<H2>DESCRIPTION</H2><PRE>
     The <STRONG>scrolledcanvas</STRONG> 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.
 
 
 
</PRE>
<H2>METHODS</H2><PRE>
     The <STRONG>scrolledcanvas</STRONG> command creates a new Tcl  command  whose
     name  is <EM>pathName</EM>.  This command may be used to invoke vari-
     ous operations on the widget.  It has the following  general
     form:
 
          <EM>pathName</EM> <EM>option</EM> ?<EM>arg</EM> <EM>arg</EM> ...?
 
     <EM>Option</EM> and the <EM>arg</EM>s determine the exact behavior of the com-
     mand.   The following commands are possible for scrolledcan-
     vas widgets:

</PRE>
<H2>WIDGET-SPECIFIC METHODS</H2><PRE>
     <EM>pathName</EM> <STRONG>cget</STRONG> <EM>option</EM>
          Returns the current value of the  configuration  option
          given  by  <EM>option</EM>.   <EM>Option</EM>  may have any of the values
          accepted by the <STRONG>scrolledcanvas</STRONG> command.
 
     <EM>pathName</EM> <STRONG>childsite</STRONG>
          Returns the child site widget path name.
 
     <EM>pathName</EM> <STRONG>configure</STRONG> ?<EM>option</EM>? ?<EM>value</EM> <EM>option</EM> <EM>value</EM> ...?
          Query  or  modify  the  configuration  options  of  the
          widget.   If  no  <EM>option</EM>  is  specified, returns a list
          describing all of the available  options  for  <EM>pathName</EM>
          (see  <STRONG>Tk_ConfigureInfo</STRONG> for information on the format of
          this list).  If <EM>option</EM> is specified with no <EM>value</EM>, then
          the  command  returns  a  list describing the one named
          option (this list will be identical to the  correspond-
          ing  sublist  of  the  value  returned  if no <EM>option</EM> is
          specified).  If one or more  <EM>option</EM> - <EM>value</EM>  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.  <EM>Option</EM> may have any
          of the values accepted by the <STRONG>scrolledcanvas</STRONG> command.
 
     <EM>pathName</EM> <STRONG>justify</STRONG> <EM>direction</EM>
          Justifies the canvas contents via the  scroll  bars  in
          one of four directions:  <STRONG>left</STRONG>, <STRONG>right</STRONG>, <STRONG>top</STRONG>, or <STRONG>bottom</STRONG>.
