sample rate:<br>

Does anyone know how to capture all mouse events? I am trying to get all<br>
mouse button up/down events, and maybe even all motion events. I have<br>
tried using gdk to listen to all events on the root window, but it doesn't<br>
seem to capture mouse events.<br>
<br>
It seems like the right way might be to use Xlib, or to hook into the<br>
window manager, or the X driver, or just listen to /dev/input/mouse0. I<br>
don't know much about any of these. What would you do?<br>
<br>
