I woul use an animation frame that matches the marks on your dial. When user clicks on that area change the frame to +\- 1

thanks for the tip, mikec!

The problem is:
you could dial it at every position around, you know?
but the marker will allways start from its position.
(because you could turn the dial around more than
one time)

ie:
turn one: day 1 - 12
turn two: day 13 - 25
turn three: day 26 - 38
(after the last day of the month, it jumps back to day 1)

so you should be able to track the move of the user.

Can't you make it so while you keep pressing the finger down in an area above it you make it look at the finger position.
You can do that by finding the angle between the center of the wheel to the finger - either with the advanced direction object or with some math in the expression editor.

You can then turn the angle value into whatever value you are interested in.

Stingray,..what exactly do you want the dial to do? What's the project you are working on?

[StingRay]

Hi! It's a 'booking table form'.

you choose the date/time (3 dials at one screen)
(month - day - time)

how many persons (1 dial)

and fill out a form. its just a different way, you know?
i have no idea if i could use the iphone-picker with mmf. but i dont think so...

[KLiK-iT]

Oh I see,.now that makes sense. So,.you would have 4 dials.

Dial 1= How many Persons

Dial 2= Month

Dial 3= Day

Dial 4= Time

Is that right?

[StingRay]

yes, youre right.

[KLiK-iT]

OK,.one more thing,.can you PM me the mfa? I can most likley do this,.but I need to see what is going on in the project.

Not sure if it helps, but the List object becomes the iPhone Picker on the iPhone. Not sure if you can have a bunch of them on screen though - but this would be the normal way of doing date & time on iPhone
