Greetings-
This seemed like the most appropriate place to post. Some background:
We have a carbon application that has a need to receive on a system-wide
basis: Mouse moved and mouse down events.
Using the carbon APIs is no good; hooking an event handler to receive
mouse moved events fails when a) the mouse is down in a control and
b) when your app. is in the background.
It is even worse to globally receive the state of the button, in both
cases you have to resort to polling and for mouse down events you
have to make sure your frequency of polling is 2x the speed of a
fast user click or you miss clicks.
Can we solve this problem by writing some sort of 'kext' (or something!)
that globally hooks event processing and lets our application have a
path to receive this information?
TIA for any suggestions, advice, pointers to same.
