A Radiobutton Widget's Arguments

The radiobutton 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 radio-button widgets:

pathName :activate
Change the radio button's state to active and redisplay the button using its active foreground and background colors instead of normal colors. This command is ignored if the radio button's state is disabled. This command is obsolete and will eventually be removed; use "pathName :configure :state active" instead.
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 radiobutton command.
pathName :deactivate
Change the radio button's state to normal and redisplay the button using its normal foreground and background colors. This command is ignored if the radio button's state is disabled. This command is obsolete and will eventually be removed; use "pathName :configure :state normal" instead.
pathName :deselect
Deselect the radio button: redisplay it without a highlight in the selector and set the associated variable to an empty string. If this radio button was not currently selected, then the command has no effect.
pathName :flash
Flash the radio button. This is accomplished by redisplaying the radio button several times, alternating between active and normal colors. At the end of the flash the radio button is left in the same normal/active state as when the command was invoked. This command is ignored if the radio button's state is disabled.
pathName :invoke
Does just what would have happened if the user invoked the radio button with the mouse: select the button and invoke its associated Tcl command, if there is one. The return value is the return value from the Tcl command, or an empty string if there is no command associated with the radio button. This command is ignored if the radio button's state is disabled.
pathName :select
Select the radio button: display it with a highlighted selector and set the associated variable to the value corresponding to this widget.
