Hi,
I'm using a NSTrackingArea in a view to receive mouseMoved events.
The cursor location in the mouseMoved and mouseDragged events have non-integer
coordinates (as expected).
e.g. x:140.601562 y:128.082031
However, the mouseDown and mouseUp events always produce truncated coordinates.
e.g. x:140.000000 y:128.000000
This causes inaccuracy with hit testing between mouseMoved and mouseDown.
All the mouse events use the same code to convert the point for the view :
NSPoint location = [self convertPoint:[theEvent locationInWindow]
fromView:nil];
Logged as e.g.
NSLog(@"moved x:%f y:%f", location.x, location.y);
What is the correct way to obtain coordinates that are consistent across all
the mouse events ?
Thanks.
