DESCRIPTION

       The  scrolledcanvas  command creates a scrolled canvas with additional options to manage horizontal and vertical scrollbars.  This includes
       options to control which scrollbars are displayed and the method, i.e. statically or dynamically.

METHODS

       The scrolledcanvas command creates a new Tcl command whose name is pathName.  This command may be used to invoke various operations on  the
       widget.	It has the following general form: pathName option ?arg arg ...?  Option and the args determine the exact behavior of the command.
       The following commands are possible for scrolledcanvas widgets:

WIDGET-SPECIFIC METHODS
       pathName cget option
	      Returns the current value of the configuration option given by option.  Option may have any of the values accepted by the  scrolled-
	      canvas command.

       pathName childsite
	      Returns the child site widget path name.

       pathName configure ?option? ?value option value ...?
	      Query  or modify the configuration options of the widget.  If no option is specified, returns a list describing all of the available
	      options for pathName (see Tk_ConfigureInfo for information on the format of this list).  If option is specified with no value,  then
	      the  command  returns  a list describing the one named option (this list will be identical to the corresponding sublist of the value
	      returned if no option is specified).  If one or more option-value pairs are specified, then the command modifies	the  given  widget
	      option(s) to have the given value(s);  in this case the command returns an empty string.	Option may have any of the values accepted
	      by the scrolledcanvas command.

       pathName justify direction
	      Justifies the canvas contents via the scroll bars in one of four directions: left, right, top, or bottom.
