_________________________________________________________________
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.
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:
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.
pathName cget option
Returns the current value of the configuration option
given by option. Option may have any of the values
accepted by the 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 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.
