I did a search on this issue and only came up with the question I asked awhile back. I got no answers then, but was hoping for better luck this time. I would greatly appreciate!!

Does anybody know how to prevent text from truncating in the pickwheel? As each line comes into focus while scrolling, the text enlarges and "...." replaces some of the last letters. Changing textsize and size of the button doesn't help.

You'll have to forgive me if this seems a dense or obtuse question, but what is a pickwheel? Can you post a picture of what your trying to accomplish? Even if it is just a sketch or doodle, it may help you get the answers you need.

If you own any cellphone (unlike me ), you surely will have seen and used this.
See attached pic...

I actually *did* get a cell phone recently, but it has nothing like that. Of course, I should also point out that it is a phone that is very limited, not powered by one of the big two Os's, etc. Interesting to know what a pickwheel is, though, I had only seen a reference to it in a completely different language.

Looking at it, though, the only way I could see text getting trucated is if the font were too large, or if the margins were some how off? It looks like a regular field to me.

Pickwheels are only on iOS, it's an Apple interface.

The OS controls it, I don't think it's possible to change its behavior or appearance. About all you can do is use shorter strings.

That's what I thought, Jacques. The pickwheel on the old iPhones didn't do the truncating and looked more like the posted example. It's not a life or death matter, but would be nice to be able to control the handling of the text there.

See the paragraph "Variable Width Presentation Strings" in

So you may have to issue a feature request for LC's iOS part ...

Truncating, as Jacque suggests, seems the best way to go. However you could break a long line into multiple lines.
For example consider this list of three fruits:

• Cherry
  Peeled and sliced banana
  Peach

Line 2 may be too long to fit into the picker. So, you might break line 2 into two lines, inserting a couple of spaces into the extra line to give an indented appearance:

• Cherry
  Peeled and
  — sliced banana
  Peach

You'd then map the value of the selected line to the fruit list:
1 = Cherry
2 or 3 = Banana
4 = Peach

Admittedly this is a very kludgey and non-standard alternative.

I like that

The only way I've been able to get around this is to set the last choice in the pickWheel list to be a series of "-- ---- ----- --- ---" dashes and spaces. I keep playing with the size until the truncation is eliminated. Of course you have to handle the event when the user selects the last item in the pickWheel.

Thank you!! I look forward to trying this out.
