## DESCRIPTION

The **iwidgets::radiobox** command creates a radio button box widget  capable of adding, inserting, deleting, selecting, and configuring  radiobuttons as well as obtaining the currently selected button.

## METHODS

The **iwidgets::radiobox** 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 *arg*s determine the exact behavior of the command.

Many of the widget commands for the **radiobox** take as one argument an indicator of which radiobutton of the radiobox to operate on.  These indicators are called *indexes* and allow reference and manipulation of radiobuttons. Radiobox indexes may be specified in any of the following forms:

- *number*

  Specifies the radiobutton numerically, where 0 corresponds to the top  radiobutton of the radiobox.

- **end**

  Indicates the last radiobutton of the radiobox.

- *pattern*

  If the index doesn't satisfy one of the above forms then this form is used.  *Pattern* is pattern-matched against the tag of each radiobutton in the radiobox, in order from top to bottom, until a matching entry is found.  The rules of **Tcl\_StringMatch** are used.

## WIDGET-SPECIFIC METHODS

- *pathName* **add** *tag* ?*option value option value*?

  Adds a new radiobutton to the radiobuttond window on the bottom.  The command takes additional options which are passed on to the radiobutton as construction arguments.  These include the standard Tk radiobutton options.  The tag is returned.

- *pathName* **buttonconfigure** *index* ?*options*?

  This command is similar to the **configure** command, except that it applies to the options for an individual radiobutton,  whereas **configure**applies to the options for the radiobox as a whole. *Options* may have any of the values accepted by the **add** widget command.  If *options* are specified, options are modified as indicated in the command and the command returns an empty string. If no *options* are specified, returns a list describing the current options for entry *index* (see **Tk\_ConfigureInfo** for information on the format of this list).

- *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::radiobox** 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::radiobox** command.

- *pathName* **delete** *index*

  Deletes a specified radiobutton given an *index*.

- *pathName* **deselect** *index*

  Deselects a specified radiobutton given an *index*.

- *pathName* **flash** *index*

  Flashes a specified radiobutton given an *index*.

- *pathName* **get**

  Returns the tag of the currently selected radiobutton.

- *pathName* **index** *index*

  Returns the numerical index corresponding to index.

- *pathName* **insert** *index* *tag* ?*option value option value ...*?

  Same as the **add** command except that it inserts the new radiobutton just before the one given by *index*, instead of appending to the end of the radiobox.  The *option*, and *value* arguments have the same interpretation as for the **add** widget command.

- *pathName* **select** *index*

  Selects a specified radiobutton given an *index*.
