Picker Wheel missing method ?

[jch_apple]

Corona"s Picker Wheel seems to lack the ability of changing one column depending on the value of others.

For instance if you need to setup a picker date with 3 columns (month, day, year) showing February should update the days columns in order to display only 1 to 29 or 28, depending on the year.Same for April and so on.

This could be achieved by a listener but the only way to do that seems to check the values with a timer:performWithDelay, a non very efficient method.

Is there any other workaround, or future update for this ?

I just posted my first attempt at a workaround for this, but like you said, it’s not very efficient.

It works nicely for choosing dates, but it could use some improving. I’m sure it could be made more generic, so you could initialize the table with a multi-dimensional array instead of the current hard-coded labels.
