/* Mouse Scroll Events: Line Scrolling, Pixel Scrolling and Common Event Flows
|
|
*
|
|
* There are two common event flows:
|
|
* (1) Normal line scrolling:
|
|
* 1. An NS_MOUSE_SCROLL event without kHasPixels is dispatched to Gecko.
|
|
* 2. A DOMMouseScroll event is sent into the DOM.
|
|
* 3. A MozMousePixelScroll event is sent into the DOM.
|
|
* 4. If neither event has been consumed, the default handling of the
|
|
* NS_MOUSE_SCROLL event is executed.
|
|
*
|
|
* (2) Pixel scrolling:
|
|
* 1. An NS_MOUSE_SCROLL event with kHasPixels is dispatched to Gecko.
|
|
* 2. A DOMMouseScroll event is sent into the DOM.
|
|
* 3. No scrolling takes place in the default handler.
|
|
* 4. An NS_MOUSE_PIXEL_SCROLL event is dispatched to Gecko.
|
|
* 5. A MozMousePixelScroll event is sent into the DOM.
|
|
* 6. If neither the NS_MOUSE_PIXELSCROLL event nor the preceding
|
|
* NS_MOUSE_SCROLL event have been consumed, the default handler scrolls.
|
|
* 7. Steps 4.-6. are repeated for every pixel scroll that belongs to
|
|
* the announced line scroll. Once enough pixels have been sent to
|
|
* complete a line, a new NS_MOUSE_SCROLL event is sent (goto step 1.).
|
|
*
|
|
* If a DOMMouseScroll event has been preventDefaulted, the associated
|
|
* following MozMousePixelScroll events are still sent - they just don't result
|
|
* in any scrolling (their default handler isn't executed).
|
|
*
|
|
* How many pixel scrolls make up one line scroll is decided in the widget layer
|
|
* where the NS_MOUSE(_PIXEL)_SCROLL events are created.
|
|
*
|
|
* This event flow model satisfies several requirements:
|
|
* - DOMMouseScroll handlers don't need to be aware of the existence of pixel
|
|
* scrolling.
|
|
* - preventDefault on a DOMMouseScroll event results in no scrolling.
|
|
* - DOMMouseScroll events aren't polluted with a kHasPixels flag.
|
|
* - You can make use of pixel scroll DOM events (MozMousePixelScroll).
