Hello,
There is a JavaFX Application [1] which has a rotated border which
contains a ScrollPane.
When the scroll pane is scrolled vertically by a mouse or by a touch pad
the scrollpane itself is scrolled horizontally.
What I see from the code the ScrollEvent constructor recomputes x and y
coordinates (actually the pickResult)
in the GestureEvent superclass [2] but leaves deltaX/Y as is [3].
Should deltaX/Y (and totalDeltaX/Y and may be textDeltaX/Y ) values be
recomputed in the similar way as x/y [4]?
It looks like it requires to compute and pass PickResult for deltaX/Y
to ScrollEvent as well.
