    The scrollutil::scrollarea mega-widget greatly simplifies the + creation of arbitrary scrolled widgets.  It consists of a scrollable + widget and two scrollbars connected with that widget.  The display mode + of each scrollbar can be static, dynamic, or none.  This scrolled window implementation also supports the widgets that are scrollable in one direction only (e.g., entry and ttk::entry) and respects the header component and title columns of What Is Scrollutil? Tcl 8.5) TclOO.  It is also free from the shimmering problem in connection with text widgets, which the above-mentioned - scrolled window implementations either share with the autoscroll package or - circumvent in a suboptimal way.

    The scrollutil::scrollsync mega-widget is designed for scrolling several - widgets simultaneously.  Whenever the horizontal/vertical position of - the view in the window of one of its widgets changes, the view in the windows - of all the other widgets is automatically adjusted accordingly, thus making - sure that the view's position in these windows is kept in sync.  This - mega-widget is horizontally and vertically scrollable, hence it can be - embedded into a scrollutil::scrollarea widget.

    From the point of view of the commands for mouse wheel event handling - provided by the Scrollutil package, the scrollability of a widget container - window means that the associated Tcl command supports the  xview - scroll number units  and  yview scroll - number units  subcommands.  The reason for requiring - at least Tk version 8.6b2 on Windows for these commands is that in earlier Tk - versions on this platform the mouse wheel events were sent to the widget - having the focus rather than to the one under the pointer.
