Hi all,
Following up on a problem I was having a week or so back with receiving
multiple mouse-ups in an event loop, I've narrowed the problem down to the
events coming from a trackpad instead of a mouse.
Here's an odd thing:
NSUInteger mask = NSLeftMouseDownMask | NSLeftMouseUpMask |
NSLeftMouseDraggedMask | NSMouseMovedMask | NSScrollWheelMask | NSKeyDownMask;
while( loop )
{
theEvent = [NSApp nextEventMatchingMask:mask untilDate:[NSDate
distantFuture] inMode:NSEventTrackingRunLoopMode dequeue:YES];
This is the fragment of code that sets up the mask and grabs the event. I
should only get those events that match the mask, right? With a mouse, I do,
but with a trackpad I'm also getting right mouse down, right mouse dragged and
right mouse up returned. Is that expected? It seems incorrect.
I'm not sure it has a bearing on my bug because I do ignore those events, but
OTOH, the bug is only manifest using the trackpad. (Debugging this in the
debugger is impossible due to the dynamic nature of the loop, so I'm having to
try and log output at key points).
