Mutually exclusive option widget
ttk::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.
|Name||Database name||Database class|
|A Tcl script to evaluate whenever the widget is invoked.|
|The value to store in the associated -variable when the widget is selected.|
|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:
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.)
Ttk::radiobutton widgets support the Toolbutton style in all standard themes, which is useful for creating widgets for toolbars.
