Hi,
is there a way to get mouseDragged: events for an NSView more
frequently? I'm implementing drawing tools, and my brush drawings
look more like Polygons. I vaguely remember that someone had this
problem before on the list, but I just can't find the messages in the
archives anymore. Here's what I have tried so far:
1) Optimized my drawing code so it honors and invalidates only the
rects that actually changed, thinking my drawing was taking too long.
2) Registered a tracking region for my NSView. Zilch improvement.
3) Changed my code to call NSApp's getNextEvent: in a tight loop in
NSTrackingRunloopMode, processing only mouseDragged and mouseUp
events. Didn't improve anything either.
Should one of these have done it? Has anyone got this working and can
tell me what worked for them? Any sample code anywhere so I can check
where I went wrong?
And if nobody has a clue, anyone know where among Apple's Dev Tools I
can find a simple, usable profiler that just runs my app and tells me
how much time it spent on average, longest and shortest in a certain
method, or in a function called from it? I don't need anything nifty,
just something like good ol' Metrowerks Profiler...
