The iwidgets::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.








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:






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.









  

  
Returns the current value of the configuration option given by
      option. Option may have any of the values accepted by the
      iwidgets::scrolledcanvas command.

  

  
Returns the child site widget path name.

  

  
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 iwidgets::scrolledcanvas command.

  

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