Hello I am reposting this from Moose mailing list, because it seems like problem in Pharo itself. In HandMorph>>#generateKeyboardEvent: is a condition based on charCode which tells whether incoming input event is of keyboard type or mousewheel type (code quoted below). On Linux, when I use mouse wheel, keyValue and charCode are both 30 or 31 respectively. But on Windows there is keyValue 30 or 31, but charCode 0. This condition is based on charCode being 30 or 31 so it absolutely never returns MouseWheelEvent. When I replace charCode with keyValue there, mouse wheel works fine (but I am not sure whether it might not break something else). Pharo core windows like System browser or Monticello seem to somehow get around it and work, but nothing else, like Roassal where I reported this bug before, so in whole Roassal mouse wheel does not work on Windows.

I checked this and I see that there is an error with:
HandMorph>>#generateKeyboardEvent:
in this piece of code:
(type = #keystroke and: [(buttons anyMask: 16) and: [*charCode *= 30 or: [*charCode *= 31]]]) ifTrue: [^MouseWheelEvent new setType: #mouseWheel position: lastMouseEvent cursorPoint direction: (charCode = 30 ifTrue: [#up] ifFalse: [#down]) buttons: buttons hand: self stamp: stamp].
The value for *charCode* is 0, that is the reason why MouseWheelEvent does not work in Roassal2 in Windows. Instead of MouseWheelEvent the KeyboardEvent is used.
*Note:* *keyvalue* has the value 31.
Maybe there is and error with Sensor class in Windows

We will have a look at it. This is important indeed.

Hello
RTZoomableView should enable zooming with mouse wheel. It works fine on Linux, not tested on Mac, but doesn't work for me on Windows (mouse
wheel
does nothing). For example, this one: RTRoassalExample new exampleScrollZoom
