Component request: rotational slider aka "the Knob"

Hi David, hi all,

I'd like to share an idea for a new special parameter component - the rotating knob:

It could be useful for controling angle/circle/cycle related data/geometry.


I imagine it would have the following settings:

start - value at "0:00" (default = 0)
end - value at "12:00" (default = 1 or 2Pi)
min - minimum possible value (default = start)
max - maximum possible value (default = end)
loopcount - boolean (default = false)
infinite - boolean (default = false), if true then min & max obsolete
+ the usual slider settings (rounding, digits...)

example usages:

a) potentiometer
start=0, end=1023, min=0, max=1023, loopcount=false, infinite=false
same as typical slider, but with circular motion

b) crank/winch
start=0, end=2Pi, min=0, max=N*2Pi, loopcount=true, inifinte=false
intuitive control over "winding" count

c) spinning wheel
start=0, end=2Pi, min=null, max=null, loopcount=false, infinite=true
useful for continuous (no stopping on the end-start seam) angle picking

What do you think?

"up!"

forgive my bluntness, but I've gotta fealing you've got to fight for attention since the general discussion forum is so popular nowadays ;-)

btw. maybe the errors&bugs section would be more suitable for posts like this? (errors,bugs&suggestions?)

that is awesone.

Can we change the color or name them?

I'd also like to request to implement a secret combination and a special prize for unlocking it ;-)

May I request "initialization code" (pop-up) ? Like "o10<10.2<11"

Awesome! Can't wait to see it implemented.

Can I request for "lock (freeze) location" option to avoid incidental dragging?

Nice, now I can make Batman's Decoder like he has in Arkham City!

just a thought. the ability to toggle radians and degrees. on the dial.

It's not angles. It's like a cyclical slider. You pick the amount of values for a full turn and also set a minimum and maximum.

Presumably it will have an "expression" like the slider in which you can change the behaviour.
