NAME

       autoscroll - Provides for a scrollbar to automatically mapped and unmapped as needed

SYNOPSIS

       package require Tcl

       package require autoscroll  ?1.1?

       ::autoscroll::autoscroll scrollbar

       ::autoscroll::unautoscroll scrollbar

       ::autoscroll::wrap

       ::autoscroll::unwrap

_________________________________________________________________

DESCRIPTION

       This package allows scrollbars to be mapped and unmapped as needed depending on the size and content of the scrollbars scrolled widget. The
       scrollbar must be managed by either pack or grid, other geometry managers are not supported.

       When managed by pack, any geometry changes made in the scrollbars parent between the time a scrollbar is unmapped, and when  it	is  mapped
       will  be  lost. It is an error to destroy any of the scrollbars siblings while the scrollbar is unmapped. When managed by grid, if anything
       becomes gridded in the same row and column the scrollbar occupied it will be replaced by the scrollbar when remapped.

       This package may be used on any scrollbar-like widget as long as it supports the set subcommand in the same style as scrollbar. If the  set
       subcommand is not used then this package will have no effect.

       ::autoscroll::autoscroll scrollbar
	      Arranges for the already existing scrollbar scrollbar to be mapped and unmapped as needed.

       ::autoscroll::unautoscroll scrollbar
	      Returns the named scrollbar to its original static state.

       ::autoscroll::wrap
	      Arranges for all scrollbars created after this command is run to be automatically mapped and unmapped as needed.

       ::autoscroll::unwrap
	      Turns off the automatic autoscrolling of all new scrollbars.  Does not effect existing scrollbars

       text .t -yscrollcommand ".scrolly set"
       scrollbar .scrolly -orient v -command ".t yview"
       pack .scrolly -side right -fill y
       pack .t -side left -fill both -expand 1
       ::autoscroll::autoscroll .scrolly

NAME

       Tk::Scrolled - Create a widget with attached scrollbar(s)

SYNOPSIS

	   $whatever = $parent->Scrolled(Whatever ?,-scrollbars=>where? ?,...?);

DESCRIPTION

       To stop a flood of ScrlWhatever widgets Perl/Tk introcuded the special constructor Scrolled.  Scrolled creates a widget of the given Class
       Whatever with attached scrollbar(s).

OPTIONS

       All options beside -scrollbars explained below are passed to the Whatever widget constructor.

       -scrollbars
	   Expects as argument the position where the scrollbars should be created:  w, e or n, s or a combination of them.  If the one or both
	   positions are prefixed with o the scrollbar will only show up if there is a 'real' need to scroll.

ADVERTISED SUBWIDGETS

       See "Subwidget" in Tk::mega how to use advertised widgets.

       scrolled
	   the scrolled widget

       widget
	   same as scrolled above.  widget is the kind of widget passed to scrolled as first argument in all lowercase.

       xscrollbar
	   the Scrollbar widget used for horizontal scrolling (if it exists)

       yscrollbar
	   the Scrollbar widget used for vertical scrolling (if it exists)

       corner
	   a frame in the corner between the vertical and horizontal scrolbar

BUGS

       If a widget does not support -{x,y}scrollcommand options, Scrolled does not complain if the specified widget class does not support them.
       E.g.,

	   $parent->Scrolled('Button', ...)

       One does not get an error message or warning when one tries to configure scrollbars after the widget construction:

	   $ascrolled->configure(-scrollbars => 'e');
