ttk::radiobutton - Mutually exclusive option widget
ttk::radiobutton pathName ?options?
radiobutton widgets are used in groups to show or change a set of mutu-ally-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.
- -compound -cursor-image
- -style -takefocus-text
- -underline -width
See the options manual entry for details on the standard options.
Database Name: command
Database Class: Command
A Tcl script to evaluate whenever the widget is invoked.
Database Name: Value
Database Class: Value
The value to store in the associated -variable when the widget is selected.
Database Name: variable
Database Class: Variable
The name of a global variable whose value is linked to the wid-get. Default value is ::selectedButton.
In addition to the standard cget, configure, instate, and state com-mands, radiobuttons support the following additional widget commands:
Sets the -variable to the -value, selects the widget, and evalu-ates the associated -command. Returns the result of the -com-mand, 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 widgetâ€™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 â€˜â€˜tri-stateâ€™â€™ or â€˜â€˜indeterminateâ€™â€™ selection.)
