Is this only for Flex 3?

Kyle Hayes,

Yeah, I’m pretty sure this was added in Flex 3.

Hey Peter,

If you’ve ever played on Xbox Live and sent a voice message you’ll
notice that it’s a 10 second countdown indicated by a progress bar… I
want to accomplish the same thing.

I am recording Video to the FMS (VideoDisplay) and need to show the progress of the
record time (say max record time is 30 seconds) and when the progress
bar reaches it’s max (30 second duration), the video stops recording (just
like XBox live).

Secondly, when being played back, I need it to show the same progress…
from the beginning of the video to the end duration.

Would you happen to know how to use the ProgressBar in this way?

Peter, is their a property that speeds up the animation? I’m using the indeterminate animation for any process and sometimes they don’t take to long but the animation plays to slow to notice it.

Javier Julio,

I don’t see a property/style that easily allows that. The easiest way may be to set the indeterminateMoveInterval to something small like 20, or create a custom indeterminate skin for the Flex ProgressBar control which gives you the effect you want.
