List with Selection that can render 100s of items

[amraffay]

Hi,

I'm creating an app like game which will have list with complex items (icon, label and accesssory).
How can i achieve something like that with NGUI?
Thanks

Just do it? I am not sure I understand the question. If you want to do it very efficiently, look at endless scroll views.

I'm actually new to NGUI so what are the steps to achieve that?
Should i use scrollView with Grid? and add items dynamically using NGUITools.AddChild?
or something else?

Thanks

Make each entry as a prefab and add them when the scrollview is created? You can have a grid place them. Look in the examples folder at the endless scrollview scene to see how it could be done.

I'm actually adding contents dynamically using

1. NGUITools.AddChild (list.gameObject, galleryItem);
2. list.Reposition ();
3.  

However problem is as galleryitem is using UIDragScrollView which require reference to scroll vew (in my case on runtime)
So i have this code attached to galleryitem

1.         void Start () {
2.        
3.                 GetComponent<UIDragScrollView> ().scrollView = GameObject.Find("Scroll View").GetComponent<UIScrollView>();
4.  
5.  
6.         }

It doesnt look efficient, as ill b adding 100s of items on runtime
What'd you suggest?

Thanks

Have a reference to the scrollview in and do this:

1. //public UIScrollView scrollView; //set in the spawner prefab
2. var go = NGUITools.AddChild (list.gameObject, galleryItem);
3. go.GetComponent<UIDragScrollView>().scrollview = scrollView;
4. list.Reposition ();
5.  

The getcomponent isn't too bad, but .Find suuucks.

Much better now, Thanks

Now the remaining issue is how can i make list item selectable and listen to change event?

Put a UIToggle on the items and give it the same group.
