Too different to get into detail here. Have a close look at the component architecture of Halo (Flex 3). The lifecycle is quite different, take a look at createChildren and updateDisplayList. That's where you could use some of the code here. hth andy Deb,

But I need to do it in Flex3. Also I have to embed sound in this. Can you please help me out to solve the problem. I need to do something like this. But I need to do it in Flex3.

As for controls that scale larger over time involving scaling on rollovers-/outs, guess it's either a rounding problem or the upscale and downscale is not done properly - or the framework takes elements like border and the like inconsistently into account. One way to prevent this, is to explicitly set the initial width and height at rollout. @Smtih

I find on repeated rollover events that bigger knob buttons actually scale larger over time to the point that it discharges one huge dispatch? Do yours do the same? I hope not as I am not a particular fan of growing knobs on frequent user interaction! I am looking at the image of ‘a big one’ (knob button) and am curious as to how well it handles rollover events.

They are pretty good tools to make buttons and stuff. When i see these knobs i am pretty impressed, but as all good things there is allways room to improve it. Like the suggestion of Joe, well maybe i use them in my current project with some minor adjustments. Don't know which yet. I am busy with the making of controls with Flash artwork used in Flex.

Using vertical movements to adjust the value would give a much better user-experience. It's straight forward to overwrite the mouseHandlers to get this interaction and I'll keep this in mind the next time I'll revisit knobs. thanks Joe
