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


METHODS
       The  iwidgets::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:

ASSOCIATED METHODS
       addtag          bbox           bind            canvasx
       canvasy         coords         create          dchars
       delete          dtag           find            focus
       gettags         icursor        index           insert
       itemconfigure   lower          move            postscript
       raise           scale          scan            select
       type            xview          yview

       See the "canvas" manual entry for details on the associated methods.


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 iwidgets::scrolledcanvas 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 informa-tion information
              tion 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 correspond-ing corresponding
              ing 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  val-ues values
              ues accepted by the iwidgets::scrolledcanvas command.

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