PopUpList

[Antiloco]

Hi all,

I'm using UIPopUpList with some item (item1,item2,item3).
I have the necessity to show popup with the value set to empty, the first time that I show this control.
I set UIPopUpList.value="" and works fine, but the when i click on popup to make a choice,  Highlight sprite is shown outside item list area.
I have looked UIPopUpList.cs code at Onclick method, and I understand that happen because empty value doesn't  matches any values in item list.

TO solve this I have modified script in  this way

// Move the selection here if this is the right label            
   if (mSelectedItem == s || i==0)
      Highlight (lbl, true);

adding OR with i variable , I highlight the first item if there isn't  correspondence with popup value and popup list.

it is the correct way or is there another solution?


Thanks

It sounds fine, but I can't check right now as I'm on vacation.

I have recently updated my NGUI version and , obviously , the update has overwritten my changes in UIPopList.cs
Is there a way to obtain the same result  without change UIPopList.cs  script?

Thanks.

The popup list isn't meant to have the selected item's value be nothing. Even with your change, it breaks controller-based input. No selected item, what do up/down arrows do? I suggest always defaulting to the first item in the list instead.

Add this right above the "// Run through all items and create labels for each one"

1.                         // Ensure we have a valid selection
2.                         if (string.IsNullOrEmpty(mSelectedItem) && items.Count > 0)
3.                                 mSelectedItem = items[0];

That said... I'll make some changes to make it possible to do what you're trying to do in the next release.
