UILabel chat question

[elvess]

Hello. I need a chat. And I made it according to the example in NGUI 2.7. But i need to scroll it when the length of message is bigger than chat panel. I can do it by wheel on PC but cant on Android by finger. How can I scroll chat window with finger?

Add the following function to the UITextList:

1.         void OnDrag (Vector2 delta)
2.         {
3.                 if (textLabel != null)
4.                 {
5.                         float val = delta.y * ((style == Style.Chat) ? -1f / textLabel.fontSize : 1f / textLabel.fontSize);
6.                         mScroll = Mathf.Max(0f, mScroll + val);
7.                         UpdateVisibleText();
8.                 }
9.         }

An error: "Assets/NGUI/Scripts/UI/UITextList.cs(132,76): error CS1061: Type `UILabel' does not contain a definition for `fontSize' and no extension method `fontSize' of type `UILabel' could be found (are you missing a using directive or an assembly reference?)"

Ah, 2.7... yeah that  one won't have font size. You can use bitmapFont.size instead I think. Currently the latest of the 3.X cycle that's in the Professional repository has an improved text list script that adds both touch and scroll bar support.
