# Abstract
This TIP proposes changing the look of the Tk checkbutton and
radiobutton widgets on Unix to more closely match the Windows
counterparts.
# Rationale
The current visual aspect of the Unix version checkbutton and
radiobutton has proved to be confusing to users. The distinction
between selected \(On\) and unselected \(Off\) states are not visually
different enough to clearly identify one from another. Indeed, in the
rare case where only one checkbutton is present, one cannot tell for
certain if the state is On or Off. With a check or dot mark icon
\(dependent on the type of widget\) displayed in the Windows version,
there is no question about the state of the widget.
# Proposed Changes
The checkbutton shall \(when the indicator is turned on\) display an
check-mark or other distinguishing icon/symbol that clearly indicates
an On state. The Off state will be displayed with an empty box. The
state values will _not_ be indicated by changing relief or
background color.
The radiobutton shall \(when the indicator is turned on\) display an dot
mark or other distinguishing icon/symbol that clearly indicates a
selected or On state. The unselected or Off state shall be displayed
with an empty diamond. The state values will _not_ be indicated by
changing relief or background color.
