Title: UIInput EventDelegate.Add onSelect/onDeselect?
Post by: petrs on May 09, 2014, 02:56:42 PM
Hi,

How on earth can you set an onSelect or onDeselect EventDelegate (via EventDelegate.Add ())?

Basically I'm trying to simply detect focus on or focus off a dynamically created UIInput, hence the need for using EventDelegate.Add. Currently there are no onSelect or onDeselect defines for UIInput.

Er, you don't. EventDelegate is a class type. Your question is the equivalent of asking "how can you set onSelect using a List (via List.Add())?". It doesn't make much sense.

If you want to receive OnSelect, then do just that. Add an OnSelect function.
  1. using UnityEngine;
  2.  
  3. public class Test : MonoBehaviour
  4. {
  5.     void OnSelect (bool isSelected)
  6.     {
  7.         Debug.Log("Selection: " + isSelected);
  8.     }
  9. }
Now, if you want to trigger some remote function instead of writing a script... then attach UIEventTrigger, and you can do it via inspector or EventDelegate.Add(GetComponent<UIEventTrigger>().onSelect, YourFunction);

I guess I really meant that onSelect and onDeselect should be added to UIInput's default delegates along with onChange, onSubmit and onValidate. (Or onGainFocus and onLoseFocus)

There seem to be many threads asking a similar thing. Writing an OnSelect handler is ok for simple apps, but if you are dealing with thousands of various groupings of NGUI components things get a bit convoluted. Sure I could change the original source code to support onSelect and onDeselect, but I'd rather not so I can upgrade easily. Currently I have written handler which suffices, but I feel its not the cleanest solution.

I think UIInput should have at least a default event delegate for losing focus, since this normally would trigger either a submit or erase action.

I'd rather not clutter the inspector any more than needed. You can already do that by attaching UIEventTrigger. It has all the notification types for your usage.
