WheelView

Written by Derez

List of types:

WheelView

WheelView creates a rotating wheel with list of text items.
The value that is at the center when the wheel stop can be read
by a Tick event sub, using ReadWheel method.
ScrollChanged(Position as int) event can be used
to get the scroll position, but it is not required
for the operation of the wheel.
The cover bitmap which gives the wheel its shape is attached and
should be put on a panel with the same size and place as the WheelView.
This is an 'Activity Object', it cannot be declared under Sub Process_Globals.

Events:

ScrollChanged(Position As Int)
Tick

Set Cyclic True if you want the wheel to be cyclic.
Wheelstep defines the height of each digit label.

Initialize2 (Wheelstep As Int, Values() As String, Cyclic As Boolean, EventName As String)

Initializes the WheelView with the set of values
as defined by the Values array.
Set Cyclic True if you want the wheel to be cyclic.
Wheelstep defines the height of each digit label.
