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.

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

- 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 iwidgets::scrolledcanvas command.
