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.
