Hi Mel,
I'm not sure if this is what your looking for,
http://www.domainsoftworx.com/ has somthing called "SuperSlider" but it is
mac only.
http://www.914fan.net/CustomClass/ is a tutorial for building a knob
control.

Subject: Custom Canvas Controls
I've been looking around for some examples or source for custom canvas
controls, specifically knob or slider styles. And of course, found very
little.
There appears in the NUG list a lot of requests over the years for these
types of controls but very little offered in response to them.
For anyone designing anything from a controller (midi, volume, mixers) to
who knows what, these types of controls would be far more graphically
pleasing than the RB slider. And hopefully one heck of a lot more
versatile.
For example, a slider class could have hatch marks/numbers/bar graph on
left or right side (top or bottom for horizontal controls), custom
"thumbs", static fields linked to the control for the display of the
control current setting, a bypass mode so a control could be set without
generating a "change" event and so on. Add in the usual min/
max/current/step and the ability to handle "center" as off (like a
pan/balance control in audio), direction left to right or bottom to top
(or vice versa) and you'd have one nicely rounded out control.
I put an example sample of a few controls on my server:

Since controls like this don't appear to exist, I wonder if it's because
it's quite difficult to write the control, or the ROI would be quite low
so it's not worth the effort for a developer?
I don't think that I'd have the required ability to create a control like
this, but I'm sure that many do. Perhaps if others joined in, we could
entice someone to create a package of custom canvas controls to sell at a
reasonable cost.
If not, well there's always the RB "slider" ...shudder...:-)
