 Tk: radiobutton

• -value Specifies value to store in the button's associated variable whenever this button is selected.
• -text "something" Text to label the radiobutton
• -variable variable name Specifies name of global variable to set whenever this button is selected. Changes in this variable also cause the button to select or deselect itself. Defaults to the value selectedButton.
• -state Specifies one of three states for the radiobutton: normal, active, or disabled. In normal state the radiobutton is displayed using the foreground and background options. The active state is typically used when the pointer is over the radiobutton. In active state the radiobutton is displayed using the activeForeground and activeBackground options. Disabled state means that the radiobutton should be insensitive: the default bindings will refuse to activate the widget and will ignore mouse button presses. In this state the disabledForeground and background options determine how the radiobutton is displayed.
