<DT><STRONG><A NAME="item_%2Dwidth">-width</A></STRONG><BR>
<DD>
Specifies the desired narrow dimension of the ProgressBar in screen units (i.e.
any of the forms acceptable to Tk_GetPixels). For vertical ProgressBars this is
the ProgressBars width; for horizontal bars this is the ProgressBars height.
<P></P>
<DT><STRONG><A NAME="item_%2Dlength">-length</A></STRONG><BR>
<DD>
Specifies the desired long dimension of the ProgressBar in screen units (i.e. any
of the forms acceptable to Tk_GetPixels). For vertical ProgressBars this is the
ProgressBars height; for horizontal scales it is the ProgressBars width.
<P></P>

<DD>
<DT><STRONG><A NAME="item_%2Dblocks">-blocks</A></STRONG><BR>
<DD>
<DT><STRONG><A NAME="item_%2Dresolution">-resolution</A></STRONG><BR>
<DD>
A real value specifying the resolution for the scale. If this value is greater
than zero then the scale's value will always be rounded to an even multiple of
this value, as will tick marks and the endpoints of the scale. If the value is
less than zero then no rounding occurs. Defaults to 1 (i.e., the value will be
integral).
<P></P>
<DT><STRONG><A NAME="item_%2Danchor">-anchor</A></STRONG><BR>
<DD>
<DT><STRONG><A NAME="item_%2Dvariable">-variable</A></STRONG><BR>
<DD>
Specifies the reference to a scalar variable to link to the ProgressBar.
Whenever the value of the variable changes, the ProgressBar will upate
to reflect this value. (See also the <STRONG>value</STRONG> method below.)

If <EM>value</EM> is omitted, returns the current value of the ProgressBar. If
<EM>value</EM> is given, the value of the ProgressBar is set. If <EM>$value</EM> is
given but undefined the value of the option <STRONG>-from</STRONG> is used.
