Re: Proposal: enable accessibility by default for GNOME

Wow - that polling really does bite. :-( Looks like it's been in there for 6 years!

To me, it kind of seems rather inefficient for the prototypical use case of mouse motion events, which is to drive the region of interest for the magnifier. I logged a bug/rfe a while ago and to just have gnome-mag track the mouse directly rather than require two CORBA actions per mouse movement (one from the bridge to Orca and one from Orca to the magnifier): I haven't had time to create a patch, and the current maintainer is only doing so very sporadically due to time constraints.

Regardless of making modifications such as those requested in bug #522967, I wonder if we can make modifications to the bridge to only do the polling if someone has requested to be notified of the events?

Here is one datapoint:
