super: UITextView (on iOS)
The TextView class implements the behavior for a scrollable, multiline text region. The class supports the display of text using custom style information and also supports text editing. You typically use a text view to display multiple lines of text, such as when displaying the body of a large text document.
Load() This event is called when the object becames available in the current runtime system.
DidBeginEditing() Use this event to be notified when editing began in the specified text field.
DidEndEditing() Use this event to be notified when editing stopped for the specified text field.
Changed() Use this event to be notified when text changed in the specified text field.
DidChangeSelection() Use this event to be notified when text selection changed in the specified text field.
DidScroll() This event is called when the user scrolls the content view.
DidEndDragging(decelerate: Bool) This event is called when dragging ended in the scroll view. The scroll view sends this event when the user’s finger touches up after dragging content. The decelerating property of the scroll view controls deceleration. The decelerate value is true if the scrolling movement will continue, but decelerate, after a touch-up gesture during a dragging operation. If the value is NO, scrolling stops immediately upon touch-up.
DidEndDecelerating() This event is called when the scroll view ends decelerating the scrolling movement.
Unload() This event is called when the object has been removed from the current runtime system (but not yet deallocated).
