ttk::radiobutton - 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.

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

See the ttk_widget manual entry for details on the standard 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.

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

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.)

Ttk::radiobutton widgets support the Toolbutton style in all standard themes, which is useful for creating widgets for toolbars.

The class name for a ttk::radiobutton is TRadiobutton.

Dynamic states: active, alternate, disabled, pressed, readonly, selected.

TRadiobutton styling options configurable with ttk::style are:

-background color
-compound compound
-foreground color
-indicatorbackground color
-indicatorcolor color
-indicatormargin padding
-indicatorrelief relief
-padding padding

Some options are only available for specific themes.

See the ttk::style manual page for information on how to configure ttk styles.
