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:

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 iwidgets::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 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::spinner command.

pathName down

Derived classes may overload this method to specialize functionality.

pathName up

Derived classes may overload this method to specialize functionality.
