<DD>
If this option is specified, then the true contents of the entry are not displayed in the
window. Instead, each character in the entry's value will be displayed as the first character
in the value of this option, such as ``*''. This is useful, for example, if the entry is to
be used to enter a password. If characters in the entry are selected and copied elsewhere, the
information copied will be what is displayed, not the true contents of the entry.
</DD>
</DL>
<DL><DT><A NAME="-state"><B>-state</B></A></DT>
<DD>
Specifies one of two states for the Entry: <B>normal</B> or <B>disabled</B>.
In normal state the text of the Entry is displayed using the <B>foreground</B> option.
In disabled state the text of the Entry is displayed using the <B>disabledforeground</B>
option. If the entry is disabled then the value may not be changed by user input
and no insertion cursor will be displayed, even if the input focus is in the widget.
Disabled state is the same as not editable with visual effect.
</DD>
</DL>
<DL><DT><A NAME="-width"><B>-width</B></A></DT>
<DD>
Specifies an integer value indicating the desired width of the entry window, in average-size
characters of the widget's font. If the value is less than or equal to zero, the widget picks

describing the one named <I>option</I> (this list will be identical to the corresponding
sublist of the value returned if no <I>option</I> is specified). If one or
more <I>option-value</I> pairs are specified, then the command modifies the given widget
option(s) to have the given value(s); in this case the command returns an empty string.
<I>Option</I> may have any of the values accepted by the creation command.
Read-only options are not be modified.
