Roassal2: RTZoomableView not working on Windows

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

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

Thanks for this finding. It seems like problem in Pharo itself, so I reposted this problem to Pharo-users mailing list.

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

Cheers,
Milton

Hi again

Problem has been on Windows VM side and has been fixed today. So since today's Windows VM (VM Windows 396 / 05.12.2014 08:29) mouse wheel works even on Windows.
