-
- // Of Mice and Men
- // ---------------
- //
- // There are three types of scroll data available on a scroll wheel CGEvent.
- // Apple's documentation ([1]) is rather vague in their differences, and not
- // terribly helpful in deciding which to use. This is what's really going on.
- //
- // First, these events behave very differently depending on whether a standard
- // wheel mouse is used (one that scrolls in discrete units) or a
- // trackpad/Mighty Mouse is used (which both provide continuous scrolling).
- // You must check to see which was used for the event by testing the
- // kCGScrollWheelEventIsContinuous field.
- //
- // Second, these events refer to "axes". Axis 1 is the y-axis, and axis 2 is
- // the x-axis.
- //
- // Third, there is a concept of mouse acceleration. Scrolling the same amount
- // of physical distance will give you different results logically depending on
- // whether you scrolled a little at a time or in one continuous motion. Some
- // fields account for this while others do not.
- //
- // Fourth, for trackpads there is a concept of chunkiness. When scrolling
- // continuously, events can be delivered in chunks. That is to say, lots of
- // scroll events with delta 0 will be delivered, and every so often an event
- // with a non-zero delta will be delivered, containing the accumulated deltas
- // from all the intermediate moves. [2]
- //
- // For notchy wheel mice (kCGScrollWheelEventIsContinuous == 0)
- // ------------------------------------------------------------
- //
- // kCGScrollWheelEventDeltaAxis*
- // This is the rawest of raw events. For each mouse notch you get a value of
- // +1/-1. This does not take acceleration into account and thus is less
- // useful for building UIs.
- //
- // kCGScrollWheelEventPointDeltaAxis*
- // This is smarter. In general, for each mouse notch you get a value of
- // +1/-1, but this _does_ take acceleration into account, so you will get
- // larger values on longer scrolls. This field would be ideal for building
- // UIs except for one nasty bug: when the shift key is pressed, this set of
- // fields fails to move the value into the axis2 field (the other two types
- // of data do). This wouldn't be so bad except for the fact that while the
- // number of axes is used in the creation of a CGScrollWheelEvent, there is
- // no way to get that information out of the event once created.
- //
- // kCGScrollWheelEventFixedPtDeltaAxis*
- // This is a fixed value, and for each mouse notch you get a value of
- // +0.1/-0.1 (but, like above, scaled appropriately for acceleration). This
- // value takes acceleration into account, and in fact is identical to the
- // results you get from -[NSEvent delta*]. (That is, if you linked on Tiger
- // or greater; see [2] for details.)
- //
- // A note about continuous devices
- // -------------------------------
- //
- // There are two devices that provide continuous scrolling events (trackpads
- // and Mighty Mouses) and they behave rather differently. The Mighty Mouse
- // behaves a lot like a regular mouse. There is no chunking, and the
- // FixedPtDelta values are the PointDelta values multiplied by 0.1. With the
- // trackpad, though, there is chunking. While the FixedPtDelta values are
- // reasonable (they occur about every fifth event but have values five times
- // larger than usual) the Delta values are unreasonable. They don't appear to
- // accumulate properly.
- //
- // For continuous devices (kCGScrollWheelEventIsContinuous != 0)
- // -------------------------------------------------------------
- //
- // kCGScrollWheelEventDeltaAxis*
- // This provides values with no acceleration. With a trackpad, these values
- // are chunked but each non-zero value does not appear to be cumulative.
- // This seems to be a bug.
- //
- // kCGScrollWheelEventPointDeltaAxis*
- // This provides values with acceleration. With a trackpad, these values are
- // not chunked and are highly accurate.
- //
- // kCGScrollWheelEventFixedPtDeltaAxis*
- // This provides values with acceleration. With a trackpad, these values are
- // chunked but unlike Delta events are properly cumulative.
- //
- // Summary
- // -------
- //
- // In general the best approach to take is: determine if the event is
- // continuous. If it is not, then use the FixedPtDelta events (or just stick
- // with Cocoa events). They provide both acceleration and proper horizontal
- // scrolling. If the event is continuous, then doing pixel scrolling with the
- // PointDelta is the way to go. In general, avoid the Delta events. They're
- // the oldest (dating back to 10.4, before CGEvents were public) but they lack
- // acceleration and precision, making them useful only in specific edge cases.
