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.
