Sets the <code>indeterminate</code> property of the progress bar,
which determines whether the progress bar is in determinate
or indeterminate mode.
<p>
An indeterminate progress bar continuously displays animation
indicating that an operation of unknown length is occurring.
By default, this property is <code>false</code>.
Some look and feels might not support indeterminate progress bars;
they will ignore this property.
