New in this Version 2.50
PropertySheet improvements were made, and the addition of granule refinement (still needs fine-tuning).
Version 2.40
Programatic changes in position related parameter are ignored during mouse operations. The mousewheel notification mechanism which was connected to the the same function dealing with setting the scroll position programatically simply didn't work because as we all know such kind of notification was blocked from day one the control started existing. It was by design. Now, the notification is unblocked, and sent like other change notifications.
(A) Users Additional Guide
Together with making the mousewheel functional, Keyboard control is likewise provided, either purely or in combination with the mousewheel.
When the mousewheel, is used alone, it changes position by the line (or singly). If the SHIFT key is pressed, it scans by the pagesize. On the other hand, if the CTRL key is pressed, it moves either to the absolute begining line or the farthest possible line reachable considering the indent.
When the keyboard is utilized purely, there are three keysets to consider: the arrow keys, the page keys, and the home and end keys.
Good Luck!
