wxruby users - Jan 2009 - Creating a Progress Bar

All,
 
I am attempting to add a progress bar to my application.  What is prompting the
progress bar to be displayed is the pressing of a button.  This button performs
an action, and for the sake of an example, lets say that it is printing one
million words to the screen.  While these words are printing to the screen, I
want a progress bar to be running.  I want the bar to fill completely, then go
blank, and fill completely over and over again until all of the words are
printed to the screen.  Once all of the words are printed, I want the progress
bar to stop its routine. I have the progress bar up and running, but my problem
is that I am using a while loop to continuously fill the bar, so in turn it is
running infinitely, and the code that comes after it, the words printing, is
never being executed.  I can elaborate if necessary.  Thanks in advance for all
of your assistance.

I guess you mean ProgressDialog or Gauge. They will both do roughly the 
same thing, but the former will display it in a standalone
dialog.

Use the ''maximum'' argument of ProgressDialog to set how many
steps there
are to progress through. In your case, it might be the number of words.  
Use the #update method to set how many steps have been completed. The 
dialog is automatically dismissed when the full number of steps is 
finished, or call #close to finish it early.

It works the same with Gauge, except you use #value= to set how many 
steps have been done.

Well, don''t use an infinite while loop... either call break somewhere
in
the loop to exit it, or use an ''each'' loop over the right 
number of items.

If that''s not it, perhaps describe your question more clearly, and if 
possible show a little sample of code that you''re working on.
