Anybody know how to determine the current mouse buttons state ? I need
to determine at some random interval wether the left mouse button is
down or up.
(I know [NSEvent mouseLocation] will give the current mouse location)
It is a deprecated function but
(BOOL) Button()
returns the state of the left (or, strangely enough, the middle) mouse
button.
It is a Carbon function so you must include the Carbon framework in
Frameworks.Linked Frameworks (where Cocoa.framework is).
NOOOOOOOOOO!!!
You don't want to do that. Unfortunately I don't know the correct API
to use, but one thing that has stuck in my mind from a few WWDCs is a
really simple demo of how not to poll for events. Basically, Button()
is a very old API that predates multitasking, and it will hog the event
loop like nothing else, stopping anything else from getting done.
Check the docs on Button() at
http://developer.apple.com/documentation/Carbon/Reference/
EventManagerLegacyRef/index.html
for alternatives.
Cheers,
Richard
