Re: [AD] mouse callback

[aj <aj@xxxxxxxxxx>]

can i get some clarificatin on this:

Q. Does mouse_callback get called from a timer in an 'interupt' 
context,  that is to say from another thread other than the main thread my 
app is running in ?

i ask this because i need to time the mouse button clicks in order to 
measure when a double click has occurred.
How fast is this mouse timer running?    Will i get accurate(-ish) calls to 
my mouse_callback func  so i can time the double click speed.

If the mouse_callback is being called from another thread (other than the 
one my main app is running in)  i would require multi-threading locks if i 
need to
call functions in my main thread...    do i need to do this?
