Specifies the relief for the checkbutton when the indicator is not drawn and the checkbutton is off. The default value is "raised". By setting this option to "flat" and setting #:indicatoron to false and #:overrelief to raised, the effect is achieved of having a flat button that raises on mouse-over and which is depressed when activated. This is the behavior typically exhibited by the Align-Left, Align-Right, and Center radiobuttons on the toolbar of a word-processor, for example.
