NAME

ttk::radiobutton — Mutually exclusive option widget

SYNOPSIS

ttk::radiobutton pathName ?options?

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.

STANDARD OPTIONS

-compound, compound, Compound
-cursor, cursor, Cursor
-image, image, Image
-state, state, State
-style, style, Style
-takefocus, takeFocus, TakeFocus
-text, text, Text

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.

STYLING OPTIONS

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.
