Synopsis

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.

-compound, compound, Compound

-cursor, cursor, Cursor

-image, image, Image

-state, state, State

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.)

Standard styles

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