[DUG] Animated progress "Throbber"

[John Bird]

Is there any Delphi equivalent of a "throbber"?   This is used when showing 
progress when the total length if a task in progress is not known so its 
useful to show something is happening. and is usually a small animated icon.

Would be nice to have such a component to place on a foirm.

Used a lot outside of Delphi - Examples are

-IE7 when page loading - the animated rotating circle whown on a tab header 
while a page is loading, and gets replaced with the sites icon when done.
-Firefox similar
-Vista gives a progress bar with the highlight swishing along it but not 
changing length of the progress bar, also the animated circle mouse cursor.
-Older versions of IE used to have an animated flag that waved while a page 
was loading - remember?

(This visual component is called a throbber in browser circles).

If I know the length then I can use a ProgressBar, but one does not 
always...and the Vista progress bar only shows on Vista of course.
