DESCRIPTION
The iwidgets::::spinner command creates a spinner widget. The spinner is
comprised of an entryfield plus up and down arrow buttons. Arrows may
be drawn horizontally or vertically.
METHODS
The iwidgets::::spinner 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 spinner widgets:
ASOCIATED METHODS
delete get icursor index
insert scan selection xview
See the "entry" manual entry for details on the associated methods.
INHERITED METHODS
childsite clear peek
See the "entryfield" manual entry for details on the associated meth-
ods.
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 iwid-
gets::::spinner command.
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 avail-
able options for pathName (see TkConfigureInfo 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::::spinner command.
pathName down
Derived classes may overload this method to specialize function-
ality.
pathName up
Derived classes may overload this method to specialize function-
ality.
