- // 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. |
