NEWT-MouseEvent getWheelRotation() API Update - Fixes Bug 659: NEWT Horizontal Scrolling Behavior (OSX, X11, Win32); Bug 639: High-Res Mouse-Wheel
- API update 'float getWheelRotation()':
Usually a wheel rotation of > 0.0f is up, and < 0.0f is down.
Usually a wheel rotations is considered a vertical scroll.
If isShiftDown(), a wheel rotations is considered a horizontal scroll,
where shift-up = left = > 0.0f, and shift-down = right = < 0.0f.
However, on some OS this might be flipped due to the OS default behavior.
The latter is true for OS X 10.7 (Lion) for example.
The events will be send usually in steps of one, ie. -1.0f and 1.0f.
Higher values may result due to fast scrolling.
Fractional values may result due to slow scrolling with high resolution devices.
The button number refers to the wheel number.
- Fix Bug 659: NEWT Horizontal Scrolling Behavior (OSX, X11, Win32)
- See new API doc above
- X11/Horiz: Keep using button1 and set SHIFT modifier
- OSX/Horiz:
- PAD: Use highes absolute scrolling value (Axis1/Axis2)
and set SHIFT modifier for horizontal scrolling (Axis2)
- XXX: Use deltaX for horizontal scrolling, detected by SHIFT modifier. (traditional)
- Windows/Horiz:
- Add WM_MOUSEHWHEEL support (-> set SHIFT modifier), but it's rarely impl. for trackpads!
- Add exp. WM_HSCROLL, but it will only be delivered if windows has WS_HSCROLL, hence dead code!
- Android:
- Add ACTION_SCROLL (API Level 12), only used if layout is a scroll layout
- Using GestureDetector to detect scroll even w/ pointerCount > 2, while:
- skipping 1st scroll event (value too high)
- skipping other events while in-scroll mode
- waiting until all pointers were released before cont. normally
- using View config's 1/touchSlope as scale factor
- Fix Bug 639: High-Res Mouse-Wheel
- getWheelRotation() return value changed: int -> float
allowing fractions, see API doc changes above.
- Fractions are currently supported natively (API) on
- Windows
- OSX
- Android
- AndroidNewtEventFactory ir refactored (requires an instance now) and
AndroidNewtEventTranslator (event listener) is pulled our of Android WindowDriver.
