<p>In manual mode, you are responsible for showing, updating (via <a href="output/Ext.ProgressBar.html#Ext.ProgressBar-updateProgress" ext:member="updateProgress" ext:cls="Ext.ProgressBar">updateProgress</a>) and clearing the
progress bar as needed from your own code.  This method is most appropriate when you want to show progress
throughout an operation that has predictable points of interest at which you can update the control.</p>
<p>In automatic mode, you simply call <a href="output/Ext.ProgressBar.html#Ext.ProgressBar-wait" ext:member="wait" ext:cls="Ext.ProgressBar">wait</a> and let the progress bar run indefinitely, only clearing it
once the operation is complete.  You can optionally have the progress bar wait for a specific amount of time
and then clear itself.  Automatic mode is most appropriate for timed operations or asynchronous operations in
