|

|

|
| - // 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
|

|
| - // 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
|

|
| - // 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.
