DESCRIPTION

The 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 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 args 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 configureapplies 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 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 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.
