At one point, my application blocks the runloop and I have to poll
for mouse events by calling [NSApplication
nextEventMatchingMask:untilDate:inMode:dequeue:]. I'm not happy with
the polling. It seems to me that creating a separate thread and
configuring its runloop to process the events I'm interested in
(specific mouse events for a specific window) is a more elegant
solution. I couldn't find any example code doing that. I suspect
that it's not possible for third-party developers to tap into the
event stream coming from the window server, to create a
CFRunloopSource similar to the one that feeds the main runloop.
You can't really do that, because the GUI should always be driven
from the main thread. Few parts of the GUI are thread-safe. Why do you
have to block the runloop anyway? Have you thought about doing your
work asynchronously or even in a second thread, and only doing the
actual event handling and redraws in the main thread?
PS - please do not reply to existing threads and change the subject
line to create a new posting. That will sort your message under that
old, completely unrelated thread in threaded view in most mail
applications. Create a new message instead.
