SYNOPSISttk::radiobutton pathName ?options?
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.
-class -compound-cursor -image -state-style -takefocus -text-textvariable -underline -width
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.
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.
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.)
