Weird; I don’t think I’ve seen non-integer mouse coords before. Does your view have a scale transformation on it? > 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. You might need to truncate the moved/dragged coords too, then, just for consistency. I don’t think the OS tracks the mouse position at a resolution higher than screen pixels anyway. —Jens_______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
