A radiobutton is a widget that displays a textual string, bitmap or image and a diamond called an indicator. If text is displayed, it must all be in a single font, but it can occupy multiple lines on the screen (if it contains newlines) and one of the characters may optionally be underlined using the underline option. A radiobutton has all of the behaviour of a simple button: it can display itself in either of three different ways, according to the state option; it can be made to appear raised, sunken, or flat; and it invokes a Tk command whenever mouse button 1 is clicked over the check button.
In addition, radiobuttons can be selected. If a radiobutton is selected, the indicator is normally drawn with a sunken relief and a special colour, and a Tk variable associated with the radiobutton is set to a particular value. If the radiobutton is not selected, the indicator is drawn with a raised relief and no special colour. Typically, several radiobuttons share a single variable and the value of the variable indicates which radiobutton is to be selected. When a radiobutton is selected it sets the value of the variable to indicate that fact; each radiobutton also monitors the value of the variable and automatically selects and deselects itself when the variable's value changes. By default the variable selectedButton is used; its contents give the name of the button that is selected, or the empty string if no button associated with that variable is selected. The name of the variable for a radiobutton, plus the variable to be stored into it, may be modified with options on the command line. Configuration options may also be used to modify the way the indicator is displayed (or whether it is displayed at all). By default a radiobutton is configured to select itself on button clicks.

If the radiobutton's state is disabled then none of the above actions occur: the radiobutton is completely non-responsive.
The behaviour of radiobuttons can be changed by defining new bindings for individual widgets.
