How to make rotating menu selections

in Working with GS (Mac)
I am looking to do something similar to the UI on the iPhone when you set the time for an appointment. You have a spinning "wheel" of choices with the center highlighted and the user swipes up or down to move the "wheel" till their choice is in the highlight. Has anyone done this? Is there a tutorial or template out there I can see/buy? I don't think it'd be all that hard, but I also don't want to reinvent the wheel. :)

thanks,
Shawn

    I think he means more like this:

    Shouldn't be too hard, a bit of 'sin' and some vertical scaling.

    Yup, that's exactly what I mean. thanks for the visual Socks. I'm good with vertical or horizontally oriented.

    Just noticed that Apple don't scale their type as if on a cylinder (see image below - all type is the same height), which makes life much more easy . . . .so with that in mind I will give this a quick go:

    If @socks is giving this ago, your can bet your bottom dollar his solution will be AAA*sin( self.Time *BBB)+CCC

    Anything else and he's stolen the code

    Here's a quick rough idea, you'd need to decide how you want the selections to lock to the centre (up/down buttons?) as well as playing around with the images to get a more convincing 'barrel' effect + a nice clicking sound wouldn't go amiss, but this should give you a basic idea to start from.

    (Also, for this kind of quick and easy set up to work you would have to have this scroll wheel as the bottom layer of a menu - as it has a couple of 'blanking panels' hiding the text list - hope that makes sense.)

    I don't know what you mean, all my demos use high quality ingredients sourced from reputable growers, my tomatoes are from Italy, my horse meat is from the UK and all my attributes are organic.

    @socks Organic smanic! I've got video evidence of you using pesticides on your attributes!

    Took a look at the demo, bit of a problem in your otherwise rule .. Its all focused to the X velocity and not the Y ;)

    I guess if you wanted to take this one step further, you could combine your masking techniques with a vertical coverflow, no growth on the individual slats but you could then combine a snap to middle function to always straighten out the scroll upon its slow down.

    Nothing more than a light dusting of Methionylthreonylthreonylglutamin (+ some lead and this dark brown stuff I get from the petrol/gas station).

    Damn ! I told you I threw it together, yeah, you'd need to sort that out, in fact I don't even know what that's for, that part of the code was stolen from someone else (I forget, probably someone clever, it's not [AAA*sin( self.Time *BBB)+CCC] after all).

    Yep, perfect ! I'll let someone else do all the actual hard work.

    During my time as a postman, that's what my 8th wife (big "babs" Barbara) used to say, lovely woman but very violent / unpredictable.
