How to - Selecting from a List?

I am looking for an elegant way to select a line from a text list, eg. a name from a list of login names.

It can likely be achieved using the Scroll View example, but that would be cumbersome. It would be nice to return the line/paragraph index or content from a line selected in a scrolling text field.

Anyone got a strategy? I can't see anything obvious in the API.

 

Also interested in this.

 

I'm implementing a multiplayer game browser which is kinda this. I created a "line item" prefab which has a Selectable component on it (as well as some child Text boxes), and then instantiate it into a scrolling rect:

Code (CSharp):

1. var entry = (GameObject) Instantiate(BrowserEntryPrefab, new Vector3(0, y, 0), Quaternion.identity);
2. entry.transform.SetParent(EntriesPanel.transform, false);
3.  
4. var ent = new EventTrigger.Entry();
5. var cb = new EventTrigger.TriggerEvent();
6. cb.AddListener(RoomClicked);
7. ent.callback = cb;
8. ent.eventID = EventTriggerType.PointerClick;
9. entry.GetComponent<EventTrigger>().delegates.Add(ent);
10.  
11. entry.transform.FindChild("Name").GetComponent<Text>().text = "blah";
12.  
13. y -= 20f;
14. if (y < -158) height += 20f;
15. EntriesPanel.GetComponent<RectTransform>().sizeDelta = new Vector2(EntriesPanel.GetComponent<RectTransform>().sizeDelta.x, height);

The last bit is spacing the items out vertically, and resizing the parent panel which acts as the Content for the scroll rect. I had to resize the panel manually as otherwise the items simply overflowed out the bottom and the scroll content size never changes.

This is messy and inelegant, but until someone makes some decent controls (ListView, DropDownList, DataGrid) we're probably stuck doing stuff like this. Hope someone points out a better method!

 

Hi guys,

Our product, "ListView for Unity UI", sounds like it is exactly what you need. It's a fully featured ListView control that uses the same code interface as the .NET control.
