【solved】How to Get Drawcall of UIPanel through Script?

[dreamever99]

I have tried  UIDrawCall.Count(panel) ,  panel.drawCalls.Count. They all return 0, both in run time and editor mode.
so, can anybody tell me how to get UIPrefab's drawcall through Script?

ps. I know I could use NGUI Drawcall Tool to see the drawcall. But I would like to get all the data through script automatically not just one by one through NGUI DrawcallTool.

Thanks for hints from ArenMook.
I also read source code about UIDrawcallViewer of NGUI.
Select the GameObject in  Hierarchy then the UIDrawcall.Count(Panel) can work.

Prefabs don't have draw calls. Prefabs don't exist in the scene.

Prefab instances is what you see when you drag a prefab into the scene, at which point the actual draw calls get created.

UIDrawCall.Count(panel) will indeed give you the number of active draw calls for that panel. Keyword being "active" -- if a panel is disabled or isn't actually in the scene, this will be 0.
