the checkbutton is displayed using the \fBactiveForeground\fR and
\fBactiveBackground\fR options.  Disabled state means that the checkbutton
should be insensitive:  the default bindings will refuse to activate
the widget and will ignore mouse button presses.
In this state the \fBdisabledForeground\fR and
\fBbackground\fR options determine how the checkbutton is displayed.
.OP \-variable variable Variable
Specifies the name of a global variable to set to indicate whether
or not this button is selected.  Defaults to the name of the
button within its parent (i.e. the last element of the button
window's path name).
.OP \-width width Width
Specifies a desired width for the button.
If an image or bitmap is being displayed in the button then the value is in
screen units (i.e. any of the forms acceptable to \fBTk_GetPixels\fR);

The default is \fBunderline\fR.
.VS 8.4
.OP \-height height Height
Specifies the desired height for the window, in lines.
If zero or less, then the desired height for the window is made just
large enough to hold all the elements in the listbox.
.OP \-listvariable listVariable Variable
Specifies the name of a global variable.  The value of the variable is a list to
be displayed inside the widget; if the variable value changes then the
widget will automatically update itself to reflect the new value.  Attempts
to assign a variable with an invalid list value to \fB\-listvariable\fR
will cause an error.  Attempts to unset a variable in use as a
\fB\-listvariable\fR will fail but will not generate an error.
.OP \-selectmode selectMode SelectMode
Specifies one of several styles for manipulating the selection.

Available only for radiobutton entries.  Specifies the value to
store in the entry's associated variable when the entry is selected.
If an empty string is specified, then the \fB\-label\fR option
for the entry as the value to store in the variable.
.TP
\fB\-variable \fIvalue\fR
Available only for checkbutton and radiobutton entries.  Specifies
the name of a global variable to set when the entry is selected.
For checkbutton entries the variable is also set when the entry
is deselected.  For radiobutton entries, changing the variable
causes the currently-selected entry to deselect itself.
.LP
The \fBadd\fR widget command returns an empty string.
.RE
.TP

ignore the option entirely, so you can change its meaning if you
redefine the keyboard traversal scripts.
.OP \-text text Text
Specifies a string to be displayed inside the widget.  The way in which
the string is displayed depends on the particular widget and may be
determined by other options, such as \fBanchor\fR or \fBjustify\fR.
.OP \-textvariable textVariable Variable
Specifies the name of a global variable.  The value of the variable is a text
string to be displayed inside the widget;  if the variable value changes
then the widget will automatically update itself to reflect the new value.
The way in which the string is displayed in the widget depends on the
particular widget and may be determined by other options, such as
\fBanchor\fR or \fBjustify\fR.
.OP \-troughcolor troughColor Background
Specifies the color to use for the rectangular trough areas

the widget and will ignore mouse button presses.
In this state the \fBdisabledForeground\fR and
\fBbackground\fR options determine how the radiobutton is displayed.
.OP \-value value Value
Specifies value to store in the button's associated variable whenever
this button is selected.
.OP \-variable variable Variable
Specifies the name of a 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 \fBselectedButton\fR.
.OP \-width width Width
Specifies a desired width for the button.
If an image or bitmap is being displayed in the button, the value is in
screen units (i.e. any of the forms acceptable to \fBTk_GetPixels\fR);
