Setting the startIndex value of a pickerwheel dynamically

Solar2D Composer
#1

I’m using a single column picker wheel in my latest app to allow people to select one of a number of values , I see from the docs that I can startIndex when I create the wheel, but I can’t seen to work out how to change that selection outside of the initial call.

I need to allow users to edit existing values from a DB, but no matter what i’ve tried it doesn’t seem to do anything, for instance, here’s the original definition (measures is a simple table containing string values):

 picker = widget.newPickerWheel{  
 id = "chooseSizePicker",  
 font = "CenturyGothic",  
 top = 185,  
 columns = measures,  
 }

and here’s what I’ve tried to do in Scene:enterScene (obv using storyBoard)

 picker.columns[1].startIndex = 6

…but nothing triggers…

Anyone know why?

TIA

also, is there any way to dynamically add items to the picker’s column(s) after it’s been instantiated? [import]uid: 45444 topic_id: 32380 reply_id: 128795[/import]

Was this question answered? Because I would like to do the same thing. I want to update the picker wheel from global context when I switch to the storyboard that contains the picker. :slight_smile:

Hi @chris841, @crussell,

At this time, the pickerWheel doesn’t support post-instantiation adding/removing of column data. You would need to replace the widget with the updated data.
