Possible addition to UILocalize

[ranilian]

1. mLanguage = loc.currentLanguage;
2. if (gameObject.GetComponent<BoxCollider> () != null) {
3. // Re-adjust the collider dimensions
4. NGUITools.AddWidgetCollider (gameObject);
5. }

To re-adjust the collider size of the text if it already has one on it.

[ArenMook]

The collider should generally be added to the parent game object, not to the localized label/sprite. For example, "button" game object instead of the background sliced sprite or the text label under it.

[ranilian]

That is true only if you have a background behind your text. In our case, the text is our button.

You can also create your own additional script with

1. void OnLocalize (Localization loc)

...function inside. Inside this function you can resize the collider accordingly.
