PopUp menu

[Ransu]

Hi, I am new to NGUI and coding so bare with me. There is a tutorial example 11 that shows a POPUP menu.
How do I get a text (label) to show texts according to the selection of the POPUP selection.
Like POPUP alternatives (1,2,3,4)
Pressing 1 - show label "1 is a number"
Pressing 2 - show label "2 is also a number"
Thankful for any help, and please explain clearly as to a noob!

Write a script that will register to receive UISlider.onValueChange notifications and do what you want with the selection.

In the tutorial 11 in NGUI, I can see the following code on the SlicedSprite "X" that changes color.

using UnityEngine;
[ExecuteInEditMode]
[RequireComponent(typeof(UIWidget))]
[AddComponentMenu("NGUI/Examples/Set Color on Selection")]
public class SetColorOnSelection : MonoBehaviour{
   UIWidget mWidget;
   void OnSelectionChange (string val){
      if (mWidget == null) mWidget = GetComponent<UIWidget>();
      switch (val)
      {
         case "White":   mWidget.color = Color.white;   break;
         case "Red":   mWidget.color = Color.red;      break;
         case "Green":   mWidget.color = Color.green;   break;
         case "Blue":   mWidget.color = Color.blue;      break;
         case "Yellow":   mWidget.color = Color.yellow;   break;
         case "Cyan":   mWidget.color = Color.cyan;      break;
         case "Magenta":     mWidget.color = Color.magenta;   break;
      }
   }
}

If I add a new SlicedSprite of the X and add the code SetColorOnSelection onto it, this mew slicedsprite won´t change color?

If the UISlider.onValueChange is the solution, could someone please write the code, howto do it.

For the script you posted to work it needs to be attached to the drop-down list, and the drop down's list event notification function must be called SetColorOnSelection. This script works with a drop-down list, not with a slider. To listen to slider changes, use UISlider.onValueChange += YourFunction.
