Re: [g-a-devel] AccessibleDeviceEventMask and SPI_registerDeviceEventListener()

[Willie Walker <William Walker Sun COM>]

Hi Jeff an everyone:

The AT-SPI/D-Bus work is being tracked at 
http://www.linuxfoundation.org/en/Accessibility/ATK/AT-SPI/AT-SPI_on_D-Bus, 
and it includes a plan to migrate CSPI to D-Bus.

IMO, doing this work in Python is a lot easier than doing it in C, so 
that's why we're seeing more and more projects on the assistive 
technology and testing side moving from the C bindings to the Python 
bindings.

Hope this helps,

Will
