ttk::radiobutton - Mutually exclusive option widget

SYNOPSIS

ttk::radiobutton pathName ?options?

---

DESCRIPTION

ttk::radiobutton widgets are used in groups to show or change a set of mutually-exclusive options. Radiobuttons are linked to a Tcl variable, and have an associated value; when a radiobutton is clicked, it sets the variable to its associated value.

STANDARD OPTIONS

 
 -class     -compound-cursor
 -image     -state-style
 -takefocus -text-textvariable
 -underline -width
 
 

See the ttk_widget manual entry for details on the standard options.

WIDGET-SPECIFIC OPTIONS

 
 Command-Line Name:-command
 Database Name:command
 Database Class:Command
 

A Tcl script to evaluate whenever the widget is invoked.

 
 Command-Line Name:-value
 Database Name:Value
 Database Class:Value
 

The value to store in the associated -variable when the widget is selected.

 
 Command-Line Name:-variable
 Database Name:variable
 Database Class:Variable
 

The name of a global variable whose value is linked to the widget. Default value is ::selectedButton.

WIDGET COMMAND

In addition to the standard cget, configure, identify, instate, and state commands, radiobuttons support the following additional widget commands:

pathname invoke

Sets the -variable to the -value, selects the widget, and evaluates the associated -command. Returns the result of the -command, or the empty string if no -command is specified.

WIDGET STATES

The widget does not respond to user input if the disabled state is set. The widget sets the selected state whenever the linked -variable is set to the widget's -value, and clears it otherwise. The widget sets the alternate state whenever the linked -variable is unset. (The alternate state may be used to indicate a ``tri-state'' or ``indeterminate'' selection.)
