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:

ASSOCIATED 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 methods.

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.

COMPONENTS

Name:	downarrow
Class:	Canvas

    The downarrow component is the downward pointing button of the spinner. See the "canvas" widget manual entry for details on the downarrow component item.

Name:	uparrow
Class:	Canvas

    The uparrow component is the upward pointing button of the spinner. See the "canvas" widget manual entry for details on the uparrow component item.

EXAMPLE

 }
 proc spinMonth {step} {
     global months
     set index [expr [lsearch $months [.sm get]] + $step]
     if {$index < 0} {set index 11}
     if {$index > 11} {set index 0}
     .sm delete 0 end
     .sm insert 0 [lindex $months $index]
