Re: Rolling my own ClutterInputDevice with python

[Thomas Schüßler <vindolin gmail com>]

Thanks, it turned out, I can do all those things intercepting all keyboard events with do_captured_event() then re-emitting the modified event with event.get_source().emit('key-press-event', modified_event).

The only thing I need to find out now is how to exclusively grab the keyboard device so that keys like ALT+F4 don't close the application.

Regards

Thomas

you cannot implement an InputDevice outside of Clutter, let alone in Python.

InputDevice instances are pure informational classes that reflect the
devices exposed by the windowing system input API.

if you have a device that appears as a keyboard then your windowing
system should expose it as a device, and Clutter can pick it up.

rummaging through the evdev file descriptor is not a great way to deal
with input.
